To ensure the structural integrity of Corrugated Board packaging, specific quality tests must be made mandatory in technical specifications. The most critical tests are the Edge Crush Test (ECT) and the Bursting Strength Test. These tests quantify the board’s ability to withstand forces essential for safe transit and storage.

The Edge Crush Test (ECT) is a particularly reliable indicator for determining the maximum allowable stacking weight a carton can safely handle during warehousing. Specifying and testing to these standards prevents the costly risk of using board with insufficient structural capability, ensuring product protection throughout the entire supply chain.
