ABSTRACT:
Snap and fill plastic film bags and a process of opening and placing product in the plastic film bags. A reclosable zipper is provided at the opening of the bag leading to the bag cavity. A lip extends from the front wall above the reclosable zipper and a header portion extends from the back wall above the reclosable zipper. A part of the header portion is supported on a support structure for carrying the bag and a perforation is provided on the header portion above the reclosable zipper. The bags are initially closed and, during the process of opening and placing product therein, the operator grips the bag front wall lip and by pulling the lip away from the support structure, the complementary zipper profiles are separated and, thus, opening the bag. Further pulling of the lip from the support structure causes the severing of the bag from the header portion at the perforation. Thereafter, the operator places product in the bag cavity through the bag opening and the zipper profiles are joined for closing the bag and sealing the products therein.
