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.

Evaluating hardness and the S-test, TAPPI Journal March 2019
ABSTRACT: The corrugated industry typically quantifies crush resistance using the Concora corrugated medium test (CMT) on fluted medium or flat crush on combined board. These tests compress the materials until the point of complete failure of the flutes. Combined board elastically resists crushing forces until a certain point, the hardness of the structure, while additional load causes permanent damage and deformation. This study investigates how hardness can be measured directly from a load curve collected during CMT (or flat crush) testing and how it varies throughout the North American paper supply. It also explores how hardness corre-lates with the values obtained from the newly developed S-test. This new test method deserves further study as a potentially more appropriate specification for crush resistance of corrugated medium.

Historical perspectives of corrugated box testing for 2020, TAPPI Journal March 2020
ABSTRACT: In the age of e-commerce, corrugated packaging is experiencing a resurgence; at least, consumers are receiving more corrugated boxes today than ever before. The corrugated box has been the main package for transporting goods for over 100 years, and corrugated board and boxes have been the focus of scientific study for about as long. For the last 50 years, box compressive test strength value (BCT) has been the main focus of research and testing. That was not always the case. In addition, many of today’s boxes experience a different end-use life than their predecessors.

Influence of pallet pattern on top-to-bottom compression performance of unitized loads, TAPPI Journal
ABSTRACT: Environmental scaling factors estimate a corrugated container’s ability to withstand various conditions it will encounter during the storage and distribution process. In this project, we examined the compressive resistance of unitized loads using differing pallet stacking patterns. To simulate real-world failure scenarios in our laboratory tests, we used two different nominal board grades of single-wall C-flute regular slotted containers loaded with a plywood panel and bagged salt to direct the failure location to the bottom of the stack. Our results showed that the columnar aligned pattern provided the greatest compressive resistance and the interlocked stacking arrangement yielded the lowest of the patterns evaluated. Based on the study results, we calculated box compression retention multipliers for each pattern and compared them to scaling factors published by the Fibre Box Association.
