Operating methods for a batch commercial metal coil laminating line

Laminating polyester onto metal substrate

The present invention provides for a polymer metallic strip and an improved rapid process for the continuous extrusion coating layer of the surface of a metal strip. The present invention provides for moving a metal strip by a multiplicity of rolls, pre-treating at least one and perhaps both sides of the metal strip using an oxidizing flame, coating layer the pre-treated strip surface(s) with a liquid primer, drying the primer, and activating the primer with an oxidizing flame, and or an oven and/or a corona discharge. The primed, activated, metal strip is then extrusion coated with a polymeric extrudate, passed over a temperature-controlled, chilled roll of a specific surface roughness to achieve the desired surface properties wherein such steps are performed with an edge containment system. The activation and extrusion coating layer steps may be repeated to coat the second side. Further, one may optionally subsequently re-heat the coated strip to about the polymeric melting temperature and follow such reheating with a rapid quench or a stepped surface quench followed by a rapid quench.
