摘要:
A controlled permeability film including a film forming polymer and optionally including a dispersing polymer; and an inert porous filler optionally having a surface modifying agent coated thereon, the inert porous filler being present in an amount effective to reduce the ratio of the carbon dioxide permeability to the oxygen permeability of the film, and wherein the filler has a particle size greater than the intrinsic film thickness of the film forming polymer. A composite packaging article and a packaged produce product are also disclosed.
