Abstract
A low-temperature heat-shrinkable film having a haze value not larger than 8%, a heat shrinkability in the machine direction at a temperature of 90.degree. C. of at least 30%, and a shrinkage stress of at least 300 g/mm.sup.2, is made from a composition comprising (a) a linear ethylene polymer containing short-chain branches and having a density not larger than 0.940 g/cm.sup.2 and (b) an ethylene/propylene random copolymer containing 3.5 to 10% by weigh of units derived from ethylene, wherein the proportion of the ethylene/propylene random copolymer in the composition is 15 to 50% by weight.
