FIELD: pulp-and-paper industry, in particular, production of paper and containers from said paper. ^ SUBSTANCE: paper is made from fibrous material including paper wastes, high-yield semi-finished product, and coat applied in gluing press. Paper includes chemical-thermomechanical pulp used as high-yield semi-finished product and having milling extent of 40-500 Schopper-Riegler. Said pulp is produced by double-staged chemical processing with sodium hydroxide solution and, simultaneously, steaming in screw-type apparatus. Said pulp contains waste paper with milling extent of 50-600 Schopper-Reigler, said materials being used in predetermined ratio. Coat weight is 0.2-2.5 g/m2. Containers using above paper are described. ^ EFFECT: increased rigidity and strength characteristics of paper for corrugation, optimal production costs of paper and containers. ^ 3 cl, 1 tbl, 3 ex |
