At the moment, the pulp and paper industry produces a wide variety of types of paper and board, which can serve as an alternative to plastic packaging products. The main requirement for paper packaging is high strength properties, which include: breaking length, resistance to breaking, bursting and tearing. The required strength properties can be ensured at the stage of refining the semi-finished product from which the paper product will be made by changing the consistency of the pulp. Since the influence of the consistency of the pulp during refining on the strength characteristics of the finished product has not been fully studied, it was of interest to find out how the strength properties of castings change when refining the pulp with a change in concentration.
