     SUMMARY OF THE INVENTION 
     In accordance with the present invention there is provided a food storage bag with soaker pad. The bag of the invention includes a bag having a front and rear panel of a plastic film, the front and rear panels being closed at one end to form a bottom of the bag, the bag being open at the opposite end for receipt of food to be stored in the bag, a fluid absorbing pad located inside the bag, and an enclosure connected to the inside of the bag for containing the fluid absorbing pad. 
     An important object of the present invention is to provide a method for making film with soaker pads thereon and storage bags with soaker pads therein. 
     In accordance with the present invention, a continuous supply of bag film is fed forward to a bag making machine. Prior to entering the machine, soaker pads are placed onto the surface of the film at the locations corresponding to each resulting bag to be formed from the film. A continuous web of perforated enclosure material is fed forward in unison with the bag film and is secured to the bag film creating an enclosure that covers the soaker pads resulting in a multilayered film with pre-applied soaker pads sandwiched between its layers prior to being formed into a plurality of storage bags with soaker pads. 
     Pursuant to the principles of the present invention there is provided a new and improved storage bag with soaker pad wherein the bag has an enclosure that accomplishes a variety of tasks such as limiting the soaker pad&#39;s movement and protecting the soaker pad from becoming dislodged by the product within the bag, preventing the need to attach the soaker pad to the panels of the pad making it possible to utilize soaker pads that cannot be attached to common bag materials using conventional securing techniques, and creating a reservoir for trapping most of the fluids squeezed out the soaker pad to a confined location within the bag.

     BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to the drawings, in FIGS. 1 and 2 is shown a first embodiment of the storage bag of the invention generally indicated by the numeral 10. Bag 10 has a front panel 12 and a rear panel 14 which are preferably made from a single, integral piece of plastic film. Front panel 12 is joined to rear panel 14 by side seams 16 and 18 and by bottom fold 20. Side seams 16 and 18 have lower tapered portions 16a and 18a could be deleted and seams 16 and 18 could intersect bottom 20 perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions 16a and 18a could be shaped like an arc or a portion of an ellipse. 
     Front panel 12 has a top edge 12b which is not connected to rear panel 14, and rear panel 14 has a top edge 14b which is not connected to front panel 12. Top edge 14b is located at a distance above top edge 12b to form lip 14a. Rear panel may have wicket holes 14c adjacent the top edge 14b if desired for stacking the bags as is known in the art. If desired, top edge 12b and top edge 14b could lie immediately adjacent to each other, and lip 14a and wicket holes 14c could be eliminated. 
     Thus, an opening 22 shown in FIG. 2 is formed in the top end of bag 10. Goods such as poultry, beef, vegetables, or any other fluid exuding item may be inserted into the inside 24 of bag 10 through opening 22. Preferably, bag 10 is used to contain and store poultry. The poultry may be whole such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings. 
     Located inside bag 10 is an enclosure made from plastic film generally indicated by the numeral 26 for loosely containing the fluid absorbing pad 28 and liquids emanating from goods stored in bag 10. Although it is preferred that fluid absorbing pad 28 may be loosely contained or held in enclosure 26 and therefore be free to move therein, pad 28 could be connected to enclosure 26 to prevent movement therein if desired. 
     Enclosure 26 is connected at seam 26a to front panel 12 and at seam 26b to rear panel 14. Preferably, enclosure 26 is connected along its sides 26c and 26d shown in FIG. 3 to side seams 16 and 18 of bag 10 and to tapered portions 16a and 18a. However, if desired, enclosure 26 could be narrower than the width of bag 10. 
     In FIG. 1 and 2, seams 26a and 26b are shown connected to front panel 12 and rear panel 14, respectively, at approximately the same distance from the bottom fold 20 of bag 10. If desired, seam 26b could be located a greater distance from the bottom fold 20 than seam 26a to coincide with the borders of printed matter that may appear on the front panel 12 of bag 10. Furthermore, if desired, seam 26a or 26b could be located adjacent to bottom fold 20. 
     Fluid absorbing pad 28 is also referred to in the art, and sometimes herein, as a &#34;soaker pad&#34;. soaker pads are well known in the art and may be made from a variety of fluid absorbing materials. Soaker pad 28 may be made from manufactured or synthetic fibers, or natural fibers, or a combination thereof, either woven or non-woven, which are secured or attached to each other. Preferably, the absorbent material fibers of the fluid absorbing pad or soaker pad 28 are formed from cellulose materials such as paper or the like. 
