FIELD: paper industry. ^ SUBSTANCE: paper with improved rigidity and bulk and method of its manufacturing may be used in pulp and paper industry and are intended for photocopier equipment. Paper comprises three-layer double-tee structure that forms a single web. It has central core layer manufactured mainly from cellulose, bulk of which is increased with the help of filler, such as hydrazine salt. Starch-based coating is applied on both sides of core layer, at the same time starch has high content of solid products. Coating forms three-layer paper having composite structure with outer layers of high strength that surround core of low density. ^ EFFECT: improved strength, rigidity and resistance to twisting of produced material. ^ 32 cl, 2 dwg, 3 tbl, 3 ex |
