Nowadays, the products of domestic enterprises of the pulp and paper industry are 80% made from secondary raw materials \u2013 recycling paper, which negatively affects its quality, narrows the range and limits the scope of use. This state of the industry connected with the lack of domestic production of cellulose fibrous products. The raw material problem of the pulp and paper industry of Ukraine can be solved by using annual plants and wastes of crop processing for the production of fibrous materials for various purposes. Rapeseed stalks can be considered as a promising raw material to meet the needs of the pulp and paper industry. The aim of the work is to study the physical and mechanical properties of writing paper and cardboard for flat layers of corrugated cardboard, which contain cellulose fibers of rapeseed stalks. This paper presents the results of research of sizes of elementary cellulose fibers from rapeseed stalks. Studies of the fractional composition showed that 70% of cellulose fibers from rapeseed have a length in the range of 0.02 to 0.81 mm and only 30% have a length exceeding 1 mm. To study the effect of cellulose content from rapeseed stalks in the composition of writing paper, paper samples of 80 g\/m2<\/sup> were prepared at different ratios of cellulose from non-wood raw materials to coniferous cellulose. Studies have shown that the surface of paper made of non-wood pulp has a high smoothness and uniform lumen and is more elastic compared to paper made of bleached coniferous sulfate pulp. According to the results of physical and mechanical tests, it can be concluded that the increase in the content of non-wood pulp from rapeseed stalks in the composition of writing paper leads to a decrease in all physical and mechanical properties of the paper. To study the effect of non-wood pulp from rapeseed stalks in a cardboard composition for flat layers of corrugated cardboard, cardboard samples of 175 g\/m2<\/sup> were made. Recycling paper of MS-6B was used as a bottom layer, and non-wood pulp as a surface layer of cardboard. The ratio of recycling paper to non-wood pulp in laboratory samples of cardboard was 80:20 mass %. According to the results, it can be concluded that the use for the surface layer of non-wood pulp from rapeseed stalks allows to obtain cardboard with strength values that fully meet the requirements for cardboard of K-1 type. In general, it was shown that non-wood rapeseed pulp can be used to replace more expensive sulfate bleached coniferous pulp in the production of writing paper and cardboard for flat layers of corrugated cardboard as a surface layer.
