Title:
LOW-TEMPERATURE SHRINKABLE FILM
Document Type and Number:
WIPO Patent Application WO/2005/049702
Kind Code:
A1
Abstract:
A shrinkable film having excellent dimensional stability at 60°C and satisfactory shrinkability at 100°C and 120°C. It is a low-temperature shrinkable film comprising at least one layer which comprises at least one ethylene/&agr -olefin copolymer (A) having a density of 0.870 to 0.920 g/cm3 and at least one ethylene copolymer (B) which, in the second melting behavior in an examination with a differential scanning calorimeter, has the main peak at a temperature lower than 110°C, wherein the ethylene/&agr -olefin copolymer (A), in the second melting behavior in an examination with a differential scanning calorimeter, gives a curve in which the proportion of the quantity of heat of fusion in the temperature range up to 100°C to the total quantity of heat of fusion is 50 to 100%, and the film, in the second melting behavior in an examination with a differential scanning calorimeter, gives a curve in which the proportion of the quantity of heat of fusion in the temperature range up to 100°C to the total quantity of heat of fusion is 60 to 100%, the average of the degree of machine-direction thermal shrinkage and that of transverse-direction thermal shrinkage of the film being 0 to 15% at 60°C, 50% or higher at 100°C, and 70% or higher at 120°C.
