The Box compression test measures the compressive strength of packages such as boxes, drums, and cans. It usually provides a plot of deformation vs compressive force.
It is commonly used to evaluate shipping Boxs made of corrugated fiberboard as well as wooden boxes and crates. Industrial and consumer packages other than boxes can also be subjected to compression testing: drum, pail, bottle, tub] etc. Package components are also evaluated for compression resistance.
It is usually a laboratory test involving a special machine, a compression tester, to apply controlled compression on a test specimen. A universal testing machine is sometimes configured to perform a package compression test. Compression testing can also involve a superimposed dead load to a test package.
Fiberboard box can be evaluated by many material test methods including an Edge Crush Test (ECT). There have been efforts to estimate the peak compression strength of a box (usually empty, regular singelwall slotted containers, top-to-bottom) based on various board properties. Some have involved finite element analysis.
This used the board ECT, the MD and CD flexural stiffness, the box perimeter, and the box depth. Simplifications have used a formula involving the board ECT, the board thickness, and the box perimeter. Most estimations do not relate well to other box orientations, box styles, or to filled boxes. Physical testing of filled and closed boxes remains necessary.
The Global Box Compression Tester market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Presto group Box Compression Tester – The carton compression test (CCT) will measure the ability of a carton to withstand pressure from above before deforming.
The carton (or package) is put under pressure by testing apparatus to simulate the weight that cartons stacked at the bottom on pallets in a container or a truck can withstand on top without getting crushed and demonstrates to how much they become deformed, too.
Cardboard with multiple layers of fluting will be stronger than those without, but the compression test gives real data on whether one package will be more resistant to pressure from above when stacked than another.
