Document Type and Number:
Japanese Patent JP6544492
Kind Code:
B2
Abstract:
An object of the present invention is to provide a roll of a white heat-shrinkable polyester-based film containing titanium oxide which can suppress occurrence of a processing trouble of a label or the like cut out from the roll, even when widening the roll. The roll of the white heat-shrinkable polyester-based film satisfies the following requirements: (1) the length of the film is 1000 to 20000 m and the width of the film is 400 to 10000 mm or less; (2) the heat-shrinkage ratio in a main shrinkage direction is 50 to 85%; (3,4) the difference between the maximum and minimum heat-shrinkage ratio in the main shrinkage direction among samples which are sampled in width direction of the film is 0 to 3%, and the difference among samples which are sampled in longitudinal direction of the film is 0 to 3%; and (5,6) the difference between the maximum and minimum apparent specific gravity among samples which are sampled in width direction of the film is 0 to 0.01 g/cm, and the difference among samples which are sampled in longitudinal direction of the film is 0 to 0.010 g/cm.
