METHOD OF LAMINATED PACKING MATERIAL PRODUCTION AND PACKING CONTAINERS FORMED OF ABOVE PACKING MATERIAL

摘要

FIELD: packing equipment, particularly of laminated packing materials. ^ SUBSTANCE: method for producing packing material including core layer made of paper or cardboard and gas-barrier layer applied on one core layer side involves forming gas-barrier layer of composition including dispersion or solution of polymer and non-organic flaky material; applying gas-barrier layer on at least one side of carrier layer and drying gas-barrier layer by heating thereof for disperser or solvent removal; connecting carrier layer with gas-barrier layer to one side of core layer. The ready sheet or web material is used for packing container production by folding. ^ EFFECT: improved oxygen impermeability, elimination of excessive moisture absorption by core layer and prevention of crack formation in coated core layer during drying thereof. ^ 26 cl, 12 dwg
