POLYESTER RESIN COMPOSITION LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a laminate having a layer made of a carbon-neutral polyester resin film using biomass ethylene glycol.SOLUTION: The laminate has at least two layers. The first layer is made of a resin composition predominantly composed of polyester consisting of diol units and dicarboxylic acid units. In the resin composition, the diol unit is ethylene glycol derived from biomass, and the dicarboxylic acid unit contains 50-95 mass%, based on the whole resin composition, of polyester which is a dicarboxylic acid derived from fossil fuel. The second layer is made of a resin material containing a material derived from biomass.
