Abstract
The disclosure relates to a method and apparatus for manufacturing a package with a rigid or semi-rigid container and a polymeric or plastic header with a reclosure, such as a zipper.

The container, typically inverted, is filled, and the bottom is formed by folding and sealing the bottom portion of the container.

- attaching the length of zipper material to the single sheet of web material;
- attaching the continuous web material, including the continuous reclosure material attached thereto within the web material fold, to the top of the series of rigid or semi-rigid container portions thereby forming a header, the sequential rigid or semi-rigid container portions being separated by an interval;
