Corrugated boxes are one of the most commonly used packaging products that are often found in warehouses, retail stores, and shipping centers. However, not many people know how to test their strengths. The compression strength of a corrugated box can be tested by using a Testronix Box Compression Tester. This is one of the best testing instruments from Testronix that will help you to test your box compression strength with ease. A box can be considered strong if it has high compression strength. The higher the compression strength, the more likely it happens that a corrugated box will withstand. It will not collapse when stacked with other boxes. Thus, if you want to make sure that you deliver the best packaging material, then we suggest you go with this testing machine. Here in this blog, we are going to provide you with 4 crucial steps that you can take to test the corrugated boxes.

What is a Testronix box compression tester?

Corrugated boxes are one of the major means of packaging that are used for safe packaging and transit of various materials and products in different industries. Thus, it is important to test its box compression strength to make sure that the products delivered should not get damaged in transit. Testronix is a leading manufacturer of various testing instruments that helps to improve the quality of your products. One of the most used testing instruments is the box compression tester. It will make sure that the packages are tested in more reliable ways to determine their strength. There are various models of box compression tester available with Testronix Testing Instruments. You can easily see the list below:

  • Box compression tester-computerized
  • Box compression tester-digital

With the help of the Testronix Box Compression Tester, the compression Strength can be easily calculated.

This instrument helps in acting like an index of the overall quality of the material and the compression capacity of the box. These models are made in accordance with various testing standards like ASTM D642, ASTM D4169, TAPPI T804, ISO 12048, and JIS Z0212.

How to test your corrugated box with a box compression tester?

When it comes to corrugated boxes, the strength of the box is paramount. The compression test is a measure of how strong your product will be when transported in a corrugated box. It tests the ability of an object to resist being crushed. Corrugated boxes need to be able to withstand heavy loads and high compressive forces without breaking or bending under pressure. This test determines if your cardboard packaging will last long enough for you to recoup on your investment before it needs replacing again due to structural failure after several shipments. To test the compression strength of boxes with the help of Testronix, a box compression tester, you can follow these 4 crucial steps.

  1. Prepare the specimen, by taking a corrugated box and closing all its sides properly. You can do this by applying the tapes firmly on their sides to fasten them.
  2. Plug the machine in 15 amp, 220 volts AC, and turn the machine on. After that, you should place your specimen in the center of the plate otherwise the test results would not be correct. Mark points are provided.
  3. Bring the compression plate near the specimen by moving the rotary switch in a downward direction. Users can make use of the fast runner option to take the compression plate just above the test specimen with an increased speed of 50 mm/min.
  4. Apply a preload of 1 or 2 kgf on the specimen to remove any air gap between the compression plate and the specimen. After that commence the test.

In this way, you can easily take the test and know the box compression strength of corrugated boxes.
