Wärmeschrumpfbare Polyesterfolien |
摘要 |
Heat-shrinkable polyester films having a heat shrinkability of 30% or more, preferably 40% or more, in the direction of major shrinkage after treatment in hot water at 80 DEG C for 30 seconds, the ratio of heat shrinkability in the direction of major shrinkage after treatment in hot water at 80 DEG C for 5 seconds to heat shrinkability in the direction of major shrinkage after treatment in hot water at 80 DEG C for 30 seconds being 0.8 or less, preferably 0.7 or less. The heat-shrinkable polyester films are suitable for label applications because of their particular heat-shrinkable properties such that not only do they scarcely cause longitudinal sinking when shrunk but also they have very few wrinkles, shrinkage spots and strains remaining after shrinkage. |
