RECLOSABLE BAG AND ZIPPER THEREFOR

摘要

A reclosable zipper fastener has a slider (40) and first and second profiles (24, 26). Each profile has a body (32, 34) and a flange (28, 30) which has three zones which are, successively and in the direction away from the body, an anti­seal zone (42, 43), a line-of-weakness formation zone (44, 45) and a sealing zone (46, 47). The zipper can be used in a bag in which it is secured internally of a top seal (20), the line-of-weakness zones (44, 45) forming lines along which a top portion of the bag can be removed to open the bag. The bag can then be sealed using the zipper. A tamper-evident feature is thus provided.
