Understanding the Edge Crush Test (ECT) Chart:
An Edge Crush Test (ECT) chart provides a visual representation of the strength of corrugated cardboard against edgewise compression. It is used to determine the load-bearing capacity of packaging materials, especially corrugated boxes. The values on the chart typically indicate the ECT rating (like 32 ECT, 44 ECT), which corresponds to the box’s ability to resist crushing forces during stacking and shipping.
Importance of Using an ECT Chart:
Manufacturers and packaging engineers use the ECT chart to choose the appropriate box strength for specific applications. It helps prevent product damage due to packaging failure and ensures compliance with industry standards. By referring to an edge crush test chart, businesses can optimize material usage, reduce costs, and maintain packaging integrity throughout the supply chain.
