Abstract

Tubular tensioning process of a linear-chain organic thermoplastic material, characterized in that a tube of thermoplastic material without orientation, at a temperature below its melting point is regulated its temperature, to another in which it can be uniformly dilated to guide it biaxially by internal gaseous pressure, and it is dilated and tensed to biaxially orient the linear organic thermoplastic film, and this film is cooled by circumferential air currents and applied uniformly at least on the second half of its expansion zone, in such a way that can be used and a high internal gaseous pressure is used to dilate the tube.
