Edge crush testing methods and box compression modeling, TAPPI Journal August 2022
ABSTRACT: While multiple test procedures have been developed to assess the inherent compressive strength of corrugated materials (edge crush test, ECT), limited work has explored the appropriateness of each in the context of box compression modeling. This study incorporates a variety of real-world samples, highlighting the varying challenges different ECT methods face in measuring the intrinsic compressive resistance of combined corrugated board. We examine each of these methods as inputs for different types of models, as well as discuss the propagation of measurement variation through the modeling effort. By highlighting the cases in which a given ECT method no longer proves to be an optimal parameter in box compression strength modeling, we explore how we might better measure this material property.

Wet pressing and product quality: Review of previous pilot machine trials, TAPPI Journal July 2020
ABSTRACT: The purpose of wet pressing is to remove water by mechanical means to consolidate the web and minimize the energy expended in the dryer section. In this process, paper is compacted and densified to degrees that impact end-use performance. Average density is increased by pressing, which has implications for grades where stiffness is important. The z-direction density gradients can affect printing and converting. Lastly, pressing affects surface quality of paper and its response to printing. Broadly speaking, the final press nip dominates the paper surface roughness and the early press nips affect printing performance.

Editorial: A PaperCon preview of what’s coming in April, TAPPI Journal February 2020
Coming soon is PaperCon—TAPPI’s annual technical conference for paper and pack-aging industry professionals. Held this April 26-29 in Atlanta, GA, the conference features sessions on management, coating and graphic arts, process control, recycled paperboard, and a wide range of papermaking topics. Universities and research organizations from around the world are represented in the conference content, and below is a preliminary sampling of just a few of the many presentations that might interest TAPPI Journal readers.
