  • Laminate having a coextruded, multilayer film which delaminates and package made therefrom
    Patent number: 6033758
    Abstract: 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.
