How to Check Bursting Strength of Corrugated Box
Corrugated boxes, also known as cardboard boxes, are widely used in packaging and shipping industries due to their durability and cost-effectiveness. One of the key characteristics that determine the quality of a corrugated box is its bursting strength. Bursting strength refers to the maximum internal pressure that a box can withstand before it bursts open. In this article, we will discuss how to check the bursting strength of a corrugated box.
Understanding Bursting Strength
Bursting strength is an important factor in ensuring that a corrugated box can protect its contents during transportation and storage. It is measured in kilopascals (kPa) or pounds per square inch (psi). The higher the bursting strength, the more robust the box is against external pressure. Checking the bursting strength of a corrugated box is essential to ensure that it meets the required standards and can effectively safeguard the products inside.
Equipment Required
To check the bursting strength of a corrugated box, you will need a bursting strength tester. This device applies pressure to the box until it bursts, measuring the pressure at which the box fails. Some common types of bursting strength testers include the Instron universal testing machine, the MTS machine, and the Instron servo-hydraulic machine. These testers are designed to accurately measure the bursting strength of corrugated boxes and other packaging materials.
Preparation
Before conducting the bursting strength test, it is important to prepare the corrugated box properly. Begin by cutting the box into a standard test specimen, typically a square or rectangular shape. Ensure that the edges are clean and smooth to avoid any irregularities that could affect the test results. The size of the test specimen should be consistent with the specifications of the bursting strength tester you are using.
Conducting the Test
Once the corrugated box is prepared, place the test specimen in the bursting strength tester. The tester will apply pressure to the box, gradually increasing the force until the box bursts. The tester will record the pressure at which the box fails, which is the bursting strength. It is important to conduct multiple tests on different specimens to ensure the accuracy of the results.
Interpreting the Results
After conducting the bursting strength test, compare the results with the required standards or specifications. If the bursting strength of the corrugated box meets the desired criteria, it is considered to be of good quality. If the bursting strength is below the required level, it may indicate that the box is not suitable for the intended application and needs to be improved.
Conclusion
Checking the bursting strength of a corrugated box is a crucial step in ensuring its quality and effectiveness in protecting its contents. By using a bursting strength tester and following the proper procedures, you can accurately measure the bursting strength of a corrugated box and make informed decisions regarding its suitability for specific applications. Regular testing and quality control measures will help maintain the integrity of the packaging process and ensure customer satisfaction.
