Biaxial-orientierte Polyesterfolie zur Verwendung bei der Herstellung von Behältern

摘要

A biaxially oriented polyester film for use in producing containers comprises (1) a polyester containing 93 mol% or more of ethylene terephthalate units as a component, having a breaking elongation in the machine direction (S MD) and a breaking elongation in the transverse direction (S TD) satisfying ÄFormula 1Ü and ÄFormula 2Ü, or (2) a polyester containing 93 mol% or more of ethylene terephthalate units as a component and having a face orientation coefficient of from 0.01 to less than 0.13, or (3) a polyester containing 95 mol% or more of ethylene terephthalate units as a component and having an amorphous Young's modulus of from 120 to 220 kg/mm<2>. Since the film has excellent formability, impact resistance and taste property, it is especially suitable as a film on both the inner and outer faces of metallic cans. $S\; MD:\; Breaking\; elongation\; in\; the\; machine\; direction\; S\; TD:\; Breaking\; elongation\; in\; the\; transverse\; direction$ $$
