Laminate is said to be given a peel force of two or more films (26, 28) include, at least one of the membranes simultaneous injection molding multiple layer film 26, and the laminated body inch 0.001 to 2.5 paundeu range laminate is delaminated in the simultaneous injection molding of multiple layers film 26. Laminate advantage enemy and to provide a package lid (24), provides a substantially gas-impermeable portion and a gas-permeable portion, the gas-permeable portion is directly attached to the article support member 12 of the package. In this manner, since the gas-impermeable portions are peeled from the package is allowed to be possible to remove atmospheric oxygen from entering the inside of the package. Gas-permeable portion of the interlayer in the simultaneous injection may be provided by the shaped multiple layers aperture the film 26, by attaching a member (12) supporting these films, the multiple layer film 26 is a laminate with simultaneous injection molding when caused to be separated, since the through hole is exposed to the atmosphere of the cycle, will allow the rapid ingress of oxygen into the interior of the package.
