“…The use of paper-based packaging materials is explainned by their ecological safety and minimal impact on the environment, their ability to provide the required level of barrier properties, and the possibility of reusing their waste as a valuable raw material for the production of new products. The development of the paper packaging production requires the use of new materials and their compositions to ensure the preservation of the consumer properties of packaged products from the effects of the environment [1][2][3][4].…”

“…This article is based on the results of previous studies [5; 8; 17], where it was determined that the most effective fibrous raw material for the production of base paper is sulfate-bleached and unbleached cellulose from coniferous wood species at the optimal degree of grinding of cellulose fibers 65-75° SR. Also, the effectiveness of using PVA in a composition with PAE and glycerol for the formation of barrier and protective properties of paper has been tested and proven [18].…”

Introduction. A high level of barrier and protective properties, resistance to moisture penetration (water, steam) and air resistance are the main requirements for packaging paper for food products. Problem. Polyvinyl alcohol-based polymer coatings are widely used for packaging paper; however, such coatings tend to have poor water resistance due to the hydrophilic and water-soluble nature of polyvinyl alcohol. Polyamide-epichlorohydrin resins are used to provide moisture resistance of the paper, and glycerol is used for the elasticity of the coating. At the same time, the complex effect of these components in the mixture for surface treatment of paper on the quality of the products has not been sufficiently investigated. Methods. Compositions based on aqueous solutions of polyvinyl alcohol brand 7/18 of the highest grade, polyamideamineepichlorhydrin EKA WS 325 and glycerol brand PK-94 were used to obtain a moisture-resistant, waterproof and fat-proof packaging material. Polyacrylamide in the amount of 0.25 wt. % was used as a functional additive, a viscosity regulator of the composition, and water was used as a solvent. Model compositions with different ratios of the main components in accordance with the central composite rotatable plan of the experiment were applied to the tests according to the methods adopted in the pulp and paper industry. STAT-SENS software was used for mathematical processing of the experimental results. A multi-criteria optimization method was used to find the optimal range of parameters of the hydrooleophobic composition. Results. The 15 model compositions have been developed. The influencing factors were the content of the polyvinyl alcohol, polyamideamineepichlorhydrin, glycerol. The quality indicators of the treated paper-base were selected as the response functions of mathematical models: oil permeability, air permeability, destructive force, moisture resistance, surface absorption. Conclusions. The developed composition is optimal and makes it possible not to exceed its consumption during application to fibrous material, in particular paper. The composition penetrates the thickness of the paper to an optimal depth evenly over the entire surface of the paper, which makes it possible to provide the paper with uniform barrier properties, mechanical strength and wet-strength along the plane of the canvas. In addition, glycerol gives elasticity to the resulting coating and prevents it from cracking during repeated bending.
