ABSTRACT:
The present invention relates to a process used for packaging a product in a web of material that has a zipper attached thereto. The process includes providing a web of material having first and second edges and a zipper including first and second interlocking members. The first and second interlocking members of the zipper are interlocked together. The first interlocking member of the zipper is attached to the web at an intermediate portion of the web between the first and second edges of the web. The second interlocking member has an attachment region that is facing away from the web. One edge of the web is folded away from the zipper and toward the other edge of the web. Unit operations are performed on the zipper to create zipper segments from the zipper while the zipper is exposed. Each of the zipper segments is associated with an individual food package made from the web.
