Lamination film and packaging material

PROBLEM TO BE SOLVED: To provide a lamination film that excels in surface heat-resistance while having suitable packaging machine suitability and that can be used in a single form not using a stretched base material or the like.SOLUTION: The present invention relates to a lamination film used in a packaging material. The lamination film has a heat-resistant coat layer on a resin base material. The surface layer of the resin base material, which is opposite the side of the heat-resistant coat layer having the heat-resistant coat layer on the resin base material, is formed from a heat-sealable thermoplastic resin layer. The heat resistant coat layer is a lamination film, which is a layer of cellulose acetate coating agent containing cellulose acetate and organic solvent. The lamination film has an appropriate packaging machine suitability and heat resistance and can be used in a single form not using a stretched base material.SELECTED DRAWING: None