     It is not necessary that the soaker pad 28 be covered with plastic film as disclosed in U.S. Pat. No. 5,055,332 and the like, because the soaker pad utilized in the present invention is contained in plastic film enclosure 26 and will not come in direct contact with the goods contained in bag 10. Thus, inexpensive soaker pads 28 made from absorbent materials having no plastic film cover attached thereto may be used in the bag 10 of the present invention. 
     Enclosure 26 has a plurality of perforations 30 which are substantially uniform over its full area. The perforations 30 permit liquids to travel therethrough from the goods contained in bag 10 to the soaker pad 28. Soaker pad 28 absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad 28 are retained within the enclosure 26 which functions as a fluid sump or reservoir. 
     Referring now to FIGS. 4 and 5, there is shown a second embodiment of the storage bag of the invention generally indicated by the numeral 110. Bag 110 has a front panel 112 and a rear panel 114 which are preferably made from a single, integral piece of plastic film. Front panel 112 is joined to rear panel 114 by side seams 116 and 118 and by bottom fold 120. side seams 116 and 118 have lower tapered portions 116a and 118a, respectively. However, the lower tapered portions 116a and 118a could be deleted and seams 116 and 118 could intersect bottom 120 perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions 116a and 118a could be shaped like an arc or a portion of an ellipse. 
     Front panel 112 has a top edge 112b which is not connected to rear panel 114, and rear panel 114 has a top edge 114b which is not connected to front panel 112. Top edge 114b is located at a distance above top edge 112b to form lip 114a. Rear panel may have wicket holes 114c adjacent the top edge 114b if desired for stacking the bags as is known in the art. If desired, top edge 112b and top edge 114b could lie immediately adjacent to each other, and lip 114a and wicket holes 114c could be eliminated. 
     Thus an opening 122 shown in FIG. 5 is formed in the top end of bag 110. Goods such as poultry, beef, vegetables, or any other fluid exuding item may be inserted into the inside 124 of bag 110 through opening 122. Preferably, bag 110 is used to contain and store poultry. The poultry may be whole such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings. 
     Located inside bag 110 is enclosure made from plastic film generally indicated by the numeral 126 for loosely containing the fluid absorbing pad 128, non-absorbent spacer pad 129, and liquids emanating from goods stored in bag 110. Non-absorbent spacer pad 129 maintains a space or distance between front panel 112 and enclosure 126 so that liquids may collect between front panel 112 and enclosure 126 and travel to pad 128. although it is preferred that fluid absorbing pad 128 and non-absorbent spacer pad 129 may be loosely contained or held in enclosure 126 and therefore be free to move therein, pads 128 and 129 could be connected to enclosure 126 to prevent movement therein if desired. 
     Enclosure 126 is connected at seam 126a to front panel 112 and at seam 126b to rear panel 114. Preferably, enclosure 126 is connected along its sides in the same manner as enclosure 26, shown in FIGS. 1, 2, and 3, to side seams 116 and 118 of bag 110 and to tapered portions 116a and 118a. However, if desired, enclosure 126 could be narrower than the width of bag 110. 
     In FIGS. 4 and 5, seams 126a and 126b are shown connected to front panel 112 and rear panel 114, respectively, at approximately the same distance from the bottom fold 120 of bag 110. If desired, seam 126b could be located a greater distance from the bottom fold 120 than seam 126a to coincide with the borders of printed matter that may appear on the front panel 112 of bag 110. furthermore, if desired, seam 126a or 126b could be located adjacent to bottom fold 120. 
     Fluid absorbing pad 128 is also referred to in the art, and sometimes herein, as a &#34;soaker pad&#34;. Soaker pad 128 may be constructed from the same materials and in the same manner as soaker pad 28 in FIGS. 103. 
     Enclosure 126 has a plurality of perforations 130 which are substantially uniform over its full area. The perforations 130 permit liquids to travel therethrough from the goods contained in bag 110 to the soaker pad 128. Soaker pad 128 absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad 128 are retained within the enclosure 126 which functions as a fluid sump or reservoir. 
