paper packaging materials, mathematical modeling, hydrophobic composition, polyvinyl alcohol, polyamideamineepichlorhydrin, carbamide, optimal compositionAbstract
The influence of the three-component system parameters of hydrophobic composition (polyvinyl alcohol, polyamideamineepichlorhydrin, carbamide) on the treated paper properties was investigated. Mathematical models of type "composition - properties" were developed, which allow to optimize the hydrophobic composition ratio components and to obtain paper packaging materials with specified properties (air permeability – 10–30 cm3/min, wet-strength – 30–40% and surface absorption – 10–20 g/m2).
