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.

Guest Editorial: Carrying forward the tradition of fundamental research, TAPPI Journal June 2026

Since its first symposium in 1957, the Fundamental Research Symposium has evolved around fundamental research themes aimed at scientifically understanding papermaking. The symposium is organized by the Fundamental Research Committee (FRC), which is operated by the Fundamental Research Society (FRS). The unique format of the symposium, held at universities such as Oxford and Cambridge where participants stay together, fosters intensive academic exchange and collegial interaction.

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.
