Abstract:
A tape-sealed bag, comprising:an enclosing structure including an obverse side and a back, said enclosing structure being formed of a film presenting first and second faces which are both heat fusible, opposed ends of the film being brought together in overlapping engagement and sealably connected one to another along a longitudinally fused area to thereby define an encircling structure of tubular configuration, and a length portion of said encircling structure including laterally fused areas at both upper and lower ends thereof thereby sealably closing said length portion of said encircling structure to define said enclosing structure, said longitudinally fused area being positioned on the back of the enclosing structure, and there being no other longitudinally fused area on the obverse side thereof;the film including an opening of desired shape formed therein;an opening fusing tape for covering said opening, said opening fusing tape being comprised of a laminated structure including a tearable layer provided in a tape form which is backed with a heat film on at least one side thereof serving as an outermost heat fusible layer and on a remaining side with a substrate layer, the outermost heat fusible layer of said opening fusing tape being fused with a portion of the film around a perimeter of said opening, such that when said opening fusing tape is pulled by a user, the heat fusible layer, over an area in which it is fused to the film around the perimeter of the opening, is separated from a remainder of said laminated structure by tearing along with the tearable layer such that the user has access to a contents of said enclosing structure without requiring tearing of said enclosing structure.
