ABSTRACT:
Physical properties of extruded, uniaxially oriented films useful in label manufacture and formed from blends of olefinic base materials and soft polar additives such as ethylene vinyl acetate (EVA) are changed in a directionally selective manner that improves abrasion resistance while preserving conformability by use of compatibilizers or coupling agents in the blends. Machine direction strength properties, including stiffness and tensile modulus, increase with little or no degradation of cross-direction elongation, and with limited degradation of cross-direction tensile modulus, both required for good label conformability.
