FIELD: chemistry.
SUBSTANCE: invention can be used to make medical containers, such as bags for infusions and solution media. The plastic film made by co-extrusion has three layers: a first layer consisting of a polyamide, a second layer containing as the main component a copolymer of an α-olefin and an anhydride monomer of an unsaturated carboxylic or dicarboxylic acid, and a sealing layer having two layers, wherein the external layer contains high-density polyethylene and the internal layer contains a mixture of high-density polyethylene and low-density polyethylene.
EFFECT: invention improves quality properties of the film, speeds up production of bags without damaging the surface of the film and prevents foreign matter from falling into the boundary surface during lamination.
