摘要： A laminate comprising two or more films, at least one of the films being a coextruded, multilayer film, wherein the laminate delaminates within the coextruded, multilayer film when the laminate is subjected to a peel force ranging from 0.001 to 2.5 pounds per inch. The laminate advantageously provides the lid for a package and delaminates into a substantially gas-impermeable portion and a gas-permeable portion, with the gas-permeable portion being bonded directly to a product support member of the package. In this manner, the gas-impermeable portion may be peelably removed from the package to allow atmospheric oxygen to enter the interior of the package. The gas-permeable portion may be provided by perforating the delaminatable, coextruded film and bonding such film to the support member so that, when the laminate is caused to be delaminated within the perforated, coextruded film, the perforations are exposed to the ambient atmosphere and thereby allow for rapid ingress of oxygen into the interior of the package.

The film includes sequential layers A--B--C--D--C--B'--A', wherein the film may optionally not include layer A or A' and the corresponding layer B or B'. A and A' are layers substantially water and water vapor resistant, wherein at least one of the layers A and A' is made of polyolefins, polyethylene terephthalates, or co-polymers of polyethylene terephthalates. B and B' are layers adhesively bonding layers A and A' with layers C. C is a layer of a moisture absorbing polymer substantially impermeable to oxygen. The polymer is selected from the group consisting of aromatic polyamides and co-polymers of aromatic polyamides. D is a layer of a polyethylene-vinyl alcohol with a molar ethylene concentration between 0% and 80%.
