ABSTRACT:
A plastic zipper has a pair of female (11, 13) and male (21, 23) hooks formed on the surface of plastic films, 10, 20 and an inside of the male hooks are engaged with a pressing rib 31 to form a sealing section independent of a locking section constituted by the pair of female and male hooks. The zipper permits good hermetic sealing performance, easy opening, and easy reseating.
