Cardboard boxes go through The Edge Crush Test , which in Spanish is the compression test (ECT) , which indicates the amount of compression a box can withstand vertically. It is measured as pounds/inches. This measure is important in warehouses where the boxes are stacked to save space. Remember that the more resistance to pressure, the less risk of crushing the boxes and damaging your product.
Size Limit is the maximum sum of exterior dimensions . This means that the box cannot exceed the stipulated amount.
Gross WR LT is an abbreviation for Gross Weight Limit and means the weight limit allowed inside the box and contents. If it becomes overweight, the box and its contents would be compromised. On the other hand, the seal also informs who the manufacturer of the box is.
