These Fresh-Lock^® zippers can be used on a wide variety of package sizes, film structures, and packaging equipment. With lower sealing temperatures possible, film distortion is reduced, which improves the package’s appearance. Improved seal integrity of the sealant ribs minimizes package leakage. Consumers appreciate the extra-wide offset flange for easy grip and opening-and-closing features that keeps foods fresh and secure. The strong holding force keeps contents secure.

Presto’s patented co-extruded sealant ribs enhance the zipper’s sealability, with compatibility to a wide variety of packaging films, allowing for faster line speeds on vertical and horizontal form/fill/seal equipment as well as pouch machines that produce pre-formed pouches.
