Process for manufacturing stratified profiles, especially, but not exclusively, for the production of packaging, characterized in that a sheet of paper and tissue or other material and a film are rolled or superimposed in several layers, one on top of the other. Of plastic material, this winding or superposition being carried out directly in cold, and without any other contribution, on a shape that presents the dimensions of the profile to be made, this winding or overlapping being, only after its formation and at any time, brought to an enclosure separated at a temperature such that there is fusion of the film of plastic material and, therefore, welding intimately with each other of the various constituent layers.
