The Fresh-Lock Zipper brand of Presto Products has a line of polypropylene zippers for retort and other high-temperature packaging applications. The zippers are capable of resisting the high temperatures demanded by the retort process. For the first time ever, food processors and institutional customers will reap the rewards of reclosable retort pouches that offer all-in-one serve, seal and store design. The Fresh-Lock zippers are available for both bottom-fill and top-fill pouch applications, and can be used in stand-up pouch or three-side-seal pouch designs. The zippers are designed for use in wet, moist or dry applications and can be modified to meet the specific requirement of the product and package design. New equipment is not required because the zipper is easily incorporated into existing form-fill-seal equipment currently being used for zipper applications. The reclosable retort zippers allow users to store the food in its original container. They are used for a wide variety of products, including meat, poultry, tuna, seafood, stews, soups, prepared rice, gravy, sauces, prepared meals, fruits, vegetables and pet foods. Fresh-Lock® retort zippers are available in three styles: general use retort zippers, zippers for a 3-side-seal, bottom-fill pouch, and zippers for a stand-up, top-fill pouch. They are also available in institutional sizes. Pouches with new Fresh-Lock retort zippers provide marketers with a large surface for graphics, resulting in more shelf impact and brand differentiation. Zippers can be tailored to match the product and consumer demographics. Research shows that consumer demand is strong for this type of product packaging because of the convenience and product protection that it offers. Fresh-Lock Zipper’s expert technical team helps customers select the zipper that best suits their application, then integrates the zipper with the customer’s film structure, packaging design and equipment.
