<P>PROBLEM TO BE SOLVED: To provide a laminate having a layer made of a carbon-neutral polyester resin film using biomass ethylene glycol. <P>SOLUTION: In the laminate 10 having at least two layers, the first layer 11 is made of a resin composition predominantly composed of polyester consisting of diol units and dicarboxylic acid units, and the second layer 12 is made of a resin material containing a material derived from fossil fuel. In the resin composition, the diol unit is ethylene glycol derived from biomass, and the dicarboxylic acid unit contains 50-95 mass% of polyester which is a dicarboxylic acid derived from fossil fuel, with respect to the whole resin composition. <P>COPYRIGHT: (C)2012,JPO&INPIT |
