Editorial: Coating innovations for driving the next generation of sustainable packaging, TAPPI Journal November 2025

Welcome to the 2025 Special Coating Issue of TAPPI Journal. As we reflect on developments in 2025, the industry’s focus on sustainable packaging continues to sharpen, bringing several critical coating challenges and opportunities into view.

Designing paper and board barrier constructions for food contact applications, TAPPI Journal November 2025

ABSTRACT: This study examines the effect of multiple factors on barrier performance for purpose-built paper and paperboard constructions produced on an industrial pilot coater machine. Impacts from precoat latex chemistry, application method (flooded nip with bevel blade, jet with bevel blade, and pre-metered film coater, laboratory rod drawdown) and precoating calendering were studied in relation to resulting porosity, roughness, and barrier (liquid water, moisture, and oil). Results reveal a complex interaction between controllable and uncontrollable factors, offering insight for designing advanced barrier coatings on cellulosic substrates.

Considerations in managing wastewater odor at pulp and paper operations, TAPPI Journal March 2022

ABSTRACT: Many pulp and paper mills are, at least periodically, faced with the release of odors that can migrate offsite and be considered a nuisance by nearby residents. At chemical pulp mills, perceptible odors associated with reduced sulfur compounds (RSCs) are common, many of which are highly perceptible owing to their low odor thresholds. As releases of RSCs and other odorous substances from production processes are progressively controlled, the proportional contribution from wastewater treatment systems to areal odors can increase. This review paper summarizes important fundamentals of odor generation, source identification, and control. Common odorous substances are identified, and mechanisms for their generation are summarized. Approaches for measuring odorous substances are detailed to enable more effective management, and various odor control strategies are discussed.

Coatings for sustainable paper-based flexible packaging: Barrier properties and processability, TAPPI Journal November 2022

ABSTRACT: In this study, the use of waterborne barrier dispersions from trademarked BLUEWAVE Mechanical Dispersion Technology as thin coatings for paper-based flexible packaging was investigated. Prototypes were designed and examined for their performance in process, rheology, barrier, heat-seal/hot-tack, and coefficient of friction (CoF). Compositional details such as the type and amount of base resins and dispersants were found to significantly impact performances and were key to the development of new prototypes that deliver the performance profiles for implementation in paper-based flexible packaging applications.
