Packages and methods for differential oxygen scavenging

摘要

Packages and methods for protecting oxygen-sensitive products from damage or degradation due to oxygen contamination are provided. The packages contain at least two oxygen scavenging materials (3,4) having different oxygen scavenging properties, arranged so that oxygen contamination from different sources is effectively eliminated. Preferred packages contain at least one oxygen scavenging material (3) to effectively absorb head space oxygen, and at least one oxygen scavenging material (4) to effectively absorb ingress oxygen.
