PURPOSE:To provide delustered heat shrinkable polyester film, very seldom in defects, such as wrinkle, strain, shrinkage spots and the like which are generated when the film is shrinked by heat, and provided with beautiful finishing appearance. CONSTITUTION:In a delustered heat shrinkable polyester film, the degree of heat shrinkage in a main shrinking direction at 100 deg.C is 40% or more and the same in a direction orthogonal to the main shrinking direction is 20% or less while the degree of heat shrinkage when the film is heated for 10sec employing hot air of 100 deg.C to shrink it 40% by heat in the main shrinking direction of the film and, thereafter, the film is heated by hot air of 130 deg.C for 10sec is 12% or more and the glossiness of the film is 150% or less. |
