HEAT-SHRINKABLE POLYESTER FILM |
摘要 |
<p>Disclosed is a heat-shrinkable polyester film having a specific composition. A heat shrinkage factor of a 10cm square sample of the film in a maximal shrinkage direction of the film is not less than 20% under the condition that the sample is immersed in hot water of 85 DEG C for 10 seconds, and then in water of 25 DEG C for 10 seconds. The number of test pieces of the film having a rupture ratio of not more than 5% is not more than 10% to the total number of the test pieces under the condition that a tensile test of drawing the film in a direction orthogonal to the maximal shrinkage direction of the film is conducted with a distance between corresponding chucks of 100 mm, each test piece having 15 mm in width, a temperature of 23 DEG C, and a drawing rate of 200 mm/min.</p> |
