Abstract

PURPOSE:To prepare a thermally shrinkable polyester film which does not shrink spontaneously but shrinks by low-temp. heating, suitable to a shrink label for a container and does not damage an incinerator when burned as a waste material by forming a polyester having a specific glass transition point into a film and then stretching the film. CONSTITUTION:A dicarboxylic acid component contg. 60-90mol% terephthalic acid and 10-40mol% isophthalic acid is reacted with a diol component contg 75-90mol% ethylene glycol and 10-25mol% diethylene glycol to produce a polyester having a glass transition point of 55-80 deg.C. The polyester is formed into a film and is mono- or biaxially stretched longitudinally and/or transversely to give a thermally shrinkable film which shrinks 45-70%, 50-80%, and 70-85% at 70 deg.C, 80 deg.C, and 100 deg.C respectively in the direction of stretching when immersed in glycerin for 30sec.
