PROBLEM TO BE SOLVED: To provide a laminate having a layer formed of a carbon-neutral polyester resin film using biomass ethylene glycol.SOLUTION: A laminate 10 includes at least two layers: a first layer 11 formed of a resin composition that essentially comprises a polyester composed of a diol unit and a dicarboxylic acid unit, in which the resin composition contains a polyester having a diol unit consisting of ethylene glycol derived from biomass and a dicarboxylic acid unit consisting of a dicarboxylic acid derived from fossil fuel, by 50 to 95 mass% with respect to the whole resin composition; and a second layer 12 formed of a resin material containing a raw material derived from biomass, which is selected from cellophane, starch, polylactic acid, nylon, polyethylene, cellulose, and the like.SELECTED DRAWING: Figure 1 |
