PROBLEM TO BE SOLVED: To provide a heat-shrinkable polyester multilayered film of which the wrinkles, strain, shrink irregularity or the like are extremely suppressed low and which is formed using a polyester resin as a main raw material. SOLUTION: The heat-shrinkable polyester multilayered film is obtained by at least uniaxially stretching a multilayered polyester resin raw sheet of which the storage elastic modulus (E') and loss elastic modulus (E") measured under such a condition that frequency is 10 Hz and a temperature rising speed is 1 deg.C/min by a dynamic viscoelasticity measuring method have values satisfying (E'1)/(E'/h)<=7.0, The peak of (E") is present at 70 deg.C or lower, this peak temperature is set to A, the value of (E') at a temperature of A-5 deg.C is (E'h) and the value of (E') at a temperature of A+5 deg.C is (E'1). |
