Why You Should Conduct a Bursting Strength Test?

Why You Should Conduct a Bursting Strength Test

It is never about the material's high & quality strength. Instead, it is about having the right and appropriate strength that will fulfill the purpose of packaging. In certain applications, a high-strength material is required, whereas, in others, a low-strength material is required for proper tearing. Various corrugated box manufacturers have different needs for corrugated boxes in terms of robustness. The manufacturers need to fulfill the demand of clients in order to retain the orders. Thus, by measuring the bursting strength of corrugated boxes it is easy for you to deliver quality products to the customers. Presto has come up with one of the amazing lab testing equipment known as a bursting strength testerthat will help you to evaluate the bursting strength of corrugated boxes.

Here in this blog, we will discuss why you should conduct the bursting strength of corrugated boxes with ease.

What is the purpose of bursting strength of corrugated boxes?

Corrugated boxes are widely used in the packaging industry. Due to their durability, quality strength, and other related factors these boxes will play a significant role in delivering products accurately to the customers. Thus, testing these boxes accurately is of utmost importance. The bursting factor is one of the major parameters that should be considered while assessing the quality of boxes. Our digital bursting strength tester will not only help to reduce the product rejections but also help you deliver accurate results to the clients.

It has a motor-driven mechanism that increases fluid displacement on the bottom side of the rubber diaphragm at a predetermined pace. This simply means that the pressure will automatically decrease and the engine will turn off after the test is done. With this trouble-free corrugated box quality assurance test, you'll be able to determine how long your product will survive once it's dispatched.

The PRESTO® Bursting Strength Tester is perfect for determining the bursting strength of a different range of materials in order to evaluate the failure caused by a hydrostatic force delivered at a continuously rising rate through a rubber diaphragm. It comes with a rugged structure and single-push operation to make sure that you can easily determine this strength and improve the quality of corrugated boxes with ease. You can also read the relation between this bursting strength of cardboard boxes with a number of ply.

Let’s focus on its features and technical specifications.

Features of Presto bursting strength tester

This bursting strength tester plays a major role in the paper and packaging industry and helps to measure the strength of these boxes with ease. Thus, to make sure that these boxes will be delivered without any errors, it is important for you to test the bursting strength of these boxes. Below we have listed the advanced features of this lab testing equipment.

Bursting strength tester is one of the effective lab testing equipment that will help you to check the quality of corrugated boxes with ease. Not all boxes are created equal in terms of strength and durability. They also differ in terms of compression resistance and material thickness. They must pass some of the essential quality tests to deliver accurate results to the customers. The Mullen Test is another name for the burst strength test. This test determines how well-corrugated box walls stay together under extreme pressure. The package specimen is held between clamps of this lab testing instrument. With the help of this test, it will be easy for you to determine the maximum load a package can bear before succumbing to pressure.

We at Presto are considered to be the leading bursting strength tester manufacturer in India and provide the best price for our testing instrument. You can give us a call at +91 9210903903 or email us at info@prestogroup.com to know about the bursting strength tester price.
