Kind Code:
A
Abstract:
PURPOSE:To obtain a heat-shrinking polyester film which has good low- temperature shrinking properties and can accomplish uniform shrinkage free from uneven shrinkage by forming a film from a composition comprising two specified polyester resins and stretching this film. CONSTITUTION:A heat-shrinking polyester film obtained by forming a film from a resin composition comprising 95-5wt.% polyester resin containing a dicarboxylic acid component comprising terephthalic acid and a diol component consisting of ethylene glycol and 1,4-cyclohexanedimethanol and 5-95wt.% polyester containing a dicarboxylic acid component comprising at least two members selected from among terephthalic acid, isophthalic acid, phthalic acid, phenylenediacetic acid and an aliphatic dicarboxylic acid and a diol component comprising at least one member selected from among ethylene glycol, propylene glycol, butanediol, neopentyl glycol, diethylene glycol and polyalkylene glycol, and then stretching this formed film.
