FIELD: technological processes. ^ SUBSTANCE: invention is related to technology for production of biodegradable flaky paper-based materials, in particular to containers for liquid or hard, hot or cooled food products. Biodegradable flaky material contains paper base, having the first and second layers of polyethers applied at least on single surface of base. Intermediate layers of polymers between surface of base and copolyethers applied on base surface are actually unavailable. Copolyethers of both layers are non-identical products of copolymerisation of benzol-1,4-dicarboxylic acid with aliphatic diatomic spirit and at least one reagent selected from group including aliphatic dicarboxylic acid, cyclic diatomic spirit, aromatic diatomic spirit. ^ EFFECT: production of moulded product with improved technical characteristics resistant to damage and softening. ^ 27 cl, 4 dwg, 1 ex |
