The Fresh-Lock® string zipper is a low-cost way to add the convenience of a reclosable zipper to poly packaging and is compatible with most equipment. The Fresh-Lock® design recloses easier than competitive post-and-cavity styles.

The Fresh-Lock® string zipper is also available in easy to crush Soft Seal® Material from Fresh-Lock®, for faster cycle rates, lower sealing temperatures, improved side seal appearance and the seal won't gap or distort. The Soft Seal® Material remains flexible at colder temperatures, making it ideal for refrigerated products like cheese or tortillas.

The Fresh-Lock® string zipper is designed with a package-side indicator post for error-free feeding.
