<p>A plastic film container having a tamper-evident feature wherein a bag is provided having first and second opposing film walls (10,11) with a doubled zipper strip (13) between the film walls (10,11) at the bag top, the outer film layers (10,11) of the bag being sealed in a fin seal (12) above the zipper strip (13). Perforation lines (15,16,17,18) extend in alignment through the zipper strip (13) and the outer film layers (10,11) of the bag; sealing strips (19,20) are provided between the doubled zipper strip (13) and the layers of the bag (10,11) to block the perforations in the bag (15,16) and zipper strip (17,18). The zipper strip (13) is sealed to the film layer (10,11) so that as the top is torn off the bag, a portion of the doubled zipper strip (13) will be removed but the remaining sides of the zipper strip (13) will be attached to the bag film walls (10,11) to provide a reclosable bag. <IMAGE></p> |
