A packaged article, especially a respiring foodstuff such as cheese which generates or releases gas during storage, and a permeable multilayer biaxially oriented film suitable for allowing escape of such gas while minimizing transfer of oxygen across the film which has a thin layer of a blend of EVOH and nylon. In a preferred embodiment the low cost film having a high permeability to CO.sub.2 and low O.sub.2 permeability is used to package cheese.
[ What is claimed is:] [1.]1. A multilayer cheese packaging film having a thickness of less than 10 mils and comprising a first outer layer;a core layer having a thickness of from about 0.05 to less than 0.10 mils comprising a blend of about 20-70 wt. % of nylon 6/66 copolymer and about 30-80 wt. % of an EVOH copolymer having a melting point of about 158.degree. C. or lower;a protective second outer layer; andfirst and second adhesive layers;wherein said core layer is between said first and second adhesive layers with (1) said first adhesive layer being ...
