Abstract

A laminate comprising two or more films (26, 28), at least one of the films being a coextended, multilayer film (26), wherein the laminate delaminates within the coextruded, multilayer film (26) when the laminate is subjected to a peel force ranging from 0.001 to 2.5 pounds per inch. The laminate adavantageously provides the lid (24) 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 (12) 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, coextended film (26) and bonding such film to the support member (12) so that, when the laminate is caused to be delaminated within the perforated, coextruded film (26), the perforations are exposed to the ambient atmosphere, and thereby allow for rapid ingress of oxygen into the interior of the package.
