FIELD: food industry; packing materials. SUBSTANCE: proposed packing material has layers of polypropylene film, aluminium foil and paper (first version) placed one on the other and connected by binding material, or layer of metallized polypropylene film and paper connected by binding material (second version), Preferable is use of indicated layers featuring the following density characteristics, g/m<SP>2</SP>:: polypropylene film 5-50, aluminium foil 15-300, paper 20-350, binder 1-15 (first version), or metallized polypropylene film 5-50, paper 20-350, binder 1-15 (second version). Such ratios of layer densities provides optimum mechanical strength and hinge barrier properties (moisture and gas impermeability) of packing material and required processing characteristics as tightly glued layers facilitate process of packing of food products. Paraffin, wax or synthetic adhesive can be used as binding material. EFFECT: enhanced quality of food packing, facilitated packing process. 10 cl, 2 dwg, 2 ex
