a packaging laminate for a container which enables a blend monolayer to be effectively extrusion coated onto the paperboard substrate as the product contact layer without the need for tie layers or multilayer co - extrusion equipment . the blend monolayer has superior oxygen transmission resistance and has excellent pinhole resistance compared to straight polyethylene monolayer . the product contact layer consists of a blend of a polyolefin polymer , a polyamide , and a compatibilizer in a preferred embodiment . the monolayer blend is a low cost alternative to multilayer structures .
