Abstract
A method and apparatus for forming a resealable tubular form fill package is provided. A supply of thin thermoplastic film is continuously fed over a filling spout and formed into a tubular shape by bringing the lateral edges of the film together in an abutting face-to-face relationship. The faces of the edges are brought together at a seal location to form a fin seal. A supply of zipper closure is continuously fed adjacent the film material and adhered to the film. The film and the zipper closure are sealed and cut to produce a form fill package having a zipper closure. The zipper closure and film may be cut and sealed simultaneously.
