LAMINATION / COATING
Extrusion coating is one of the processes used to produce a large range of thin multilayer structures. In the extrusion coating, a molten web of extruded polymer is applied as a thin coating onto a substrate which is passing continuously through a nip-roll assembly (see Figure below).
In extrusion lamination, the molten polymer is applied as an adhesive layer between two substrates to form a laminated structure. The substrate may be paper, paper board, polyester film, polypropylene film, aluminium foil, woven fabric, etc. Please see below a picture of lamination on carpet on a Meaf sheet extrusion line.
Besides the process mentioned above, Meaf does also have solutions available where the lamination takes places in a seperate unit more downstream, for example between the accumulator and the winding system.
