ABSTRACT:
A method for attaching reclosable zipper strips transversely to thermoplastic film material which may be used to make reclosable bags or packages in a form-fill-seal machine is claimed. The zipper strip includes a male profile and a female profile. The male profile includes a male interlocking member and an integral web comprising a trailing flange and, optionally, a leading flange. Likewise, the female profile includes a female interlocking member and an integral web comprising a trailing flange and, optionally, a leading flange. As the film material is advanced into the form-fill-seal machine in bag length increments, the interlocked zipper strip is disposed on the film material transversely thereto with the trailing flange oriented in a direction opposite to the motion of the film material. The zipper strip is then sealed to the film material at its extremities. In this manner the male and female profiles are sealed to each other and to the film material. The sealing may be continuous or may take the form of spot seals.
