ABSTRACT:
A package closure for such packages as reclosable plastic bags includes male and female interlocking profiles and a tear bead on one side of a zipper tape film. On the other side of the zipper tape film are two tear containing strips, preferably of ethylene vinyl acetate. In use, the zipper tape film is in a folded condition with male and female profiles interlocked. This places the tear containing strips on opposite sides of the outside of the folded zipper tape film, where they cooperate in serving to seal and bond packaging film to the zipper tape film, and to prevent the tear formed when the package is initially opened from running to the profiles.
