FIELD: polymer materials. SUBSTANCE: invention relates to technology of manufacturing plastic sheet wherein plastic is of polyester type. Sheet is obtained by extruding mixture of different polyesters. Laminated material comprises metal substrate and plastic layer, the latter including adhesive layer, which essentially consists of plastic sheet manufactured according to invention. Products obtained from such laminated material, in particular screw covers, crowns, easily opening ends. Laminated material is as well used for manufacturing components wherein plastic layer is covered with polyvinylchloride-containing substances. EFFECT: increased adhesion of polyester to metal even after deformation of metal and wet heat treatment. 28 cl, 3 tbl, 13 ex
