Abstract (en)
[origin: WO9824834A1] Compounding ingredients for unvulcanized rubber, or bales of unvulcanized rubber are packaged in filler reinforced 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 alpha -olefin copolymer. The second ethylene copolymer will contain more long-chain branches than the first ethylene copolymer. The reinforcing filler is selected from talc, especially talc with a high aspect ratio, silica, or other mineral filler, or carbon black, having a strengthening effect on the film. The film will display relatively high 1 % secant modulus and a relatively high Elmendorf tear, for a film having a low Vicat softening point.
