  • Blade-coated paper having a paper lamina produced from a furnish comprising recycled corrugated containers
    Patent number: 5597447
    Abstract: A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 5 by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine. A blade coated paper produced by the method is disclosed.

  • Pulp and paper products produced from recycled, high lignin content, waste paper
    Patent number: 5587048
    Abstract: A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 5% by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine. The pulp and paper produced by the methods are also disclosed.

  • Method for producing a blade coated paper from recycled, high lignin content, waste paper
    Patent number: 5538594
    Abstract: A method is disclosed for producing, in a continuous throughput, high quality paper from recycled waste paper utilizing high consistency, low shear pulping, followed by a series of cleaning steps to produce a wet, friable pulp which is digested and optionally bleached. The resulting pulp can be run on a paper machine alone or blended with virgin pulp to produce a paper containing at least 10% by weight recycled paper with less than 20 ppm per unit area solid non-fibrous contaminants larger than 0.3 mm.sup.2, and which may be blade coated on a high speed paper machine.
