Corrugated boxes are one of the most commonly used materials in packaging. These boxes will be used in different sorts of applications, such as shipping, packaging, and storage of products efficiently. When these boxes are carried, then they are prone to burst due to rough handling. Thus, it will be important for the manufacturers to test the bursting strength tester for carton box and ensure that the quality material will be delivered. Thus, we at Presto have designed a high quality bursting strength tester digital that has been designed to test the bursting strength of corrugated boxes and other related materials. In this blog, we will discuss brief information about the cause of the bursting of boxes and how you can overcome this challenge by testing it effectively with a bursting strength tester. So, read this blog till the end.

Why are corrugated boxes tested against bursting?

Corrugated boxes are extensively used in packaging due to their strength and durability. In order to ensure that these boxes can withstand the pressures of shipping and handling, they are regularly tested for bursting.

The main reason for the bursting of boxes is rough handling during shipping and storage. Besides this, the grade of paper used for the liner and medium, the fluting, the box design, and the way the box is filled all play a role in determining burst strength. Higher grades of paper result in higher burst strengths. Fluting also plays a role in burst strength. Flutes that are closer together result in higher burst strengths than those that are further apart.

Thus, you can easily test the bursting strength of cardboard with the help of the Presto burst testing machine. Now, let us discuss how Presto bursting strength tester is helpful in testing the bursting strength of corrugated boxes.

How is a Presto bursting strength tester helpful in testing the bursting strength of corrugated boxes?

The bursting strength of a corrugated box is determined by the amount of force required to rupture or burst the faces of the fluting. The test measures the maximum load-bearing capacity of the material before it breaks. Testing the bursting strength of corrugated boxes and other related materials will serve to be important to ensure that the materials delivered will be of high quality.
