PROBLEM TO BE SOLVED: To provide a thermoshrinkable polyester-based film for a label of a full bottle, especially for a label of a glass full bottle generating extremely slight wrinkle by shrinking, shrinking unevenness and distortion. SOLUTION: This thermoshrinkable polyester-based film contains 0.1-20 wt.% of a polyester-based elastomer. A hot water shrinkage of the polyester-based film in a principal shrinking direction is 10-50% at 70 deg.C for 5 s and >=75 % at 85 deg.C for 5 s, and in a direction orthogonal to the principal shrinking direction is <=10% at 85 deg.C for 5 s. |
