Technical Examples
  1. A zipper strip for a reclosable bag or package includes a male interlocking profile and a female interlocking profile. The male interlocking profile includes a male interlocking member and a male web coextruded therewith. In like manner, the female interlocking profile includes a female interlocking member and a female web. The male interlocking member snappingly engages into the female interlocking member to join the profiles to one another. One of the male and female webs is wider than the other in at least one of two directions from the male and female interlocking members, the greater width being represented by at least one flange extending widthwise beyond the other web. The zipper strip is designed to be attached to thermoplastic sheet material by sealing the at least one flange thereto without sealing the male and female webs to each other. Methods for securing the zipper strip to thermoplastic sheet material, and for making packages on a horizontal form-fill-and-seal machine, are also disclosed.
