FIELD: technological processes.
SUBSTANCE: sheet material for production of article from it contains metal wafer and system of polymer coating fixed to it. Internal layer of coating contains PET and modified PET as layer for adhesion of this system with wafer. As barrier layer coating contains layer that includes PET and PBT. External layer contains PET with non-sticking properties, for prevention of this material sticking to blanking tools at normal working temperatures of industrial blanking. Metal wafer is made of steel, or aluminium, or aluminium alloy. System of coating may be produced by extrusion of single layer or joint extrusion of at least two layers. Coating system may be produced by preliminary production of film and its fastening with wafer.
EFFECT: invention makes it possible to improve quality of drink cans production and to increase their shelf life and preservation of taste properties.
