METHOD FOR THE PRODUCTION OF LIGHT MULTILAYER FLUID SURFACES FROM 100 DARK PAPER

摘要

The invention relates to a "process for producing bright multi-layered surfaces of 100% dark waste paper pulp", wherein, starting from various materials such as corrugated cardboard, mixed waste paper, paper and cardboard sheets and newspapers and magazines, these are present with their original Weisze and after Successful lightening in multi-layered surfaces, such as two- and multi-ply papers, cartons and cardboard, especially folding carton, testliner, duplex paper, duplex board and cardboard are used. The multi-layered surfaces can be provided with a mineral spread. Thus, the printability is given by all printing processes while ensuring the processing and performance characteristics. The object of the invention is to provide the paper industry with a process for producing bright multi-layered surfaces, according to which they are manufactured without the use of primary pulps made of 100% dark waste paper and ensure processing and service characteristics, those with the use of primary pulps are equivalent.
