Process for making a recloseable package
View Patent ↗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.
1. A process for packaging a product, comprising:
a. providing a flat web of material having first and second edges and a zipper including first and second interlocking members, said first interlocking member being attached to said web on a line that divides said web into a first segment and a second segment;
b. folding said first segment back toward said second segment to expose a first end and a second end of said zipper;
c. cutting a series of spaced notches on said zipper while said first end and said second end are exposed, each of said notches being located at a side edge of individual packages formed by said flat web;
d. moving sliders over said zipper at said notches;
e. placing one of said sliders in a respective one of said notches;
f. placing the product on the web; and
g. forming individual packages of said product from said web.
2. The process of claim 1 , further including folding said first segment around said zipper such that said first segment encapsulates said zipper and extends over an attachment region of said second interlocking member.
3. The process of claim 2 , further including placing said product on said second segment and folding said second segment around said product.
4. The process of claim 3 , further including attaching said first segment to said attachment region of said second interlocking member.
5. The process of claim 1 , further including moving said web with said attached zipper and associated sliders to a flow-wrap processing machine.
6. The process of claim 1 , further including moving said web with said attached zipper and associated sliders to a horizontal form-fill-seal machine.
7. The process of claim 1 , further including moving said web with said attached zipper and associated sliders to a vertical form-fill-seal machine.
8. The process of claim 1 , wherein said cutting of said notches does not substantially stretch said zipper due to said attachment of said zipper to said web when said cutting occurs.
9. The process of claim 1 , wherein said product is placed on said second segment.
