Abstract
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 CO2 and low O2 permeability is used to package cheese.
