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 polymer is applied as an adhesive layer between two substrates to form a laminated structure. The substrate may be paper, paper board, PE or PP film, aluminium foil, woven fabric, etc. Below is an example of a picture of lamination of TPE on carpet by means of a a MEAF extrusion line.
Besides the process mentioned above, we have solutions available where the lamination takes places in a separate unit as a per of downstream process, for example between the accumulator and the winding system.
