If you work in the packaging industry, you understand the significance of corrugated boxes as a widely used and secure packaging solution. They are employed across various industries to safely package goods. Given their widespread use, it is essential for manufacturers to test the properties of corrugated boxes before supplying them to packaging companies. It is crucial for Salt Spray Chamber corrugated boxes to possess sufficient strength to ensure product safety during storage and transportation. One important property to measure is the compression strength, which determines the maximum force a corrugated box can withstand.

The most effective way to test the compression strength of boxes is by using a box compression tester, also known as a BCT. This testing equipment applies a load on the top or external surface of the corrugated boxes using compression plates. This helps measure how the products perform under real working conditions, such as storage, warehousing, and stacking during transportation.

How does the testing machine function?

A compression tester compresses the material vertically by applying force from both the top and bottom of the material. A sample is placed between two parallel plates, and the Pacorr’s Box Compression Tester allows for the accurate determination of box compression for various packaging materials.

In this blog, we will provide you with information on how to perform a box compression test accurately and the best practices for conducting a compression test. Let’s begin:

The box compression tester is designed according to national and international standard test methods, ensuring precise test results. The machine features two wide horizontal plates positioned parallel to each other, allowing testing of samples of various sizes. Once the sample is placed between the plates and the test is initiated, the plates gradually approach each other to apply compression force on the sample, measured by a load cell. When the box deforms or ruptures, the machine instantly records the readings and displays the maximum load the box withstood before deforming.

However, when conducting the compression test, it is crucial to follow certain steps to ensure accurate and precise results. Here are a few recommendations:
