<p>THE PRESENT INVENTION PROVIDES A RAW RUBBER LAPPING FILM FORMED OF AN ETHYLENE a-OLEFIN RANDOM COPOLYMER COMPRISING ETHYLENE UNIT AND AN a-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 a-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 RAWRUBBER BALES ARE CARRIED OUT EASILY AND YET THERE IS NO ADVERSE EFFECT ON THE SUBSEQUENT RUBBER PROCESSING STEPWITHOUT STRIPPING THE FILM BY HEATING AT A TEMPERATURE HIGHER THAN THE MELTING POINT OF THE FILM AT THE TIME OF KNEADING.</p> |
