Extrusion Coating Roller

Extrusion coating is the coating of a molten web of synthetic resin onto a substrate material. It is a versatile coating technique used for the economic application of various plastics, notably polyethylene, onto paperboard, corrugated fiberboard, paper, aluminium foils, cellulose, Non-wovens, or plastic films.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.Extrusion cooking is a multi-functional thermal/mechanical process, which has drawn wide attention in agro-food processing industries. This process has various beneficial effects like destruction of antinutritional factors, gelatinization of starch, increased soluble dietary fiber and reduced lipid oxidation.
