PURPOSE:To obtain the subject film free from defects of uneven thickness, etc., having excellent low-temperature thermal shrinkage characteristics and mechanical strength and suitable as a shrink label or a shrink package of food, etc., by forming a specific copolymerized polyester in the form of a film and drawing the film. CONSTITUTION:The objective film is produced by drawing a film manufactured from a copolymerized polyester containing (A) 0.5-5mol% of a dimer acid and 95-99.5mol% of terephthalic acid and/or isophthalic acid as dicarboxylic acid components and (B) 5-15mol% of diethylene glycol and 85-95mol% of ethylene glycol and/or tetramethylene glycol as diol components. |
