Air Valve System

Air Valve System

Avery Dennison says its low-profile air valve system protects packaged contents from moisture and contaminants, equalizes air pressure during transit and improves pallet stacking and stability.

The system, which consists of a membrane, a baffle film and a permanent adhesive, allows air expanding due to changes in temperature or altitude to escape a package through the valve membrane, equalizing pressure inside the package.

In addition to guarding packaged products, the air valve delivers shipping benefits during the transport of palletized, packaged goods, according to Avery Dennison. The system evacuates trapped air from flexible bags, allowing them to settle in a more compact and level manner. As a result, more layers of packaging can be stored on a pallet, and the pallet will bear a more stabilized load, the company says. or
