A laminate generally includes:a. a multilayer, gas-impermeable film capable of delaminating into a gas-permeable portion and a gas-impermeable portion, the gas-permeable portion in adherence with the gas-impermeable portion at a predetermined intra-film cohesive strength; andb. a gas-permeable film bonded to the gas-impermeable film at a bond-strength that is greater than the intra-film cohesive strength between the gas-permeable and gas-impermeable portions of the gas-impermeable film. In this manner, when the laminate is subjected to a delaminating force, the laminate delaminates within the gas-impermeable film such that the gas-permeable portion of the gas-impermeable film remains bonded to the gas-permeable film.A package and method of making a package using the laminate as a lidding film are also disclosed. |
