In extrusion coating and lamination, resin is melted and formed into thin hot film, which is coated onto a moving, flat substrate such as paper, paperboard, metal foil, or plastic film. The coated substrate then passes between a set of counter-rotating rolls, which press the coating onto the substrate to ensure complete contact and adhesion.

Substrates that can be coated with polyolefins include paper, paperboard, biaxially-oriented polypropylene (BOPP), biaxially-oriented nylon (BON), polyester and other plastic films, metal foil, fabrics, glass fiber mat, metal sheet and flexible foams.
