Influence of base sheet properties on barrier coating performance, TAPPI Journal November 2025

ABSTRACT: Paper packaging offers a sustainable alternative to standard plastic-based materials, particularly for food and beverage applications. With reduced fiber treatment options like fluorochemicals, uncoated base stock often provides little-to-no effective barrier against liquid water, oil/grease, or moisture transmission. Despite the lack of natural barrier performance, base sheet properties can significantly influence the efficiency of applied waterbased barrier coatings. In this study, various base stock properties, such as caliper, porosity, roughness, and ash content, are reported to influence the barrier performance of styrene-acrylic and a copolymer of styrene-butadiene/styrene-acrylate based barrier coatings. These findings will help paper and board producers design better, more cost-effective, purposebuilt substrates for barrier applications in the packaging industry.

Effects of biopolymer coatings on paper permeability and capillarity for paper-based rapid diagnostic test devices, TAPPI Journal September 2025

ABSTRACT: Rapid diagnostic test (RDT) devices are widely used for diagnostics due to their affordability, portability, and user-friendliness. However, conventional assays typically rely on nitrocellulose membranes and plastic casings. These materials raise environmental concerns due to their non-renewable nature, energy-intensive production methods, and poor biodegradability. This study explores the development of fully bio-based RDT substrates using a sustainable alternative: softwoodderived microfibrillated cellulose (MFC), cellulose nanocrystals (CNC), and chitosan as surface modifiers to improve paper properties and enhance RDT sustainability. Cotton filter paper substrates were coated with different biopolymer formulations using a manual blade coater: bleached MFC (BMFC), lignin-containing MFC (LMFC), BMFC combined with CNC, LMFC combined with CNC, and chitosan. Evaluation of the most relevant physical properties concerning RDT performance was conducted, including wetting, water retention value, air permeability, capillary flow rate, and surface morphology. Results showed that biopolymer- based coatings can effectively modify surface properties by reducing pore size and tuning hydrophilicity, while maintaining the renewable and bio-based characteristics of the substrate. The LMFC-coated paper exhibited the best overall performance among all formulations, reducing flow time by 50% (3.00 mm/s vs. 1.5 mm/s) compared to the uncoated paper, yet preserving high water retention. The BMFC+CNC coating also significantly improved flow rate, showing a 36.7% reduction (2.37 mm/s vs. 1.5 mm/s), and enhanced porosity uniformity. In contrast, the flow rate of chitosan-coated paper decreased by over 5,000% (0.027 mm/s), reflecting its strong barrier properties and hydrophobic surface (highest contact angle: 91.4°). These findings suggest that MFC-based coatings are promising ecofriendly alternatives to nitrocellulose, offering optimized capillary transport and structural adaptability. This paves the way for the development of sustainable, high-performance, rapid diagnostic tests.
