11. A recyclable film comprising a base film, the base film comprising: (3) (5)

a) a first outer layer comprising a polyamide;

b) a compatibilizer layer comprising, i) a polyethylene, polyethylene copolymer or blends thereof, and

ii) a compatibilizer comprising a low molecular weight anhydride or carboxylic acid functionalized polyethylene;

c) a first tie layer located between the first outer layer and the compatibilizer layer;

d) a second outer layer comprising a polyamide; and

e) a second tie layer located between the compatibilizer layer and the second outer layer.
