FIELD: paper industry.
SUBSTANCE: cardboard contains at least two layers: the first layer made of raw materials having high density and high module of elasticity; and the second layer to provide voluminousness for cardboard, in which the second layer contains chemical-thermomechanical pulp (CTMP) of broadleaf wood, cellulose and/or CTMP of coniferous wood at the specified ratio of components. At the same time coherence by Scott is achieved, making at least 80 J/m2; index of bending resistance making at least 5 Nm6/kg3 and strength in direction z, making at least 200 kPa. Invention also relates to products made of cardboard.
EFFECT: expansion of multilayer cardboard range and improvement of its quality.
