Dispersible film

摘要

Bales of unvulcanized rubber, or compounding ingredients for unvulcanized rubber are packaged in film or bags made from an ethylene alpha -olefin copolymer having a Vicat softening point below 90 DEG C. and a melting point below 100 DEG C., and optionally a second ethylene copolymer is added to improve processability of the first ethylene copolymer. The second ethylene copolymer will contain more long-chain branches than the first ethylene copolymer. Such films may be included in a rubber compounding operation.
