METHOD OF LAMINATING THE FILM TUBE CONTAINING THE INSIGNIFICANT QUANTITY OF PARTICLES Russian patent published in 2012 - IPC B32B27/08 C08J5/18 C09J5/00 C09J5/02 A61M39/08 

FIELD: medicine.

SUBSTANCE: invention relates to the technology of manufacturing of the masked or thermo-laminated flexible film tubes and can be applied to the medicine; the method of their production includes the extrusion of polypropene, copolymer polyethylene, block copolymer styrene- ethene/butylene-styrene, block copolymer styrene-isoprene-styrene and/or thermoplastic elastomer and cooling of the produced tube if necessary; thereafter the film is coated with the functional layer of the copolymer polyethylene and vinyl alcohol, polyvinyl alcohol, polyvinyldichloride, liquid crystalline polymers, SiOx, AlOx or the coating on the base of the acrylate; before coating the film is smeared with the layer of the contact adhesive.

EFFECT: production press is very economical, the functional layer has a very low vapor and gas permeability.
