LOW-TEMPERATURE SHRINKABLE FILM

摘要

AN OBJECT OF THE PRESENT INVENTION IS TO PROVIDE A SHRINKABLE FILM EXCELLENT IN DIMENSIONAL STABILITY AT A TEMPERATURE OF 60°C AND HAVING GOOD SHRINK PROPERTIES IN A TEMPERATURE OF 100°C AND 120°C.A LOW-TEMPERATURE SHRINKABLE FILM INCLUDES A FILM COMPOSED OF AT LEAST ONE LAYER INCLUDING AT LEAST ONE ETHYLENE-ALPHA-OLEFIN COPOLYMER (A) WITH A DENSITY OF FROM 0.870 G/CM3 YP 0.920 G/CM3 AND AT LEAST ONE ETHYLENIC COPOLYMER (B) HAVING A MAIN PEAK BELOW 110°C IN THE 2ND FUSION BEHAVIOR OF DIFFERENTIAL SCANNING CALORIMETRY, WHEREIN THE PROPORTION OF THE HEAT OF FUSION AT 100°C OR BELOW TO THE TOTAL HEAT OF FUSION IS FROM 50TO 100IN THE 2ND FUSION BEHAVIOR OF DIFFERENTIAL SCANNING CALORIMETRY FOR ETHYLENE-ALPHA-OLEFIN COPOLYMER (A); THE PROPORTION OF THE HEAT OF FUSION AT 100°C OR BELOW TO THE TOTAL HEAT OF FUSION IS FROM 60TO 100IN THE 2ND FUSION BEHAVIOR OF DIFFERENTIAL SCANNING CALORIMETRY FOR THE FILM; AND THE AVERAGE VALUE OF A HEAT SHRINKAGE PERCENTAGE IN THE LONGITUDINAL DIRECTION AND A HEAT SHRINKAGE PERCENTAGE IN THE LATERAL DIRECTION OF THE FILM IS FROM 0 TO 15AT 60°C, 50OR GREATER AT 100°C AND 70OR GREATER AT 120°C.
