Abstract: PURPOSE: To ensure excellent molding processability while obtaining impact resistance by using copolyester wherein a polymer melting peak and sub-peak temp. are specific values as a main component and specifying surface orientation properties, intrinsic viscosity, the center line average roughness of a single surface and the difference between the max. and min. values of an in-plane direction refractive index. CONSTITUTION: A film for metal laminate molding processing is based on copolyester wherein polymer melting temp. is 210-257 deg.C and sub-peak temp. is 100-240 deg.C. When the polymer melting temp. is below 210 deg.C, heat resistance is insufficient and, when the polymer temp. is above 257 deg.C, moldability is insufficient. Intrinsic viscosity is set to 0.60-1.5. Further, the center line average roughness of at least a single surface, that is, a squeeze processing and/or a draw processing surface is set to 0.01-0.15μm and face orientation properties are set to 0.118-0.165. In the case of below 0.118 in surface orientation properties, impact resistance after molding is insufficient and, in a case exceeding 0.165, moldability is deteriorated. The difference between the max. and min. values of an in-plane refractive index is set to 0.06 or less.

Abstract: PURPOSE: To provide a film, which is excellent in white-light screening property and in process stability and especially suitable for molding after thermal adhesion to a metal plate by specifying the adding amount and rate of white pigment contained in both layers of a double-layer laminated film, and specifying the amount and orientation degree of oligomer contained in both layers. CONSTITUTION: This is a double-layer laminated film of a film layer (layer A), which comprises polyester-based resin A containing VAwt.% of white pigment and OAwt.% of the amount of oligomer, and a film layer (layer B), which comprises polyester-based resin B containing VBwt.% of the white pigment and OBwt.% of the amount of the oligomer. The VA and VN are set at 10-30, OA is set less than (OB-0.2), OB is set at 3wt.% or less and the orientation degree is set at 0.7-4.0, respectively. Thus, the film, which is excellent in white-light screening property and in process stability at the same time and is optimal in application for molding after thermal adhesion to a metal plate, can be obtained.

Abstract: PURPOSE: To obtain a laminate excellent in molding processability and impact resistance by controlling the max. orientation degrees on the thermal bonding side and non-thermal bonding side of a polyester biaxially stretched film to specific values after thermal bonding, molding and heat treatment. CONSTITUTION: Thermal bonding and molding are performed so that the max. orientation degrees OM, OS on the thermal bonding side and non-thermal bonding side of a polyester biaxially stretched film become OM1, OS1 after bonding and OM2, OS2 after molding and, further, heat treatment is applied so that the max. orientation degrees become OM3, OS3. OM1, OS1, OM2, OS2, OM3 and OS3 satisfy formulae 0.30
