Improved barrier performance with microfibrillated cellulose, TAPPI Journal March 2025
ABSTRACT: In this work, the impact of microfibrillated cellulose (MFC) on the properties of water-based barrier coatings intended for food packaging have been explored. Commercially available MFC was used for improving the rheology and water retention of three different commercially available dispersion coatings (acrylic, styrene acrylic, and polylactic acid). Coatings were applied by rod to paper, and barrier properties were tested by measuring air permeability and water barrier properties. Results clearly showed that addition of MFC to water-based dispersion coatings improved the barrier performance of the final coatings.

Toward environmental resilience in pulp and paper manufacturing: Water consumption and carbon dioxide emission reductions, TAPPI Journal September 2025
ABSTRACT: Pulp and paper manufacturing is a water- and energy-intensive industrial sector, necessitating improvement of its operational efficiency, as well as reduction of emissions to the maximum extent possible. This review focuses on the reduction of water consumption and carbon dioxide (CO2) emissions that originate in the pulp and paper industry (PPI). First, process simulation and optimization techniques used for water consumption reduction are reviewed. Then, techno-economic analyses of solvent-based CO2 capture from PPI are discussed. Additionally, key actions are proposed for enhancing water consumption reduction and CO2 capture in PPI.

Editorial: Advancing barrier science and protective materials: The 2025 winners of TAPPI Journal Best Research Paper Award and Honghi Tran Prize, TAPPI Journal April 2026
At the end of each year, the TAPPI Journal Editorial Board Members nominate papers for consideration as recipient of the Best Research Paper and Honghi Tran Prize from that year, looking for outstanding contributions that push the science and engineering boundaries of fiber-based materials. For 2025, the Board nominated 10 papers and evaluated each nomination in terms of scientific merit, innovation, creativity, and clarity. After voting on the papers earlier this year, the Editorial Board chose two co-winning papers for this distinct honor.
Editorial: Honoring the contributions of Dr. Mahendra Doshi, recycling visionary
In this column, we would like to recognize the contributions to TAPPI and TAPPI Journal made by Dr. Mahendra Doshi, who passed away in April. A long-time member of TAPPI and a TAPPI Journal Editorial Board Member for many years, he is recognized for his research in screening system analysis, wax, and stickies removal in the field of recycling.
Improving barrier performance of coated paper and paperboard using a multi-layer approach
ABSTRACT: Market demand for barrier coated packaging paper and paperboard has been on a steady rise and is forecasted to further increase. As a result, there is a continued interest in improving barrier coating functionalities, which is currently an active area of investigation.

Editorial: Advancing the Digital Twin paradigm — From network mechanics to functional paper physics, TAPPI Journal March 2026
This Special Paper Physics Issue of TAPPI Journal serves as a critical bridge between the phenomenological observations shared at the last International Paper Physics Conference in Wuppertal, Germany, and the rigorous quantification required to realize the “Digital Twin” paradigm. This paradigm involves the creation of a virtual dynamic representation of a process that acts as a real-time counterpart of the actual one. We are particularly indebted to Jaan-Willem Simon of the University of Wuppertal, whose leadership was pivotal in translating the conference’s academic rigor into this scholarly collection.

Development of a packaging test method, TAPPI Journal February 2026
ABSTRACT: Innovation in packaging design will be facilitated by a simple test method to indicate whether a product is compatible with paper recycling. Three laboratories cooperated on the development of a method and used it on linerboard, coated paperboard, wet-strength paperboard, and white copy paper. This test method includes pulping and screening. The data presented here illustrate the factors affecting the results of a bench-scale test. Our observations show that a bench-scale test can give reproducible results for yield, < 5%. We also present an approach to contaminant assessment based on current published test methods. A specification with a lower limit on yield of 70% and a contaminant level of less than 5,000 particles/kg is proposed.

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.

Editorial: TAPPI Journal eBook version offers easy content, TAPPI Journal September 2025
Many readers of TAPPI Journal are familiar with accessing the PDF version of our published research papers, but not all are familiar with the availability and functionality of our eBook version. As opposed to the traditional PDF format, which is a static digital replica of the paper, the eBook version offers a range of additional benefits that make the content more dynamic, accessible, and user-friendly. In addition, you can more easily review all papers in a particular issue much as you could in a print version, as opposed to opening multiple PDFs. Below are some highlights on accessing and making the most of the eBook version.
