Process for the manufacture of a flexible polymeric structure comprising a sealant barrier, consisting of a multilayer film a few microns thick, oriented longitudinally, in a continuous manner, whereby all of the components of said flexible structure are intimately bonded by a final heat treatment. Flexible polymeric structures manufactured according to this process. Application to the fields of the transport of all fluids and protection against external aggressive agents.
