Multi-layer transparent polyolefin film for application in shrink labelling

A transparent shrinkable film comprising

• (i) a base layer comprising:
• (a) about 5 to 40 wt % of a propylene homopolymer,
• (b) 0 to about 30 wt % of a hydrogenated hydrocarbon resin having a softening point in the range from about 80.degree. to 125.degree. C., and
• (c) about 30 to 95 wt % of a random ethylenepropylene copolymer,
• wherein all percentages are related to the total weight of the mixture, and
• (ii) a top layer having a melting point lower than the base layer comprising at least one .alpha.-olefin polymer on each side of said base layer,
• wherein said film has (2) a capacity for shrinking of more than 15% at 90.degree. C. and of more than 40% at 120.degree. C., in the transverse direction and, at the same time, a capacity for shrinking of less than 5% at 90.degree. C. and of less than 10% at 120.degree. C., in the longitudinal direction, the percentages being in each case related to the respective linear dimension of the film prior to the shrinking process (2) a modulus of elasticity in the longitudinal direction of more than 1,200 N/mm.sup.2, and a modulus of elasticity in the transverse direction of more than 3,000 N/mm.sup.2 and (3) a tear resistance of more than 50 N/mm.sup.2, in the longitudinal direction and of more than 220 N/mm.sup.2 in the transverse direction.
