At least one surface has a dynamic friction coefficient of μd ≤ 0.27 and a range R ≤ 0.05, and the surface is subjected to a load of 400 g by a dye fastness tester with sandpaper having a particle size of # 1000, and before and after 10 round trips. Heat-shrinkable polyester film, characterized in that the weight loss in less than 0.24 g / ㎡. |
