摘要: The purpose of the present invention is to provide a laminate which exhibits excellent workability during production, and is excellent in easy openability, gas barrier properties and flex resistance; and a packaging material and a pillow packaging bag each formed of the laminate. The laminate is a gas barrier laminate including at least a base material layer (A), a gas barrier adhesive layer (B), a gas barrier vapor-deposited inorganic layer (C) and a sealant layer (D). The gas barrier laminate has a configuration in which the gas barrier vapor-deposited inorganic layer (C) is in contact with the adhesive layer (B). The adhesive layer (B) has a thickness of 0.5 to 6.0 μm.

摘要: There is provided a polyethylene film and a laminate which can be used to produce a package having high heat resistance, strength and recycling suitability in place of a lamination film conventionally used in a package. The polyethylene film of the present invention is irradiated with an electron beam on its only one side, and comprises polyethylene and a crosslinking agent, in which the crosslink density of the polyethylene is different between the side irradiated with an electron beam and the other side not irradiated with an electron beam.
