Abstract
This invention relates to a die-cuttable, biaxially stretch-oriented monolayer film comprising a polyethylene having a density of about 0.940 g/cm or less, a propylene polymer or copolymer, or mixtures thereof, wherein the tensile modulus of the film in the machine direction is greater than the tensile modulus in the cross direction, the tensile modulus of the film in the cross direction is about 150,000 psi or less, and the film is free of copolymers of ethylene with an ethylenically unsaturated carboxylic acid or ester. Die-cuttable, stretch-oriented multilayer films also are described comprising the above films as a base layer, and a thermoplastic polymer skin layer bonded to the upper surface of the base layer. The biaxially oriented monolayer and multilayer films are useful in particular in preparing adhesive containing labelstock for use in adhesive labels.
