    • 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.
    • 用于可再封闭袋或包装的拉链带包括阳互锁轮廓和母联锁轮廓。 雄性互锁轮廓包括一个凸形互锁构件和与其共挤出的阳性腹板。 以相同的方式,母锁定轮廓包括母锁定构件和母腹板。 凸形互锁构件卡扣地接合到凹形互锁构件中以将轮廓彼此连接。 在阳型和阴型互锁构件的两个方向中的至少一个方向上,阳性和阴性腹板中的一个在另一个中宽,宽度由至少一个沿宽度方向延伸超过另一个腹板的凸缘表示。 拉链条被设计成通过将至少一个凸缘密封在其上而将阳公网和母腹板彼此密封而附接到热塑性片材。 还公开了将拉链条固定到热塑性片材材料上的方法,以及用于在水平成型 - 填充和密封机器上制造包装的方法。
