Bursting Strength

The Bursting Strength Test is a consistent, reliable and easy-to-use method to define or measure the bursting strength of a paper or paperboard. It is an important measure of quality because it gives an indication of how much pressure a material can resist before breaking or bursting.

The measurement of this parameter is particularly important for materials that will be subject to high pressures, such as packaging applications. The Bursting Strength Tester can be used to measure bursting strength of both flat and corrugated sheets, making it a versatile and essential tool for any testing lab.

Bursting Strength of Paper or Film

The bursting strength of a paper or film is the pressure at which it bursts. The pressure is applied to the paper or film at a right angle using a bulging circular elastic diaphragm. This test is important because it is a measure of the maximum pressure that can be applied to the paper or film. The bursting strength tester is an important tool for quality control because it can precisely measure the bursting strength of a paper or film. This information is essential for ensuring that the paper or film meets high-quality standards.

Quality Control Using Bursting Strength Tester

The Bursting Strength of a paper or film sample is defined as the pressure required to cause rupture. The test is conducted by applying pressure to a bulging elastic diaphragm with a material sample at a right angle. The measure of bursting strength is important for high-quality control in the manufacturing process. By setting and maintaining standards, products can be consistently produced at a high level of quality. The Bursting Strength Tester is an essential tool in any quality control lab.

  3. If you are in the business of paper or corrugated sheet packaging, then you know that the material must be strong and durable. It needs to be able to withstand changes in temperature and pressure, as well as the stress of transportation. But how do you know if your packaging material is up to par? This is where the Bursting Strength Tester comes in.

This quality laboratory testing instrument is widely used to calculate the bursting factor and quality of the corrugated sheets used for packaging. In other words, it will tell you how strong your material is and whether or not it meets the necessary standards. With this information, you can be confident that your packaging will reach the customer without any damage. So, if you want to ensure that your product packaging is world-class, use this highly reliable Bursting Strength Tester.

When it comes to the packaging industry, quality control is of the utmost importance. After all, the products that companies send out to their customers need to arrive in perfect condition. One way to ensure that packages are up to snuff is by measuring their bursting strength.

Bursting strength testing measures the amount of pressure that a material can withstand before it fails. This information is then used to evaluate the quality of the material and determine whether it meets international standards. In other words, by measuring the bursting strength of corrugated material, manufacturers can ensure that their products will stand up to the rigors of shipping and arrive at their destination intact.

Importance of Measuring Bursting Strength.

The importance of measuring the bursting strength of corrugated material cannot be understated. A Bursting Strength Tester is an essential tool for quality control, as it allows manufacturers to evaluate the strength of their products.

Additionally, the bursting strength of corrugated material is an international standard, meaning that it is essential for companies to meet this criterion in order to be competitive in the global market.

By measuring the bursting strength of their products, manufacturers can ensure that they are meeting this important standard and that their products will withstand the rigors of transportation. In short, measuring the bursting strength of corrugated material is essential for quality control and ensuring that products meet international standards.

Testing Bursting Strength

Bursting Strength is an important parameter used to measure the strength of corrugated material. It allows the manufacturer to ensure that the quality of their product meets international standards.

A Bursting Strength Tester applies pressure to a small area of the sample until it ruptures. The amount of pressure required to cause rupture is then recorded. This test is important for quality control, as it ensures that the product will not be damaged during transport. As a result, the measurement of bursting strength is essential for the manufacture of high-quality corrugated packaging.

Measurement of Bursting Strength - Procedure.

The procedure for measurement of Bursting Strength is as follows: A hydraulic load, under a rubber diaphragm of a specific area, is applied to the sample under test. The diaphragm is placed on the baseplate of the instrument and an initial reading is taken.

The procedure is then repeated by reversing the order of the rubber diaphragm and taking second reading. The average of the two readings indicates the bursting factor, which indicates the strength of the paper/ corrugated cardboard/ carton box/ card board under test. This test is useful in quality control to determine the strength of the material.

Key Point for Bursting Strength Test

It is important that the diaphragm area is divided by the hydraulic load to determine the bursting factor, which indicates the strength of the sample. This procedure is used to measure the bursting strength of paper, corrugated cardboard, carton box, card board, leather, cloth, or synthetic leather. This procedure is important for quality control purposes.

Thus, the power required to burst the specimen and procedure is carried out as per specified methods in various standards.  The value so obtained gives an accurate measure of the strength or bursting factor in terms of kPa/m2. This procedure is generally used in Quality Control for paper, corrugated sheets, carton boxes and leather products.

Calculating the Bursting Index

There are many ways to calculate the bursting strength of a material. The most common method is the Mullen test, which involves measuring the force required to burst a specimen. This can be easily done with a simple formula:

How to check the bursting factor or Index?

To check the bursting factor or index, use the formula provided below to calculate them for paper or cardboard.

Burst Factor = Bursting Strength (gf/cm2) / Grammage (grams/m2)  

Burst Index = Bursting Strength (kPa) / Grammage (Kg/m2)

This procedure is often used in quality control to optimize the performance of materials. In some cases, other methods such as the Ball Burst Method may be used. This simply measures the force required to burst a ball that has been placed on top of the material. Whichever method is used, it is important to ensure that accurate measurement are taken in order to obtain accurate results.

Procedure for Measuring Bursting Strength of Plastic films and Packaging materials

There are international standards that have to be followed while measuring the Bursting Strength of a material.

The procedure involves clamping together a polyethylene film specimen placed on the lower probes of the tension measuring device. The upper clamp of the device is brought down at a constant rate until the specimen ruptures. The force required to cause rupture and the increase in sample length due to rupture is measured.

The procedure is carried under standard atmospheric conditions. The results obtained from the procedure are highly repeatable and hence provide reliable data for quality control purposes.

Procedure for Measuring Bursting Strength of Textiles and fabrics.

The procedure for measurement of the Bursting Strength of textile fabrics involves the preparation of a cylinder of the fabric under specified conditions of humidity and tension. The cylinder is then placed on an expanding apparatus and inflated until it bursts. The pressure at which the fabric bursts is then recorded. The results are used to assess the quality of the fabric and to control its manufacturing process. The procedure is simple and quick, and provides a reliable measure of the strength of the fabric.
