According to the present invention, a multilayer film having excellent adhesive property can be manufactured even without a separate adhesive layer.
Claims16
A multilayer film, in which at least one aliphatic polycarbonate layer containing aliphatic polycarbonate and at least one polylactic acid-based polymer layer containing polylactic acid-based polymer are laminated in at least two layers.
A method for producing a multilayer film, comprising:
- a) preparing a first resin composition containing aliphatic polycarbonate;
- b) preparing a second resin composition containing polylactic acid-based polymer;
- and
- c) melting the first resin composition and the second resin composition and then coextruding the first resin composition and the second resin composition using a T-die, blown, or tubular type of extruder.
