Abstract
Described herein are recyclable films with an outer surface comprising a polar polymer, such as polyamide, an inner surface comprising a sealant, and a polar polymer compatibilizer located between the polar polymer and the sealant. Preferably the outer surface is an outer layer of biaxially oriented polyamide and the inner surface is a multilayer inner film comprising the sealant and the compatibilizer.
Claims20
A recyclable film comprising:
- (a) an outer surface of an oriented film comprising a polar polymer,
- (b) an inner surface of an inner film comprising a sealant, and
- (c) a polar polymer compatibilizer layer laminating the oriented film and the inner film,
- wherein the polar polymer compatibilizer layer is a blend of polyethylene and a polar polymer compatibilizer that is a low molecular weight anhydride or carboxylic acid functionalized polyethylene.
1 more element
A recyclable film comprising:
- (a) an oriented outer film comprising at least one polar polymer,
- (b) an inner film comprising a sealant,
- (c) a polar polymer compatibilizer layer laminating the oriented outer film and the inner film, wherein the polar polymer compatibilizer layer is a blend of polyethylene and a polar polymer compatibilizer that is a low molecular weight anhydride or carboxylic acid functionalized polyethylene,
- and
- (d) a barrier layer between the oriented outer film and the inner film, wherein the barrier layer is adjacent to the outer film.
