Recycled crosslinked vinyl-alcohol polymer coated films and methods to manufacture the same
Embodiments herein relate to a polyolefin-containing film comprising a solidified form of a melt, the melt comprising at least 1 weight percent shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material and an amount of a compatibilizing agent and/or an un-crosslinking agent configured to un-crosslink the crosslinked vinyl-alcohol in the melt, the polyolefin-containing film having an average dimple count of less than about 50 dimples/4 in 2 , and method of manufacturing the same.
1. A polyolefin-containing film comprising a solidified form of a melt, the melt comprising at least 1 weight percent shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material and an amount of an un-crosslinking agent configured to un-crosslink the crosslinked vinyl-alcohol in the melt, the polyolefin-containing film having an average dimple count of less than about 50 dimples/4 in 2 .
2. The polyolefin-containing film of claim 1 , wherein the polyolefin-containing film has an average dimple count of about 30 dimples/4 in 2 .
3. The polyolefin-containing film of claim 1 , wherein the melt contains at least 5 weight percent of the shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material.
4. The polyolefin-containing film of claim 1 , wherein the compatibilizing agent comprises polyethylene grafted or copolymers that contain ester or acetate groups.
5. The polyolefin-containing film of claim 1 , wherein the un-crosslinking agent comprises water.
6. The polyolefin-containing film of claim 1 , wherein the shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material comprises both water and the compatibilizing agent.
7. The polyolefin-containing film of claim 1 , wherein the melt comprises 1 to 10 parts by weight of the compatibilizing agent and/or 1 to 10 parts by weight of the un-crosslinking agent for 100 parts of the shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material.
8. The polyolefin-containing film of claim 1 , wherein the vinyl-alcohol coated polymer comprises PVOH, EVOH, or blends thereof.
9. The polyolefin-containing film of claim 8 , wherein the EVOH contains 10% ethylene or less.
10. A laminate film comprising the polyolefin-containing film of claim 1 and a metal-containing layer.
11. The polyolefin-containing film of claim 1 , further comprising a compatibilizing agent.
12. A laminate film comprising the polyolefin-containing film of claim 11 and a metal-containing layer.
13. A polyolefin-containing film comprising a solidified form of a melt, the melt comprising at least 1 weight percent shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material and an amount of an un-crosslinking agent configured to un-crosslink the crosslinked vinyl-alcohol in the melt, wherein the polyolefin-containing film does not contain a compatibilizing agent, the polyolefin-containing film having an average dimple count of less than about 50 dimples/4 tn 2 .
14. A polyolefin-containing film comprising a solidified form of a melt, the melt comprising at least 1 weight percent shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material and an amount of an un-crosslinking agent configured to un-crosslink the crosslinked vinyl-alcohol in the melt, the polyolefin-containing film having an average dimple count of less than about 50 dimples/4 in 2 .
15. The polyolefin-containing film of claim 13 , wherein the melt contains at least 5 weight percent of the shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material.
16. A laminate film comprising the polyolefin-containing film of claim 13 and a metal-containing layer.
17. The polyolefin-containing film of claim 14 , wherein the melt contains at least 5 weight percent of the shredded recycled crosslinked vinyl-alcohol polymer coated polyolefin material.
