ABSTRACT OF THE DISCLOSURE A flexible wrapping material comprising a film laminate i provided for packaging of food products which is resistant to flex-cracking and pinhole development, is impervious to liquids and gasses, and exhibits the property of grease-resistance without the use of adhesives to promote bonds between the layers. The film laminate consists of an outer layer of heat-set, biaxially oriented polymeric material followed by a layer of polymeric material, a layer of oxygen barrier polymer, a layer of biaxially oriented polypropylene, a special grease-resistant polymer, and an inner layer of heat-sealable polymeric material. The film laminate is made by bonding the Outer surface layer of heat-set, biaxially oriented polymer to a substrate in which an oxygen barrier material is carried on a biaxially oriented polypropylene/ special grease-resistant polymer by means of an intermediate layer of polymeric material. A layer of heat-sealable polymeric material is then extrusion-coated on the special polymer surface to form the inner layer of the laminate.
