Abstract
A package includes a product, a bottom which supports the product, a non-barrier layer sealed to the bottom which encloses the product, a peelable barrier layer peelably disposed on the non-barrier layer and an oxygen scavenger layer, disposed between the non-barrier layer and the barrier layer. The peelable barrier layer and the oxygen scavenger layer are substantially impervious to oxygen and, when the peelable barrier layer and the oxygen scavenger layer are removed, the non-barrier layer which is substantially pervious to oxygen is exposed.
