Exploratory study on how sub-ply fiber orientation affects the cracking behavior of wax-based barrier coatings
ABSTRACT: The transition to 100% biobased packaging presents considerable challenges, particularly in the development of a petroleum-free barrier. Generally, biobased barriers exhibit lower flexibility compared to traditional barriers, thereby increasing the risk of cracking during the converting process.
A novel dimensionless index for optimizing the thermo-hydraulic performance of steam condensation in horizontal rotating channels of a multi-channel cylinder dryer
ABSTRACT: The comprehensive performance of steam condensation in horizontal rotating channels, which involves a trade-off between heat transfer enhancement and flow resistance, lacks a unified evaluation criterion. This deficiency is particularly critical for applications such as a multi-channel cylinder dryer (MCD) in paper machines, where rotational operation enhances drying efficiency. To address this gap, this study introduces a novel dimensionless index, W/Eu, defined as the ratio of the dimensionless heat transfer coefficient (W) to the dimensionless pressure drop (Eu), thereby taking into account both heat transfer and flow resistance characteristics comprehensively. A functional relationship for this index was established with respect to channel spacing (Wr) and steam mass flux (G), followed by a theoretical optimization analysis.
Journal articles
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.
Prediction of residual calcium carbonate (CaCO3) in the lime kiln of a kraft pulp mill
ABSTRACT: In a kraft pulp mill, the rotary lime kiln is responsible for converting calcium carbonate (CaCO3) into calcium oxide (CaO) to be reused in the causticizing plant. An important parameter of the calcination efficiency and the product quality is the amount of CaCO3 not converted to CaO, commonly defined as residual carbonate. This parameter is usually determined through laboratory analysis, which introduces delays in process control and limits the ability to make timely operational adjustments.
Aging and degradation of oil and grease barrier papers coated with bio-based starch–wax emulsion
ABSTRACT: The long-term performance and stability of bio-based barrier coatings are critical for sustainable packaging. In this study, the aging and degradation of a biobased starch–wax emulsion coating were examined on two different base papers. Coated samples were stored for 8 months at 23°C and 50% relative humidity (RH) in their original reels to minimize external exposure and isolate internal aging effects. Multiple aging intervals were analyzed using advanced methods to assess both chemical composition and physical structure.
