Easy to remove excess gas label

Avery Dennison has developed a deflated label that allows consumers to let go of excess air or water vapor in a flexible package. If consumers want to let go of the air in stand-up pouches or other flexible packaging, simply squeeze the packaging to quickly clean the air in the package. This one-way bleed air valve reduces the volatilization of the liquid and enhances the retention of the liquid. This label is suitable for almost all packaging designs and is compatible with most automatic label production systems. A high-temperature version of this label is currently under development and will mainly be used on frozen and fresh cooked foods.
