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; and b. 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.

Um laminate inclui geralmente: a. uma película multilayer, gas-impermeable capaz de delaminating em uma parcela gas-permeable e em uma parcela gas-impermeable, a parcela gas-permeable no adherence com a parcela gas-impermeable em uma força cohesive predeterminada da intra-película; e b. que uma película gas-permeable se ligou à película gas-impermeable em uma lig-força que fosse mais grande do que a força cohesive da intra-película entre as parcelas gas-permeable e gas-impermeable da película gas-impermeable. Nesta maneira, quando o laminate for sujeitado a uma força delaminating, os delaminates laminate dentro da película gas-impermeable tais que a parcela gas-permeable do remains gas-impermeable da película ligado à película gas-permeable. Um pacote e um método de fazer um pacote que usa o laminate como uma película lidding são divulgados também.
