Edge Crush Tester – Ensuring Corrugated Box Strength and Durability
.jpg)
Introduction Packaging is more than just a covering—it’s the first shield that protects a product during stacking, handling, shipping, and storage . For industries that depend heavily on corrugated boxes, packaging failure can lead to costly losses and dissatisfied customers. That’s why Edge Crush Testing (ECT) has become an essential quality control step for packaging manufacturers worldwide. At Pacorr Testing Instruments , we manufacture high-precision Edge Crush Testers designed to evaluate the edgewise compressive strength of corrugated fiberboards. Our machines help industries maintain consistency, cut costs, and ensure compliance with international standards. What is an Edge Crush Tester? An Edge Crush Tester is a laboratory testing instrument that measures the load-bearing capacity of corrugated boards when force is applied on their edges. This value directly relates to the box compression strength (BCT) , which determines whether cartons will hold up under vertical...
