Abstract:
A gas barrier laminate of the present invention includes a biaxially-oriented polypropylene base and an aluminum oxide thin film formed on one surface of the biaxially-oriented polypropylene base. The biaxially-oriented polypropylene base has a plane orientation factor ΔP ranging from 0.005 to 0.020 according to phase-contrast measurement. Further, the gas barrier laminate of the present invention includes a biaxially-oriented polypropylene base and an aluminum oxide thin film formed on one surface of the biaxially-oriented polypropylene base. The biaxially-oriented polypropylene base has a molecular chain whose orientation angle measured by phase-contrast measurement ranges from 50° to 90° or from −50° to −90° relative to an MD direction.
Abstract:
A method for producing a laminate, the method comprising at least a pretreatment step of pretreating a surface of a substrate made of a plastic film by reactive ion etching so that the maximum displacement of the substrate surface measured by local thermal analysis is 300 nm or more, and a lamination step of laminating a thermoplastic resin layer made of a material different from that of the substrate on the pretreated surface of the substrate; wherein the plastic film is a polyethylene terephthalate film.
Abstract:
A gas barrier film including a polymer film, an anchor coat layer, and a metal oxide layer. In a gas barrier film, a polymer film and a metal oxide layer are laminated with an anchor coat layer interposed therebetween, the anchor coat layer has a thickness of 25 nm or more, and the anchor coat layer is a layer containing an acrylic resin having an organic acid group, or a layer including a cured product of a composition containing an acrylic resin having an organic acid group.
