LAMINATE MATERIAL AND PACKAGING BAG USING IT

PROBLEM TO BE SOLVED: To realize beauty or the like of a surface decoration without impairing functionability or the like by sequentially laminating a print pattern layer of an aqueous ink composition, an aqueous adhesive layer, an aqueous anchor coating agent layer or a solventless adhesive layer and a heat sealable resin layer on a surface of a base material film. SOLUTION: A print pattern layer 3 of an aqueous ink composition is formed on a surface of a base material film 2. Then, an aqueous adhesive layer 4 of an aqueous adhesive, an aqueous anchor coating agent layer 4a of an aqueous anchor coating agent or a solventless adhesive layer 4b of a solventless adhesive and a heat sealable resin layer 5 are sequentially laminated. Here, the layer 5 is formed by using a linear low density polyethylene or the like. Surfaces of the layers 5 are opposed and superposed. Then, their peripheral ends are heat sealed to form a sealed part, thereby manufacturing the packaging bag. Thus, beauty or the like of a surface decoration can be realized without impairing functionability or the like.
