A “One-way” valve for maintaining content freshness

This valve will only release air once a certain level of pressure is applied.



High sealability keeps the contents of the package fresh.


Air is only released from inside out and never from outside in.

A function for safety and a design for freshness

Our company’s valves are made with materials that adhere to the world’s strict requirements for food packaging, meaning they can be used with every type of food package. The non-return valve is designed to not let air pass through unless pressure is applied, keeping the contents of the package fresh. It works for foods such as coffee, which emits gas after being packaged, and also large packages that must be deflated when loaded onto a pallet.
