Extrusion coating is a highly versatile industrial process used to coat a molten web of extruded polymer onto a substrate. In the extrusion coating process, a polymer is melted under heat and pressure in an extruder. The produced extruded hot melt is applied as a thin film coating onto substrate which is continuously passed through nip-roll assembly. The substrate may be paper board, polyester film, BOPP film, aluminium foil, or woven fabric. Extrusion coating is widely used in various industries such as building & construction, automotive, consumer goods, imaging, medical & pharmaceutical, and industrial applications. Extrusion coating includes a variety of applications such as liquid packaging, aseptic drink containers, toothpaste tubes, photographic films, flexible packaging, mill & industrial wrappings, transport packaging, sack linings, envelopes, and medical/hygiene. Extrusion coating helps reduce the emission of VOCs, improved quality, cost reduction, and increased productivity.
