FIBC liner film
The invention relates to plastic film preferably with a thickness of 50 to 300 microns, comprising a polyolefin homopolymer or copolymer, a polyether copolymer having a melting point between 100° C. and 120° C. and a layer comprising oxygen barrier polymer.
1. A plastic film comprising
an inner layer comprising a blend of a polyolefin homopolymer or copolymer and a polyether copolymer having a melting point in the range of 100° C. to 120° C., wherein the inner layer is a layer that comes in direct contact with a product to be packed; and
a layer comprising an oxygen barrier material.
2. The plastic film of claim 1 , where the thickness of the film is between 50 and 300 microns.
3. The plastic film of claim 2 , where the thickness of the film is between 60 and 150 microns.
4. The plastic film of claim 2 , where the oxygen barrier material is ethylene vinyl alcohol (EVOH).
5. The plastic film of claim 2 , where the oxygen barrier material is a polyimide.
6. The plastic film of claim 2 , where the polyolefin homopolymer or copolymer is polyethylene or polypropylene.
7. The plastic film of claim 2 , where the polyolefin homopolymer or copolymer is an ethylene alpha olefin copolymer.
8. The plastic film of claim 2 , where the polyether copolymer is a polyolefin, polyamide or polyester copolymer.
9. The plastic film of claim 2 , where the polyether copolymer is contained in both inner and outer layers.
10. A gusseted tubular film made of a plastic film of claim 2 .
11. The plastic film of claim 1 , where the oxygen barrier material is ethylene vinyl alcohol (EVOH).
12. The plastic film of claim 1 , where the oxygen barrier material is a polyimide.
13. The plastic film of claim 1 , where the polyolefin homopolymer or copolymer is polyethylene or polypropylene.
14. The plastic film of claim 1 , where the polyolefin homopolymer or copolymer is an ethylene alpha olefin copolymer.
15. The plastic film of claim 14 , where the polyether copolymer is a block copolymer.
16. The plastic film of claim 1 , where the polyether copolymer is a polyolefin, polyamide or polyester copolymer.
17. The plastic film of claim 1 , where the polyether copolymer is contained in both inner and outer layers.
18. A gusseted tubular film made of a plastic film of claim 1 .
