Zusammenfassung:	A tube and a method of constructing such a tube, the tube being in the form of a composite film structure comprising a co-extrusion of a plurality of layers bonded together to provide an integrated structure. The layers comprise an inner layer, an intermediate layer and outer layer. The intermediate layer is of a material compatible with two adjacent layers between which it is interposed, wherein the intermediate layer provides a bridge between the two layers to provide the tube as an integrated structure. The exterior surface of the tube is optionally treated or modified or is provided with a coating, typically for bonding with another substance such as a resinous binder. A hollow structure in the form of a tubular element configured as a pipe and constructed using the tube is also disclosed.
