ABSTRACT:
The ethylene/pentene-1 copolymer composition of the present invention comprises an ethylene/pentene-1 copolymer satisfying specific requests, and a high-pressure polyethylene, polyethylene having a density of greater than 0.935 or low crystalline .alpha.-olefin random copolymer. This composition is excellent in transparency, moldability, heat sealing property at low temperature and tear property, and are particularly useful for packaging film material.
