Zusammenfassung:	Bales of unvulcanized rubber, or compounding ingredients for unvulcanized ru bber are packaged in film or bags made from an ethylene .alpha.-olefin copolymer having a Vicat softening point below 90 .d egree.C and a melting point below 100 .degree.C, and opt ionally a second ethylene copolymer is added to improve processability of the first ethylene copolymer. The second ethylene copolymer will contain mo re long-chain branches than the first ethylene copolymer. Such films may be inc luded in a rubber compounding operation. 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 .degree.C and a melting point below 100 .degree.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.
