Box Compression Test - A Crucial Evaluation in Packaging Industry

Box compression strength has without mentioning remained a valuable parameter in the packaging industry. It tells the manufacturers about the compressive resistance, stacking ability, and deformation of the finished box. 

What is the corrugated box compression test about?

Among all the packaging testing instruments, there are a few significant instruments that packaging manufacturers cannot afford to go without. The box compression tester is one of those. It is responsible for successfully conducting the box compression test on the finished box. 

A packaging box when stacked for a longer period may change shape or get deformed subjected to continuous weight. To check how long it can bear this load without changing shape is the objective of this test. So, the compression strength of the corrugated box refers to its ability to withstand heavy loads/weights before it deforms or changes shape/size. It is a mandatory parameter in understanding the packaging quality. Packaging manufacturers and those in the distribution chain make use of this valuable test and tester on a regular basis.

How is the box compression test performed?

When it comes to conducting this test, manufacturers rely on UEC’s high-quality box compression tester, that comes with a digital display. An instrument is a microprocessor-based unit that offers memory to retain the peak value, automatic and normal zero settings, and a load and travel protection feature.

To perform the test, the corrugated box sample is pressed under a specific weight for a particular time period. The compression load at which the sample deforms defines its compression strength. The test results, i.e., the compression load and the sample’s deformation, gets displayed on the digital display. 

The test results can be transferred from the unit to the personal computer using MS Windows software. When required to find out the arithmetic mean, maximum and minimum values, and the peak value of the results, data analysis software is provided.