     Referring now to FIGS. 6 and 7, there is shown a third embodiment of the storage bag of the invention generally indicated by the numeral 210. Bag 210 has a front panel 212 and a rear panel 214 which are preferably made from a single, integral piece of plastic film. Front panel 212 is joined to rear panel 214 by side seams 216 and 218 and by bottom fold 220. Side seams 216 and 218 have lower tapered portions 216a and 218a, respectively. However, the lower tapered portions 216a and 218a could be deleted and seams 216 and 218 could intersect bottom 200 perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions 216a and 218a could be shaped like an arc or a portion of an ellipse. 
     Front panel 212 has a top edge 212b which is not connected to rear panel 214, and rear panel 214 has a top edge 214b which is not connected to front panel 212. top edge 214b is located at a distance above top edge 212b to form lip 214a. Rear panel may have wicket holes 214c adjacent the top edge 214b if desired for stacking the bags as is known in the art. If desired, top edge 212b and top edge 214b could lie immediately adjacent to each other, and lip 214a and wicket holes 214c could be eliminated. 
     Thus, an opening 222 shown in FIG. 7 is formed in the top end of bag 210. Goods such as poultry, beef, vegetables, or any other fluid exuding item may be inserted into the inside 224 of bag 210 through opening 222. Preferably, bag 210 is used to contain and store poultry. The poultry may be whole, such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings. 
     Located inside bag 210 is an enclosure made from plastic film generally indicated by the numeral 226 for loosely containing the fluid absorbing pad 228, and liquids emanating from goods stored in bag 210. fluid absorbing pad 228 is placed between the rear panel 214 and the enclosure 226. A space or reservoir 229 exist between front panel 212 and enclosure 226 in space 229. Although it is preferred that fluid absorbing pad 228 may be loosely contained or held in enclosure 226 and therefore be free to move therein, pads 228 and 229 could be connected to enclosure 226 to prevent movement therein if desired. 
     Enclosure 226 is connected at seam 226a to front panel 212 and at seam 226b to rear panel 214. Preferably, enclosure 226 is connected along its sides in the same manner as enclosure 26, shown in FIGS. 1, 2, and 3, to side seams 216 and 218 of bag 210 and to tapered portions 216a and 218a. However, if desired, enclosure 226 could be narrower than the width of bag 210. 
     In FIGS. 6 and 7, seams 226a and 226b are shown connected to front panel 212 and rear panel 214, respectively, at approximately the same distance from the bottom fold 220 of bag 210. If desired, seam 226b could be located a greater distance from the bottom fold 220 than seam 226a to coincide with the borders of printed matter that may appear on the front panel 212 of bag 210. Furthermore, if desired, seam 226a or 226b could be located adjacent to bottom fold 220. 
     Fluid absorbing pad 228 is also referred to in the art, and sometimes herein, as a &#34;soaker pad&#34;. Soaker pad 228 may be constructed from the same materials and in the same manner as soaker pad 28 in FIGS. 1-3. 
     Enclosure 226 has a plurality of perforations 230 which are substantially uniform over its full area. The perforations 230 permit liquids to travel therethrough from the goods contained in bag 210 to the soaker pad 228. Soaker pad 228 absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad 228 are retained within the enclosure 226 and reservoir 229 which functions as a fluid sump or reservoir. 
     In FIG. 8 is shown the preferred method of producing soaker pad web material 300 shown in FIG. 9 with soaker pads 328 sandwiched between bag film 315 and perforated enclosure material 325. The preferred method of producing soaker pad web material 300 requires a continuous supply of opaque perforated plastic enclosure material 325 be fed forwardly in a bag forming direction. Perforated enclosure material 325 could be produced by feeding a transparent or opaque plastic web material 323 through a mechanism 350 capable of creating perforated holes 330 through material 323. Mechanisms such as mechanism 350 are well known in the art whereby the perforated holes 330 are normally produced by mechanical punching or electrically burning through the web material in the desired locations. Any device known in the art for producing perforated film could be used with the present invention. 
