Disclosed is a structure comprising a blend of an ethylene-containing polymer, a highly neutralized ethylene acid copolymer, and an organic acid that provides an adjusted oxygen permeability value (OPV). Such structures have improved oxygen permeability and desirable water vapor permeability, moldability, and structural strength, and require breathable films such as meat, fish, sausage, and fresh food in case-ready form. Useful for packaging food. |
