<p>PURPOSE: To obtain the subject film excellent in mechanical strength, releasability and dispersibility in ethylene-α-olefin copolymer rubber, and useful for rubber bales, etc., by molding a random copolymer of ethylene and anα- olefin with specific number of carbon atoms. CONSTITUTION: This rubber wrapping film useful for rubber bales, etc., and having the above-mentioned advantages is obtained by incorporating an ethylene-α-olefin random copolymer with 0.01-1.0wt.% of an antiblocking agent and 0.01-1.0wt.% of a slip agent followed by sufficient mixing in a Henschel mixer and then molding the mixture into a film using e.g. an inflation molding machine. The ethylene-α-olefin random copolymer 50-100 deg.C in melting point and 0.1-50g/10min in the MFR at 190 deg.C under a load of 2.16kg is prepared by random copolymerization between ethylene and a 4-20Cα-olefin (e.g. butene-1) at the molar ratio of the ethylene unit to the aα-olefin unit of (80:20) to (95:5).</p> |
