Cardboard is a versatile material that is commonly used in packaging due to its strength, durability, and affordability. It can be used for a wide variety of packaging applications, including shipping boxes, retail packaging, food packaging, and more. Testing the bursting strength of cardboard is an essential part of quality control that will help manufacturers in assessing the resistance of these materials against bursting.

By testing the bursting strength of cardboard boxes, manufacturers can ensure that they are producing high-quality boxes that meet industry standards and customer expectations. It helps to identify any weak spots in the cardboard material and allows manufacturers to make improvements to their manufacturing processes.

Thus, we at Presto being Asia’s top manufacturers of lab testing instruments have designed high-quality laboratory testing equipment known as bursting strength tester.

This digital bursting strength tester has been designed to test the bursting strength of cardboard, liner boards, leather, cloth, or synthetic leather. This quality laboratory testing equipment has been designed as per industrial standards that make it easy for the users to get highly accurate lab testing results.

In this article, we are going to discuss the use of the BS 3137 bursting method in testing the quality of cardboard. So, let us get started!

Why bursting strength is important in the testing quality of cardboard?

The primary purpose of the bursting strength test is to determine the ability of a material to resist failure in the presence of an applied internal hydrostatic pressure. The test is often used to assess the structural integrity of corrugated boards, paperboard, and related materials.

The results of the test are typically reported in terms of the burst strength (expressed in kg/cm2), which is a measure of the amount of force required to cause the failure of the specimen.

With the use of Presto bursting tester, manufacturers of paper and packaging industry can avoid the box bursting problems.

There are several factors that can affect the bursting strength of cardboard, such as the type and weight of the paper, the fluting medium, and the coating. In general, heavier papers and boards will have higher bursting strengths than lighter papers. Coated papers and boards will also tend to have higher bursting strengths than uncoated papers.

The results of bursting strength tests can be used to compare different grades or types of paper or board, to assess manufacturing quality control, or to evaluate material performance under various conditions.

Now, let us discuss more Presto bursting strength tester machine.

Test the bursting strength of cardboard with Presto bursting strength tester

Bursting strength measures the resistance of boxes against bursting when bursting force will be applied to them. This can be tested with the help of a laboratory testing instrument known as a bursting strength tester. Presto is bursting strength tester manufacturer in India at a cost-effective price.

This helps to make cardboard burst-proof and ensures that quality materials will be delivered to the customers.

Presto Digital Bursting Strength Tester is utilized for measuring the bursting strength of paper/strong paper-board by submitting it to an increasing uniform hydraulic pressure. The procedure involves preparing the specimen for test and mounting the sample between two circular clamps.

The specimen is then, tightened with the help of geared handle provided. The increasing pressure (hydraulic) is then applied by the handle. The diaphragm is expanded till the specimen ruptures. The reading on the digital display is the Bursting strength of the given test specimen in kg/cm2. 

This quality testing equipment is widely used in  and provides highly accurate testing results. It has been made with industrial standards including ASTM D3786, BS 3137, ISO 2758, ISO 3303-1:2012, ISO 3689-1983, IS – 1060, 1987. Now, let us discuss the features and technical specifications of this quality testing equipment.
