"PROCESS TO MANUFACTURE COEXTRUDED FROM MULTIPLE LAYERS AND COEXTRUDED MANUFACTURED THROUGH THIS PROCESS". Process for manufacturing a multi-layered extruded material, provided with a layer of plastic material, which presents separation properties in relation to the adhesive substances, the materials generating the separation properties being disposed within the plastic material layer, in which the first co-extruded fabrication is foreseen canvas (2.22), with an adhesive layer (3.23) being applied to one of its sides, over which the plastic material layer (4.24) follows with the separation properties, which in turn is joined to a second canvas (5.25). A coextruded multi-layer is characterized by the fact that at least two plastic sheets (2.5; 22.25) are provided, between which an adhesive layer (3.23) and an additional layer (4.24) with separation properties are arranged. relation to adhesive.
