Maximize packaging durability with the edge crush test

The Edge Crush Test (ECT) is a vital packaging assessment used to measure the stacking strength of corrugated boxes. It determines the ability of cardboard to resist crushing at its edges—where it's most vulnerable during shipping and handling. This test is essential for manufacturers to ensure boxes can withstand vertical pressure without collapsing, protecting the product inside throughout transit. By using an edge crush tester, companies can select the right board grade for specific load requirements, reducing packaging failures and customer complaints. ECT results guide design improvements and help optimize material usage, balancing performance with cost-efficiency. Whether you’re in e-commerce, FMCG, or logistics, implementing edge crush testing safeguards your packaging reliability and enhances brand trust.
