Process for attaching slider operated closure on form-fill-seal packaging machinery
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 making a recloseable package, comprising:
a. providing a web of material having first and second edges, and a zipper having a first side and a second side opposite the first side and including first and second interlocking members, said first interlocking member being attached to said web and located at an intermediate portion of said web between said first and second edges, said second interlocking member having an attachment region that is facing away from said web;
b, exposing said first and second sides of said zipper by folding said web of material;
c, creating zipper segments from said zipper while said first and second sides are exposed, each of said zipper segments being for an individual product package; and
d, adding a slider onto each of said zipper segments.
2. The method of claim 1 , wherein said creating zipper segments includes presealing said zipper at spaced locations.
3. The method of claim 2 , wherein said creating zipper segments includes adding notches to said zipper at spaced locations.
4. The method of claim 3 , wherein said notches are located at said areas of said presealing.
5. The method of claim 4 , wherein said sliders are placed over said notches.
6. The method of claim 5 , further including applying an end termination for each of said zipper segments.
7. The method of claim 1 , further including applying an end termination for each of said zipper segments.
8. The method of claim 1 , further including attaching said web to said attachment region to form a pouch around said zipper and said slider.
9. The method of claim 1 , further including moving said web with said attached zipper and associated sliders to a horizontal form-fill-seal machine.
10. The method of claim 1 , further including moving said web with said attached zipper and associated sliders to a vertical form-fill-seal machine.
