PURPOSE:To provide the subject film composed of a specific white pigment and a specific copolymerized polyester, having a crystal orientation degree in the direction of film thickness falling within a prescribed range, exhibiting excellent white opacity, processability, impact resistance and heat-resistance and useful for metallic container, etc. CONSTITUTION:The objective film has a crystal orientation degree of 0.2-0.6 in the direction of the film thickness and is composed of a copolymerized polyester having a melting point of 210-245 deg.C and containing white pigment particles such as alumina and titanium dioxide having an average particle diameter of 0.1-2.5mum in an amount of >=1X10<8> particles per 1mm<3> of the resin. The film is preferably laminated to a metal plate and formed in the form of a vessel. |