     After plastic web material 323 has been perforated producing perforated enclosure material 325, soaker pads 328 are individually cut from preferably a continuous roll of soaker pad material 327 by mechanism 360 and placed upon the perforated enclosure material 325 as it is moved forward. Mechanism 360 includes preferably a rotary cutting device 362 for feeding and cutting off enough soaker pad material 327 to produce soaker pads 328. Soaker pads 328 after being cut off of the roll of soaker pad material 327 are preferably moved from rotary cutter 362 and positioned on perforated enclosure material 325 by vacuum wheel 364 which creates suction pressure at vacuum wheel head 365 through vacuum holes 366. As vacuum wheel 364 rotates the suction pressure decreases so that the soaker pad 328 is released from the vacuum head 365 and deposited onto the perforated enclosure material 325 in the desired location. Mechanisms such as mechanisms 360 and 364 are well know in the art. Other mechanisms well known in the art for delivering and positioning soaker pads onto a surface could also be used, such as mechanisms that deliver and position precut soaker pads from a magazine. Any device known in the art for cutting and supplying soaker pads onto a surface could be used with the present invention. Alternatively, the enclosure material 325 and the bag film 315 could exchange place with each other in FIG. 8 and the soaker pad 328 would be positioned onto the bag film 315 by the soaker pad positioning and cutting mechanism 327 prior to the two web materials being sealed together as previously described above. 
     After the soaker pads 328 have been cut and positioned onto the perforated enclosure material 325, a continuous layer of preferably printed transparent bag film 315 is laid over the perforated enclosure material 325 thereby sandwiching the soaker pads 328 between the bag film 315 and the enclosure material 325. The width of the bag film 315 is preferably substantially wider than the width of the enclosure material 325 resulting in the enclosure material edges 325a and 325b being connected to the surface of the bag film 315 a substantial distance away from the bag film edges 315a and 315b. 
     As the enclosure material 325, containing the soaker pads 328 and the bag film 315, are fed forwardly, the enclosure material edges 325a and 325b are connected by heat sealing mechanism 370 to the surface of the bag film 315 forming seams 326a and 326b shown in FIG. 9. The seams 326a and 326b are formed adjacent to the edges 325a and 325b of enclosure material 325. Heat sealing mechanism 370 includes heat sealing devices 371 and 372 that seal the enclosure material edges 325a and 325b to the surface of the bag film 315 at seams 326a and 326b as they pass across back-up drum 375. Mechanisms such as mechanism 370 are well known in the art whereby some such mechanisms utilize devices to heat seal materials together by making direct contact to the materials to be connected while others do not make direct contact with the materials to be sealed but instead generate hot air to cause the materials to melt thereby heat sealing them together. Any device known in the art of heat sealing polymeric materials together could be utilized as the device to connect the materials together in the method of the present invention. 
     In addition to connecting the enclosure material 325 and the bag material 315 together at seams 326a and 326b , enclosure material 325 and bag material 315 could also be connected by several spot connections such as spot connections 377a and 377b formed conventional sealing mechanism 376. The spot connections 377a and 377b would prevent the soaker pads 328 from sliding between the surfaces of the enclosure material 325 and the bag film 315 along an axis parallel to the forming direction of the soaker pad web material 300. The spot connections 377a and 377b could be elongated spot connections or discontinuous seam connections or any connection type capable of limiting the movement of the pad during the bag forming process. Seams 326a and 326b also prevent the soaker pads 328 from slipping between the surfaces of the enclosure material 325 and the bag film 315 along an axis perpendicular to the forming direction of the soaker pad web material 300. Adhesives could be utilized to create the connections at seams 326a , 326b and at spots 377a and 377b as opposed to heat sealing. Adhesives used to connect polymeric materials together are well known in the art and any known adhesive could be utilized with the present invention. 
     Shown in FIG. 8A is an alternate method of positioning the soaker pad 328 between the enclosure material 325 and the bag film 315. This alternate method would feed the cut soaker pads 328 between two nip rollers such as 395 and 396. Roller 395 would feed enclosure material 325, and roller 396 feeds bag film 315, in the same direction indicated by the arrows in FIG. 8A, and the soaker pads 328 would be placed between enclosure material 325 and bag film 315 at bag length intervals. 
