Perform Edge Crush Test to Determine the Stacking Strength of Corrugated Box

Corrugated boxes are favoured more due to their resistance to damages caused during transit. The boxes guard the products packaged inside from the outside condition. The condition of the package depends on the quality control done by the manufacturers and the transporter as well. To guarantee security, there are many tests performed to ensure better quality and strength of the container. Various quality corrugated boxes are manufactured by different makers of corrugated materials. Therefore, it is important to conduct quality tests on their sheets and boxes.

The increased utilization of fibreboards for transporters has driven the industry to extend. The need to assess the quality of these boards has driven many manufacturers to test the physical qualities of the layered board. New standards are created to determine the true performance and stacking strength of packages for Edge Crush Test (ECT). The result obtained from the test is directly related to the stacking strength of a carton. ECT is a measure of the edgewise compressive strength of a corrugated box. The test can be performed with the help of an instrument known as Edge Crush Tester / Ring Crush Tester / Flat Crush Tester.

The Edge Crush Tester works by compressing a small segment of box or board on its edge. The edges are crushed between the two plates placed at a 90° angle to the direction of flutes. Then the pressure is applied to note down the peak load value. The peak load value is measured to analyse the quality and compressive strength of the corrugated box.

ECT is a reliable method used extensively across many industry verticals to test the quality of corrugated boards and boxes, utilized for packaging products. This ECT value measures the cross-section crushing of corrugated cardboard. Determining the ECT value is important for the boxes and sheets to evaluate the quality to resist crushing forces. The Paper Edge Crush Tester is highly beneficial to test the stacking ability and strength of corrugated materials. It measures the exact resistance and strength of a material and using the data obtained from the test result, the manufacturers can produce boxes, packages, and other products by considering the material’s strength and protective capabilities.

Pacorr offers an Edge Crush Tester used to conduct the edge crush test for the packaging materials to test the crushing forces when applied on a cross-section of the materials. The instrument comprises a movable compression plate responsible for exerting the compressing force. The load cell of the instrument records the force exerted on the sample and as soon as the deflection occurs, the value is noted down.
