Document Type and Number:
Japanese Patent JP4304243
Kind Code:
B2
Abstract:
Heat-shrinkable polyester films, each having: a heat shrinkability of 30-60% after treatment in hot water at 70° C. for 5 seconds and of 65% or higher after treatment in hot water at 85° C. for 5 seconds, both in the main shrinkage direction, and of 10% or lower after treatment in hot water at 85° C. for 5 seconds in a direction perpendicular to the main shrinkage direction; a heat shrinkability after storage at 25° C. for one month of 25% or higher after treatment in hot water at 70° C. for 5 seconds in the main shrinkage direction; and a thickness distribution of 6% or lower, exhibit, when used for full labels on bottles, good shrinkage finish involving only rare occurrence of wrinkles, shrinkage spots, strains and shrinkage failure during heat shrinkage, and exhibit a low decrease in low temperature shrinkability after a lapse of time.
