ABSTRACT:
A reclosable fastener assembly (10) for use in the manufacture of a plastic bag (30). The fastener assembly (10) includes a zipper (18) with a seal feature on a web flange (24) extending from an interlocking member (26) of a profile (28) of the zipper (18). The web flange (24) is bent at a lower portion of the web flange (24) upward to the interlocking member (26). At the lower portion, an interior face (32) of the web flange (24) is sealed to an opposite interior face (33) to form a flange seal (31). The bend (35) of the lower portion includes a weakness area (34) which, in concert with the flange seal (31), acts as a barrier and a tamper-evident feature. After the flange seal (31) is initially tom open, the weakness area (34) may be torn open to access the plastic bag (30). A method for making a reclosable plastic bag (30) is also disclosed.
