Abstract
The invention is directed to a method of producing paper support having a topside and a backside, at least said topside being provided with a pigmented coating based on clay and/or other pigment, and is provided with at least one pigmented polymer resin layer. Adhesion between the polymer resin layer and the pigment coated base paper is improved by applying an activating treatment to the base and exposing the polymer melt to an oxidizing gas prior to extrusion coating, making it possible to perform extrusion coating at higher speed.
Claims14
A method for manufacturing a paper support comprising:
- providing a support having a top side and a back side, at least said topside being provided with a pigmented coating;
- applying an activating treatment to a pigment coated surface of said support;
- providing a polymer melt;
- contacting said polymer melt with an oxidising gas;
- and
- laminating said pigment coated surface of said support with at least one layer of said polymer melt by contacting said support with the side of said melt that has been contacted with said oxidising gas.
Paper support having a topside and a backside, at least said topside being provided with a pigmented coating based on clay or other pigment, which support is provided with at least one pigmented polymer resin layer, wherein an activating treatment has been applied to said pigmented coating and said resin layer has been exposed to an oxidizing gas prior to lamination on said activated pigmented coating.
