Claims
- 1. A composition suitable for extruding into a film comprising a linear polyethylene polymer, wherein said linear polyethylene polymer is a member selected from the group consisting of a homopolymer of ethylene and a copolymer of ethylene and a minor amount of a higher olefin containing 4 to 10 carbon atoms; 0.005 to 2 weight percent of a fluorocarbon polymer having a fluorine to carbon ratio of at least 1:2 which is fluid at a temperature of between 120.degree. C. to 300.degree. C.; and 0.01 to 0.5 weight percent of a polyalkylsiloxane consisting essentially of methyl-higher alkyl siloxane in which said higher alkyl contains 6 to 18 carbon atoms.
- 2. The composition of claim 1, wherein said linear polyethylene copolymer has a density of 0.90 to 0.94.
- 3. The composition of claim 1, wherein said linear polyethylene copolymer has a density of 0.90 to 0.94 and said higher olefin is butene.
- 4. The composition of claim 1, wherein said linear polyethylene copolymer has a density of 0.90 to 0.94 and said higher olefin is hexene.
- 5. The composition of claim 1, wherein said linear polyethylene copolymer has a density of 0.90 to 0.94 and said higher olefin is octene.
- 6. The composition of claim 1, wherein said fluorocarbon polymer is polyvinylidene fluoride.
- 7. The composition of claim 1, wherein said fluorocarbon polymer comprises 0.01 to 0.5 weight percent of the composition.
- 8. The composition of claim 2, wherein said fluorocarbon polymer comprises 0.01 to 0.5 weight percent of the composition.
- 9. The composition of claim 6, wherein said fluorocarbon polymer comprises 0.01 to 0.5 weight percent of the composition.
