Leakproof zipper

April 01, 2020

Have you heard of leakproof zippers? It is said that food manufacturers will apply this new series of zipper products to liquid food packaging, which can be resealed without leaking.
This series of leak-proof zipper bags can pack frozen foods and sauces and other prepared foods, and can prevent the products in the package from leaking to the store shelves or the shelves of consumers' home refrigerators.
The design principle of this new type of zipper is: after pulling the zipper of the bag, the pressure of the product in the bag will tightly lock the special shape of the zipper together to complete the seal. This hermetic seal protects the food from external bacterial contamination, thereby preventing product spoilage. When consumers reuse the packaging, it can keep the product fresh.
The new leak-proof zipper requires an internal opening force of 20 pounds. The zipper can remain closed even under heavy pressure, thereby ensuring the integrity of the package during transportation and consumer use.
This leak-proof zipper has excellent properties, can be manufactured using horizontal FFS equipment, thermoforming and prefabricated bag production equipment, and will undoubtedly become an ideal sealing solution for a variety of laminated or polyethylene film materials.
