Comparison of the application of polysaccharide-based barrier coatings on paper using film press and spray coating, TAPPI Journal January 2025

The growing demand for sustainable packaging has spurred research into biopolymer-based solutions and their application to paper substrates. This study compares the application of low solids, high viscous aqueous solutions of alginate and chitosan on two different paper substrates using a laboratory film press coater and a purpose-built spray coating unit, with a focus on barrier performance and practical industry considerations. Key parameters investigated are air flow rate, water vapor transmission rate, and grease resistance. Results showed that due to the low solids content of the applied biopolymer solutions, film press coating required a double-layer application for coat weights exceeding 4 g/m², making it less viable for industrial application. In contrast, spray coating allowed for higher application weights in a single step. The barrier properties of spray coated samples, compared to film press coatings, varied with the paper substrate: spray coating performed better on one substrate and worse on the other. Contact angle measurement of the substrates suggested that spray coating is more suitable for a more hydrophilic substrate because of improved surface wetting. The study also identified issues with drying conditions and pinholes affecting the quality of spray coated samples, indicating a need for further research to optimize these parameters.

Formability and load-bearing capacity of multilayered paperboard in three-dimensional forming, TAPPI Journal August 2025

ABSTRACT: The forming of paper-based products presents significant challenges, including maintaining geometric integrity, managing springback, and overcoming instability limits. These arise from the material properties of paper, with its high anisotropy, inhomogeneity, and limited strain. Multilayered paperboard, formed without adhesives, offers a promising solution. By customizing layer composition and orientation, this approach leverages mutual fiber support to enhance forming properties. Experimental and numerical analyses reveal that adhesive-free bonding during deep drawing enhances the material’s formability and load-bearing capacity and reduces anisotropic springback. These innovations enable superior product protection compared to conventional industrial single-layered paperboard of similar thickness. This study demonstrates the advantages of tailored layer configurations for improved geometric precision and stability, providing a pathway for sustainable, high-performance packaging solutions.
