York Oxygen Absorber ActivOS is a technology where highly concentrated oxygen-absorbing active ingredients are embedded into a polymer carrier and integrated into the bottle wall through co-blown molding. The oxygen absorber primarily operates through chemical reactions and particle stretching, achieving both active and passive oxygen absorption and blocking. This effectively reduces the oxygen concentration inside the packaging, protects the contents, helps maintain high product quality over an extended period, and prolongs shelf life.

Scavenges O2 Inside
Actively absorbs residual oxygen inside the package, reducing internal oxygen concentration.
Blocks O2 Outside
The packaging material forms a barrier layer that delays the penetration of external oxygen.
