1. A recyclable bag for packaging flowable materials comprising a recyclable metallized barrier co-extruded multi-layer polymeric film and a non-barrier co-extruded multi-layer polymeric film, wherein the metallized barrier co-extruded multi-layer polymeric film comprises:
(i) an inner sealant layer comprising an ethylene/α-olefin interpolymer fraction having a density in the range of 0.894 to 0.924 g/cm3 in an amount of at least about 40-50% by weight or thickness of the total inner sealant layer;
(ii) a core barrier layer comprising ethylene-vinyl alcohol (EVOH) comprising about 0.1% to about 10% by total weight or thickness of the co-extruded multi-layer polymeric film, wherein the EVOH comprises from about 27-55% ethylene in the EVOH copolymer; and
(iii) an outer metallized sealant layer comprising a polyethylene, or a copolymer or an ethylene/α-olefin interpolymer fraction having a density in the range of 0.894 to 0.935 g/cm3 in an amount of at least about 40-50% by weight or thickness of the total outer metallized sealant layer, and an ethylene vinyl acetate (EVA) resin.