     Once the soaker pad web material 300 is fully formed as described above the method of the present invention would preferably include a conventional bag making machine 390 such as the bag making machine for making bags from the soaker pad web material. The bag making machine disclosed in U.S. Pat. No. 3,678,812, which is hereby incorporated by reference, may be used as the bag making machine 390. Bag making machine 390 for making bags would preferably include a conventional folding device generally indicated by the numeral 380. A conventional folding device 380 such as the folding device disclosed in U.S. Pat. No. 3,678,812. Folding device 380 folds the soaker pad web material 300 into preferably &#34;J-sheeting&#34; as is known in the art, with a first side 312b longer than a second side 314b to form a lip 314 on each resulting bag 310 as shown in FIGS. 10A and 10B. It would not be necessary to fold the soaker pad web material 300 so that one side is longer than the other, but instead, both sides could be of equal length. Machine 390 would include a conventional mechanism shown in U.S. Pat. No. 3,678,812 for cross sealing and cutting off soaker pad web material 300 to form a storage bag with soaker pad 310 as shown in FIG. 10A and 10B. Bag making machines such as bag machine 390 are well known in the art and any such machine could be utilized as the bag machine of the present invention. 
     Shown in FIG. 9 is soaker pad web material 300 comprising preferably a single continuous rectangular sheet of perforated enclosure material 325 including perforations 330 therein. However, perforated enclosure material could be formed from several pieces of material connected to each other along continuous longitudinal seams. Perforated enclosure material 325 is connected continuously adjacent to its edges 325a and 325b to bag film 315 to form seams 326a and 326b. Preferably, bag film 315 is transparent, rectangularly shaped, impervious plastic film 315. Sandwiched between the perforated enclosure material 325 and the bag film 315 are soaker pads 328. To prevent movement of the soaker pad 328 along a direction parallel to the enclosure material&#39;s edges 326a and 326b the enclosure material 325 is connected to the bag film at spot connections 377a and 377b on each side of soaker pad 328. Any number of connections of the type that limit the movement of the pad 328 between the enclosure material 325 and the bag film 315 could be included if desired. A single connection such as spot connection 377a positioned on only one side of each soaker pad 328 may be enough to prevent movement of the pad 328 depending on the web path utilized by the actual mechanisms chosen to perform the various functions required. 
     Referring now to FIGS. 10A and 10B, there is shown a fourth embodiment of the storage bag of the invention generally indicated by the numeral 310 made from bag material 300. Bag 310 has a front panel 312 and a rear panel 314 which are preferably made from a single, integral piece of transparent plastic film. Front panel 312 is joined to rear panel 314 by side seams 316 and 318 and by bottom fold 320. Side seams 316 and 318 have lower tapered portions 316a and 318a, respectively. However, the lower tapered portions 316a and 318a could be deleted and seams 316 and 318 could intersect bottom 320 perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions 316a and 318a could be shaped like an arc or a portion of an ellipse. 
     Front panel 312 has a top edge 312b which is not connected to rear panel 314, and rear panel 314 has a top edge 314b which is not connected to front panel 312. Top edge 314b is located at a distance above top edge 312b to form lip 314a. Rear panel 314 may have wicket holes 314c adjacent the top edge 314b if desired for stacking the bags as is known in the art. If desired, top edge 312b and top edge 314b could lie immediately adjacent to each other, and lip 314a and wicket holes 314c could be eliminated. 
     Thus, an opening 322 shown in FIG. 10B is formed in the top end of bag 310. Goods such as poultry, beef, vegetables, or any other fluid exuding item may be inserted into the inside 324 of bag 310 through opening 322. Preferably, bag 310 is used to contain and store poultry. The poultry may be whole such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings. 
     Located inside bag 310 is an enclosure made from preferably opaque plastic film generally indicated by the numeral 326 for loosely containing and hiding the fluid absorbing pad 328 and liquids emanating from goods stored in bag 310. Although it is preferred that fluid absorbing pad 328 may be loosely contained or held in enclosure 326 and therefore be free to move therein, pad 328 could be connected to enclosure 326 to prevent movement therein if desired. 
     Enclosure 326 is connected at seam 326ato front panel 312 and at seam 326bto rear panel 314. Preferably, enclosure 326 is connected along its sides 326c and 326d as shown in FIG. 10A to side seams 316 and 318 of bag 310 and to tapered portions 316a and 318a, and at spots 377a and 377b to front panel 312. The size of the enclosure 326 is preferably less than half the size of the combination of the front panel 312 and back panel 314 of the bag 310. 
