RAW RUBBER LAPPING FILM

摘要

The present invention provides a raw rubber lapping film formed of an ethylene-.alpha.-olefin random copolymer comprising ethylene unit and an .alpha.-olefin unit having 4 to 20 carbon atoms and a raw rubber bale lapped with this film. Since the film is superior in strength and release properties and has good dispersibility in ethylene-.alpha.-olefin copolymer rubber, the operation of lapping raw rubber with a film, the operation of stripping a film from a lapped raw rubber bale and the operation of separating each of a plurality of raw rubber bales are carried out easily and yet there is no adverse effect on the subsequent rubber processing step without stripping the film by heating at a temperature higher than the melting point of the film at the time of kneading.
