Abstract
Disclosed is a heat shrinkable polyester multilayer film having excellent transparency, gloss and workability, which can be produced easily. Specifically disclosed is a heat shrinkable polyester film having a haze value of not more than 2%, a glossiness at a measurement angle of 45° of not less than 200% in at least one side of the film, and a dynamic coefficient friction between one side of the film and the other side of the film of not more than 1.5. The heat shrinkable polyester film also has a shrinkage in the main shrinking direction of not less than 50% when immersed in hot water of 95° C. for 10 seconds and a surface resistivity of not more than 13 log Ω at a relative humidity of 65%.
