Claims
- 1. A film comprising at least two layers, including (1) a first layer consisting essentially of an ionomeric resin and (2) a second layer consisting essentially of (a) an ethylene vinyl acetate copolymer and (b) an alkylene bisoleamide of the formula: R—C(O)—NHC2H4NHC(O)—R wherein R is a C4-C25 saturated or unsaturated hydrocarbon, and wherein the bisoleamide is present in an amount of from about 2000 to about 5000 ppm.
- 2. The film of claim 1 wherein the ethylene vinyl acetate layer has a vinyl acetate content of grater than about 10 wt %.
- 3. The film of claim 2 wherein the ethylene vinyl acetate layer has a vinyl acetate content of from about 10 wt % to about 40 wt %.
- 4. The film of claim 3 wherein the ethylene vinyl acetate layer has a vinyl acetate content of from about 15 wt % to about 40 wt %.
- 5. The film of claim 4 wherein the vinyl acetate layer has a vinyl acetate content of from about 15 wt % to about 33 wt %.
- 6. The film of claim 5 wherein the alkylene bisoleamide is selected from the group consisting of: N,N′-ethylenebisoleamide, N,N′-ethylenebiserucamide, N,N′-diolelyladipamide, and N,N′-dierucyladipamide.
- 7. The film of claim 6 wherein the alkylene bisoleamide is N,N′-ethylenebisoleamide.
- 8. A process for producing a multi-layer film of claim 1 comprising the steps: (i) mixing an alkylene bisoleamide of claim 1 with an ethylene vinyl acetate (EVA) copolymer and (ii) co-extruding the blown film obtained from the EVA copolymer/bisoleamide mixture with at least one layer of an ionomeric resin to obtain the multi-layer film.
- 9. A process for producing a multi-layer film of claim 1 comprising the steps: (i) mixing an alkylene bisoleamide of claim 1 with an ethylene vinyl acetate (EVA) copolymer (ii) extruding the ethylene vinyl acetate/bisoleamide mixture (iii) blowing the extruded ethylene vinyl acetate mixture to obtain a blown film and (iv) laminating or coating the blown film obtained from the EVA copolymer/bisoleamide mixture with at least one layer of an ionomeric resin to obtain the multi-layer film.
- 10. The process of claim 9 wherein the ionomeric resin layer is coated onto the ethylene vinyl acetate blown film layer.
