Barrier materials absorb unwanted oxygen
Shelfplus O2 oxygen absorbers are incorporated in multilayer packaging without major changes in the package design or fabrication equipment. These “active” barrier materials are able to absorb unwanted oxygen in polyolefin packaging, and they enable packaging of oxygen-sensitive products when plastic packaging is used. It’s a moisture-activated system that works most effectively with products that have a relative humidity of 70 percent or higher.