     In FIG. 10A and 10B, seams 326a and 326b are shown connected to front panel 312 and rear panel 314, respectively. As shown, seam 326b could be located a greater distance from the bottom fold 320 than seam 326a to coincide with the borders of printed matter that may appear on the front panel 312 and back panel 314 of bag 310. Furthermore, if desired, seam 326a or 326b could be located adjacent to bottom fold 320 or both seams 326a and 326b could be located on the same front panel 312 or the same back panel 314. The perforations 330 permit liquids to travel therethrough from the goods contained in bag 310 to the soaker pad 328. Soaker pad 328 absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad 328 are retained within the enclosure 326 which functions as a fluid sump or reservoir. Perforations 330 could be spaced far enough away from seams 326a and 326b to create a dam at seams 326a and 326b to further facilitate enclosure 326 to function as a reservoir. 
     Referring now to FIGS. 11A and 11B, there is shown a fourth embodiment of the storage bag of the invention generally indicated by the numeral 410 made from bag material 300. Bag 410 has a front panel 412 and a rear panel 414 which are preferably made from a single, integral piece of transparent plastic film. Front panel 412 is joined to rear panel 414 by side seams 416 and 418 and by bottom fold 420. Side seams 416 and 418 have lower tapered portions 416a and 418a, respectively. However, the lower tapered portions 416a and 418a could be deleted and seams 416 and 418 could intersect bottom 420 perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions 416a and 418a could be shaped like an arc or a portion of an ellipse. 
     Front panel 412 has a top edge 412b which is not connected to rear panel 414, and rear panel 414 has a top edge 414b which is not connected to front panel 412. Top edge 414b is located at a distance above top edge 412b to form lip 414a. Rear panel 414 may have wicket holes 414c adjacent the top edge 414b if desired for stacking the bags as is known in the art. If desired, top edge 412b and top edge 414b could lie immediately adjacent to each other, and lip 414a and wicket holes 414c could be eliminated. 
     Thus, an opening 422 shown in FIG. 11B is formed in the top end of bag 410. Goods such as poultry, beef, vegetables, or any other fluid exuding item may be inserted into the inside 424 of bag 410 through opening 422. Preferably, bag 410 is used to contain and store poultry. The poultry may be whole such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings. 
     Located inside bag 410 is an enclosure made from preferably opaque plastic film generally indicated by the numeral 426 for loosely containing and hiding the fluid absorbing pad 328 and liquids emanating from goods stored in bag 410. Although it is preferred that fluid absorbing pad 328 may be loosely contained or held in enclosure 426 and therefore be free to move therein, pad 328 could be connected to enclosure 426 to prevent movement therein if desired. Preferably, enclosure 426 is sealed in any conventional manner such as spot welding or the like at 427 to front panel 412 near bottom 420 as shown in FIG. 11b, or to rear panel 414 near or at bottom fold 420, to prevent the bottom of enclosure 426 from being displaced upwardly toward opening 422 during the bag forming process or when goods are removed from enclosure 426. 
     Enclosure 426 is connected at seam 426a to front panel 412 and at seam 426b to rear panel 414. Preferably, enclosure 426 is connected along its sides 426c and 426d as shown in FIG. 11A to side seams 416 and 418 of bag 410 and to tapered portions 416a and 418a, and at spot weld or seal 427 to front panel 412. The size of the enclosure 426 is preferably less than half the size of the combination of the front panel 412 and back panel 414 of the bag 410. 
     In FIG. 11A and 11B, seams 426a and 426b are shown connected to front panel 412 and rear panel 414, respectively. As shown, seam 426b could be located a greater distance from the bottom fold 420 than seam 426a to coincide with the borders of printed matter that may appear on the front panel 412 and back panel 414 of bag 410. Furthermore, if desired, seam 426a or 426b could be located adjacent to bottom fold 420 or both seams 426a and 426b could be located on the same front panel 412 or the same back panel 414. 
     The perforations 430 permit liquids to travel therethrough from the goods contained in bag 410 to the soaker pad 328. Soaker pad 328 absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad 328 are retained within the enclosure 426 which functions as a fluid sump or reservoir. Perforations 430 could be spaced a substantial distance away from seams 426a and 426b thereby creating a larger dam at seams 426a and 426b to further facilitate enclosure 426 to function as a reservoir. 
