What is the need of testing the edge crush strength of corrugated boxes?

Edge compression strength is an important property of the material which determines how much stress is applied to the edges of some materials when they are loaded. The higher the compression strength number, the more stress on a material can be applied before it fractures or breaks. Therefore, it is important for corrugated box manufacturers to test the edge-wise compression strength of boxes with ease. We at Presto being the leading manufacturer of edge crush testers will help paper and packaging manufacturers determine the edge crush strength of corrugated boxes with ease. The digital edge crush tester designed by the experts at Presto is highly helpful in calculating the edge-wise compression strength of materials and lets manufacturers determine the conduct of flat crush, ring crush, and other related quality tests on the materials. Here in this blog, we are going to provide you with brief information about the Presto edge crush tester and why you should conduct quality tests on paper-related products. But first, let us focus on the information about edge crush strength and its importance.
