摘要： This method for producing a long stretched film at least involves a step for forming a long film, a step for obliquely stretching the long film, and a step for winding the long stretched film, wherein: it is possible to arbitrarily modify the winding direction of the long stretched film to a direction that obliquely intersects with the direction from which the long film is pulled out; and, in the oblique stretching step, the grip release points of gripping tools that grip both ends of the long stretched film are adjusted such that a grip release line connecting the grip release points on both sides becomes parallel to the widthwise direction of the long stretched film by independently moving the grip release points in the winding direction of the long stretched film. With said method for producing a long stretched film, it is possible to provide a long stretched film having a small variation in the orientation angles in the width direction even when the stretch angle of the long stretched film is modified by changing the pattern of the paths for gripping tool travel support tools.

摘要： Provided are a heat shrinkable polyester film which is excellent in heat shrinkage and can prevent the curling of label terminal part and the generation of wave of label, and a method for preparing heat shrinkable polyester film. A heat shrinkable polyester film has an alignment angle of a molecule chain of 0±10 degrees and a microwave molecular orientation ratio of about 1.29-2.5, wherein the alignment angle of a molecule chain is represented by theta when I(theta) is a maximum value I(theta)max determined by the mathematical formula represented by I(theta) = Io(theta) / [Iav +Q^2W(theta)/Wo(theta) - Wo(theta)/W(theta)^2], and the molecular orientation ratio is determined by the mathematical formula represented by Imax/Imin. In the mathematical formulas, Io is a microwave permeation intensity at a resonance point, Iav is an average microwave permeation intensity according to total rotation angle, Wo is a resonance angle frequency, W is an angle frequency, theta is a rotation angle, Q is Wo/DeltaW (half-width of resonant wave), Imax is the maximum value of microwave permeation intensity, and Imin is the minimum value of microwave permeation intensity.