     Referring now to FIGS. 12A and 12B, there is shown a fifth embodiment of the storage bag of the invention generally indicated by the numeral 510 made from bag material 300. Bag 510 has a front panel 512 and a rear panel 514 which are preferably made from a single, integral piece of transparent plastic film. Front panel 512 is joined to rear panel 514 by side seams 516 and 518 and by bottom fold 520. Side seams 516 and 518 have lower tapered portions 516a and 518a, respectively. However, the lower tapered portions 516a and 518a could be deleted and seams 516 and 518 could intersect bottom 520 perpendicularly if desired. Furthermore, rather than being formed in a straight line, the lower tapered portions 516a and 518a could be shaped like an arc or a portion of an ellipse. 
     Front panel 512 has a top edge 512b which is not connected to rear panel 514, and rear panel 514 has a top edge 514b which is not 25 connected to front panel 512. Top edge 514b is located at a distance above top edge 512b to form lip 514a. Rear panel 514 may have wicket holes 514c adjacent the top edge 514b if desired for stacking the bags as is known in the art. If desired, top edge 512b and top edge 514b could lie immediately adjacent to each other, and lip 514a and wicket holes 514c could be eliminated. 
     Thus, an opening 522 shown in FIG. 12B is formed in the top end of bag 510. Goods such as poultry, beef, vegetables, or any other fluid exuding item may be inserted into the inside 524 of bag 510 through opening 522. Preferably, bag 510 is used to contain and store poultry. The poultry may be whole such as a cleaned and dressed chicken, or the poultry may be cut into pieces such as chicken quarters, or thighs, drumsticks, or wings. 
     Located inside bag 510 connected to the inside of rear panel 514 is an enclosure made from preferably opaque plastic film generally indicated by the numeral 526 for loosely containing and hiding the fluid absorbing pad 328 and liquids emanating from goods stored in bag 510. Although it is preferred that fluid absorbing pad 328 may be loosely contained or held in enclosure 526 and therefore be free to move therein, pad 328 could be connected to enclosure 526 to prevent movement therein if desired. 
     Enclosure 526 is connected at seam 526a near the bottom 520 of rear panel 514 and at seam 526b to the upper portion of rear panel 514. If desired, enclosure 526 could be connected at seam 526a near the bottom 520 of front panel 512 and at seam 526b to the upper portion of front panel 512. Bottom seam 526a prevents the bottom of enclosure 526 from being displaced upwardly toward opening 522 during the bag forming process or when goods are removed from enclosure 526. Preferably, enclosure 526 is connected along its sides 526c and 526d as shown in FIG. 11A to side seams 516 and 518 of bag 510 and to tapered portions 516a and 518a. The size of the enclosure 526 is preferably less than half the size of the combination of the front panel 512 and back panel 514 of the bag 510. 
     In FIG. 12A and 12B, seams 526a and 526b are shown connected to rear panel 514. The perforations 530 permit liquids to travel therethrough from the goods contained in bag 510 to the soaker pad 328. Soaker pad 328 absorbs and retains the liquids from the goods. Furthermore, some of the liquids which may not be absorbed or retained by soaker pad 328 are retained within the enclosure 526 which functions as a fluid sump or reservoir. Perforations 530 could be spaced a substantial distance away from seam 526a thereby creating a larger dam at seams 526a to further facilitate enclosure 526 to function as a reservoir. 
     The enclosures, film, and bags of the invention are preferable constructed from a single piece of plastic film well known in the art. However, perforated enclosure material, film, and bags could be formed from several pieces of material connected to each other along continuous longitudinal seams. Preferably, the bags of the invention are constructed from pieces of flexible thermoplastic film such as polyvinylidene chloride, polyethylene, polypropylene, and the like. A particularly preferred thermoplastic film is polyethylene. The bags and film of the invention may be constructed by any method or methods known in the art. A preferred method of attaching the enclosures is by heat sealing. Furthermore, the bags of the invention may be made in any desired shape. Preferably, the bags 10, 110 and 210 and 310 are generally rectangular in shape, as are the enclosures 26, 126, 226, and 310 and the soaker pads 28, 128 and 228. 
     Although the preferred embodiments of the invention have been described in detail above, it should be understood that the invention is in no sense limited thereby, and its scope is to be determined by that of the following claims.
