What is the Box Compression Tester ? 

Box compression testers are essential tools for ensuring the quality and durability of packaging materials. By measuring the amount of force that a box can withstand before it collapses, these testers provide accurate and reliable data that manufacturers can use to improve their products and meet industry standards.

The Basics of Box Compression Testing

To perform a box compression testing, a sample box is placed on a flat surface and a compressive force is applied from the top. The force is gradually increased until the box collapses or reaches a predetermined limit. The amount of force required to crush the box is measured in pounds or kilograms, and this value is used to calculate the box’s compression strength.

 

Why Accurate Results are Important

A company that produces fragile electronic components. These components need to be packaged carefully to avoid damage during shipping. The company uses boxes made from a certain type of cardboard that they believe is strong enough to protect the components.

However, the company does not perform regular compression test for corrugated boxes to ensure the strength of the boxes. As a result, some of the components are damaged during shipping, leading to customer complaints, returns, and lost revenue.

Upon investigating the issue, the company discovers that the cardboard boxes they are using have a lower compression strength than they initially thought. If they had performed regular box compression tests, they would have known this and could have chosen a stronger material for their boxes.

In this example, accurate box compression test results could have helped the company avoid costly issues such as customer complaints and returns, as well as identify the need for a stronger packaging material to better protect their products during shipping.

Accurate box compression test results are critical for several reasons. First and foremost, they provide valuable information about the quality and strength of the packaging material being used. Inaccurate test results can lead to products that fail to meet industry standards or that are prone to damage during shipping. This can result in customer complaints, returns, and even legal issues if products are damaged during transit.

By analyzing the test results, manufacturers can identify weaknesses in their packaging materials and make adjustments to improve their strength and durability. This can lead to cost savings in the long run, as well as improved customer satisfaction and loyalty.

 

Factors That Affect Test Results

Several factors can affect the accuracy of box compression test results. These include the type of box being tested, the testing method used, and the condition of the testing equipment. To ensure accurate results, it’s essential to follow industry-standard testing procedures and use well-maintained and calibrated equipment.

1. Compression speed:

The speed at which the box is compressed can impact the test results. If the compression speed is too fast, it can cause inaccurate readings due to the box’s viscoelastic behavior.

2. Temperature and humidity:

The temperature and humidity of the testing environment can affect the material’s properties and, consequently, the test results. Higher temperatures and humidity levels can cause the material to become softer, leading to lower compression strength.

3. Box size and design:

The size and design of the box being tested can impact the results. A larger box may require a higher compression force to reach its breaking point, while a smaller box may break at a lower force. Similarly, a box’s design, such as the presence of flaps or reinforcements, can affect its compression strength.

4. Edge effects:

The edges of the box being tested can be more prone to failure due to manufacturing defects or stress concentration. Edge effects can lead to inconsistent results, making it essential to ensure that the box’s edges are in good condition and uniform.

5. Equipment calibration:

The accuracy of the test results depends on the equipment used to conduct the test. It’s crucial to ensure that the equipment is calibrated correctly, and any potential errors or malfunctions are addressed before conducting the test.

6. Sample size:

The sample size of the boxes being tested can affect the results. Testing a larger sample size can provide a more representative picture of the material’s compression strength.
