Patent ID: 8911839

Claim:
A heat shrinkable polyester laminated film comprising (a) a base film of a polyester resin and (b) a surface layer formed on at least one face of the base film, wherein the surface layer contains (i) colloidal silica with a particle diameter of 1 nm or more and 300 nm or less and (ii) 0.001 to 0.5 g/m 2 of an anionic antistatic agent containing an alkyl group having 10 to 20 carbon atoms, and wherein the heat shrinkable polyester film has a haze value of 2% or less, a glossiness of 200% or more at a measurement angle of 45° for at least one face, a dynamic friction coefficient between one face and the other face of 1.5 or less, a shrinkage ratio of 50% or more in the main shrinkage direction when the film is immersed in hot water at 95° C. for 10 seconds, and a surface resistivity of 13 log Ω or less at a relative humidity of 65%.
