    • An improved nylon-free recyclable multilayer package and a method for manufacturing the same is provided that addresses the shortcomings of currently available recyclable materials for flexible packaging and containers. One object of embodiments of the present invention will be to provide a flexible plastic package suitable for curbside recycling, for example, a package that may be in compliance with recyclability as defined by the Association of Plastic Recyclers (APR). One such embodiment comprises a package manufactured from a material that is substantially free of nylon. Another or a second embodiment comprises a package manufactured from a material using a certain optimized ratio of compatibilizers in order to achieve suitable packaging performance and standards for recyclability. The flexible recyclable multilayer packaging material comprises a first laminate film and a second laminate film. The first laminate film further comprises, in order: a first sealable polyethylene layer with low initial seal band defining an exterior layer of the first laminate film; a second sealable polyethylene having a certain pre-determined thickness; a first tie layer; a first gas barrier layer of ethylene vinyl alcohol (EVOH); a second tie layer; a second sealable polyethylene layer; and a third sealable polyethylene layer. The second laminate film further comprises, in order: a first sealable polyethylene layer with low initial seal band defining an exterior layer of the second laminate film; a first sealable polyethylene layer having a certain pre-determined thickness; a first tie layer; a first gas barrier layer of ethylene vinyl alcohol (EVOH); a second tie layer; a second sealable polyethylene layer; a third sealable polyethylene layer; and wherein the flexible material is substantially free of nylon.
