The present invention relates to a film material suitable for using in packaging oxygen sensitive products which emit carbon dioxide gas, such as high gassing cheeses. The multilayer film includes at least one layer containing a nylon copolymer, preferably a nylon terpolymer, having at least one aromatic comonomer comprising from about 10% to about 75% by weight of the copolymer. The resultant film material is characterized by a relatively high CO 2 :O 2 transmission ratio; and a CO 2 transmission rate of at least 400 cc/m 2 -day-atmosphere. |
