Process for the manufacture of a laminar material for liquid packaging, consisting essentially of extruding a polyethylene tube or equivalent thermoplastic material, which at the exit of the extrusion die and before its cooling is passed between two rolls to appropriate temperature to maintain the state of semiplastificaciºn in which said tube is, forcing the walls thereof to be applied against each other, welding together to form a single continuous band without continuity between the two walls, whose band is finally cooled naturally or forcibly determining the laminar material.
