Abstract:
A process of packaging utilizing an elongate web having front and back layers sealed together at spaced locations to define a chain of side connected, open top bags comprising:a) feeding the web along an elongated path of travel while supporting the web by grasping front and back web lips; b) the feeding step including transporting the web into and through a load station; c) as each bag is fed into the load station opening a lead portion of the bags by spreading the lips to a loading width and thereby separating the lips from each such bag by tearing separable lead lines of weakness in the front and back layers, the lead lines extending parallel to the path of travel with the length of each separable line being substantially one half the loading width in length; d) limiting the extent of lead portion opening with solid front and back web portions extending from the supporting lips toward a bottom of the bag being opened; and, e) thereafter separating the lips from a trailing portion of the bag being opened by tearing the face and back along further and spaced lines of weakness.
