FIELD: process engineering.
SUBSTANCE: proposed composite comprises, at least, two polymer layers uniformly bonded together. Note here that printed surface with printed layer absorbing visible light is located in and/or on said composite. Absorbing printed layer forms a section of printing while all sections of printing on polymer layer printed surface occupy 50% to 95% of surface area. Note here that said two polymer layers uniformly bonded together are transparent and/or translucent. Besides, either one printed surface with printed layer on composite polymer layer has free section shaped to window and, at least, one said free section has printed info symbol, or, at least, one printed surface with printed layer has free section shaped to window on first polymer layer, and one surface of second polymer layer has printed info symbol visible through, at least, one free section on first polymer layer surface.
EFFECT: higher degree of protection.
