Abstract (en)
[origin: WO2004050353A2] The invention relates to a method for producing a multi-layer biaxially oriented film comprising a layer C consisting of an ethylene-vinyl-alcohol copolymer (EVOH layer) and a respective layer B of a modified polyolefin on either side of said layer, with a layer A of a partially crystalline thermoplastic polyolefin on the surface of each modified polyolefin layer. The film is drawn in the longitudinal direction and then in the transversal direction by means of a tenter frame. The invention is characterised in that the EVOH layer C, the adhesion promoter layers B and layer A are coextruded with an equal width and that the clips of the frame grip all five layers simultaneously and collectively.
