How Edge Crush Resistance Test Ensures Packaging Strength

The edge crush resistance test is a vital method used to determine the stacking strength of corrugated boxes. It measures how much pressure the edge of the cardboard can withstand before collapsing. This test ensures the box can handle the rigors of transport and storage without deforming, especially when multiple boxes are stacked. Manufacturers rely on this test to evaluate the durability and reliability of their packaging solutions.

To perform this test accurately, an Edge Crush Resistance Tester is used. This precise lab instrument applies a compressive load on the edge of a corrugated sample and records the maximum force it can bear. The results help manufacturers select the right board grade and maintain packaging integrity, reducing product damage during shipment.
