PROBLEM TO BE SOLVED: To provide a package excellent in food hygiene, and promoting color development of meat by excellent easy opening, and a thin layer with high air permeability remaining in a bottom material.SOLUTION: A package has as a lid material, a multilayer film comprising a layer where a surface resin layer (A), an oxygen barrier resin layer (B), a pinhole resistant resin layer (C), and a heat seal resin layer (D) are laminated in the order of (A)/(B)/(C)/(D), and a peel strength of the layer (B) and the layer (C) is 0.05-5.0 N/15 mm width. In the package, the layer (D) of the multilayer film is heat sealed to a seal part of a sealed body so as to heat seal a bottom material and the lid material, and when peeling the multilayer film, the layer (C) and the layer (D) are delaminated, the layer (A), the layer (B), and the layer (C) are removed, and the thin layer of the layer (D) is exposed and remains in the sealed body. |
