Abstract: An elastic film comprising a polymer blend comprising (percent by weight): 1) 50 to 80% of an ethylene polymer composition comprising a recurring unit derived from an ester selected from (1) ethylenically unsaturated organic monomer of esters of unsaturated C3-C20 monocarboxylic acids and C1, to C24 monovalent aliphatic or alicyclic alcohols, and (2) vinyl esters of saturated C2-C18 carboxylic acids, wherein the ester content ranging from 2.5 to 8 wt% based on the total weight of the final ethylene polymer composition; the ethylene polymer composition having a density ranging from 0.920 to 0.935 g/mL; and 2) 20 to 50% of an ethylene-based polymer component having a density ranging from 0.9 to 0.930 g/mL and a melt flow rate up to 4 g/10 min. The film that has a ratio between the MD Elmendorf tear resistance and TD Elmendorf tear resistance of 0.3 or less is suitable for pallet application as banding tape.
