Zipper Lock Bags

Plastic bags can be made with narrow interlocking tracks, made from the same plastic material, that are sealed into the poly bag near the open end across the width. These are called zipper bags, zip lock bags or reclosables. Typically, the user places an item in the bag and then pinches one end of the track near the seal at the side and slides their fingers across the width of the bag, forcing the poly zipper tracks to merge and lock together. Most zipper lock bags can be opened and resealed a number of times.
