POLYMER FILM, MULTI-LAYER PACKING MATERIAL CONTAINING POLYMER FILM, PACKING CONTAINER FORMED OUT OF MULTI-LAYER PACKING MATERIAL AND PROCEDURE FOR FABRICATING POLYMER FILM

摘要

FIELD: machine building.;SUBSTANCE: packing is made out of multi-layer material containing film, which includes polymer base layer with first and second sides, gas-proof coating out of SiOx applied directly on first side of polymer base layer and thermo-welded olefine polymer layer applied on second side of said polymer base layer. The polymer base layer and the said thermo-welded olefine polymer layer are mono-oriented in the same direction; also total thickness of the said polymer film is 8-40 mcm.;EFFECT: raised proofness for oxygen in all range of humidity and increased durability; improved processability at stage of SiOx coating application, and reduced cost of product.;44 cl, 5 dwg
