Abstract A tubular article formed of multilayer differentially cross-linked heat sealable film suitable for the manufacture of bags used in the packaging of meats. The multilayer film contains at least two layers the inner of which is a heat sealable layer containing an antioxidant cross-linking inhibitor in an amount sufficient to inhibit the cross-linking of that layer by irradiation. Accordingly, upon exposure of the multilayer film to radiation, the outer layer will be cross-linked to a greater extent than the first heat sealable layer.
