Re-sealable, leak-proof zipper pouch for flexible packaging


Zip-Pak, a subsidiary of Illinois Tool Works (ITW), headquartered in Manteno, Ill., is the world leader in re-sealable packaging technology, offering a wide range of re-sealable zipper closure solutions. Program.

At the Worldwide Food Expo in Chicago in 2005, Zip-Pak launched a series of leak-proof zippers. It is said that food manufacturers will apply this new series of zipper products to liquid food packaging, can be re-sealed, and will not leak.

Leak-proof, safe and convenient to use

Zip-Pak said that this series of anti-seepage zipper pouches can package frozen foods and pre-prepared foods such as sauce, and can prevent the product inside the packaging from leaking to the store shelves or the shelves of the consumer's home refrigerator. .

The design principle of this new zipper is this: After the zipper of the bag is pulled, the pressure of the product in the bag causes the special shape of the zipper to be tightly locked together, thus completing a sealing seal. This sealed seal protects the food from contamination by external bacteria, thereby preventing the product from spoiling. When the consumer reuses the package, it can maintain the freshness of the product as much as possible.

The new leak-proof zipper requires 20 pounds of internal opening force, which allows the zipper to remain closed even under heavy pressure, ensuring the integrity of the package during transportation and consumer use.

This leak-proof zipper is excellent in performance and can be manufactured using horizontal FFS equipment, thermoforming and prefabricated bag production equipment, and will surely become an ideal sealing solution for many types of laminated or polyethylene film materials.

Rusty Koenigkramer, Zip-Pak's business manager at Orangeburg, NY, said: “Zip-Pak's innovative zipper technology helps food manufacturers improve the ease of use of their products. The development of this leak-proof zipper is one aspect of it. ."
