METHOD FOR PRODUCING LAMINATED BODY, AND LAMINATED BODY AND MEDICAL PACKAGING CONTAINER COMPOSED OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a laminated body which has high interlayer adhesive strength and keeps it even after heat sterilization treatment, and has low elution and excellent hygienic properties; a laminated body; and a medical packaging container.SOLUTION: A method for producing a laminated body includes: a step of laminating a melted adhesive resin composition, which contains at least one kind of a ternary copolymer of alkene-(meth)acrylic acid ester-unsaturated carboxylic acid and a binary copolymer of alkene-unsaturated carboxylic acid as an adhesive layer 2, on a transparent gas barrier film as a substrate layer 1 through an extrusion coating method, and producing an adhesive resin film 3; a step of producing a heat sealable tube 4 having heat sealability therein through an inflation method; a step of crushing the heat sealable tube 4 in a planar shape; and a step of bonding the adhesive resin film 3 on both of outer surfaces of the crushed heat sealable tube 4 through an adhesive layer 3 at such a temperature that the inner surface of the heat sealable tube 4 is not heat-fused to form a laminated body.SELECTED DRAWING: Figure 1
