PROBLEM TO BE SOLVED: To provide a multilayer stretched film for cold forming, the film without the occurrence of pin holes or cracks in cold forming and without delamination in a molded article obtained after the cold forming when exposed at a high temperature.SOLUTION: A multilayer stretched film for cold forming is obtained by biaxially stretching a multilayer laminate having at least three layers, that is, a polyester layer (layer A), an adhesive layer (layer B), and a polyamide layer (layer C), in which the layer A includes a crystalline polyester, the layer B includes a sulfone group-containing polyester, the layer C includes an aliphatic polyamide, and the tensile strength change in 30-70% tensile elongation is 40-150 MPa. |
