Do you know how to calculate BS, BF, and BI of papers

 Quality is what attracts customers today. It offers safe, high-quality living for the people. Manufacturers cannot build strong customer bases without paying attention to the quality of their products. People are more concerned about the quality of products these days. A high-quality product is essential for people to have a safe and healthy life. It also helps maintain their standard of living. High-quality packaging materials that protect the product's inner contents at transport and warehousing are the best way to preserve its quality.

The quality of the raw materials used to make packaging containers is one of the most important aspects of packaging materials quality. There are many tests that can be done to ensure the strength and durability of packaging materials. These include the Edge Crush test (Bursting Strength), Edge Crush Test, tearing resistance, tensile, cobb sizing test, tensile tester, drop test and impact test.

What's BS?

BS, or Bursting Strength, is a significant property that explains paper quality. It also reflects other properties like stretching strength, tensile strengths, elongation and many others. Bursting strength (BS), of a paper or board is determined by the amount, type, and quantity of fiber present in the sheet, fiber used at grouting, and the degree of refining that was done at the time sheets were formed.

How is the Bursting Strength of Paper measured?

The strength of many papers can be determined by the bursting strength. It also determines the aptness and level of refinement and beating. BS was developed because it is the oldest method to measure the strength of papers and other paper materials. It is simple to use and can be adjusted to the needs of the user. This practical test is done on corrugated and solid fiberboards. It allows for uniform classification of packaging containers during shipping, transport and warehousing. Different types of paperboard boxes and corrugated boxes can be used to perform the bursting force test.

How do you measure the BS of paperboards

A testing machine Bursting Strength Tester can measure the strength of papers and other related materials. To create pressure on the sample, a sample must be placed between the clamping assembly to create pressure. The rubber diaphragm creates pressure and hydraulic pressure increases at an increasing rate until the sample bursts. The Bursting Strength is the measurement of the pressure at which the material bursts.

Calculation for BS

This is the reading that is displayed on the machine at what pressure the sample burst is called the Bursting Strength.

The unit of measure is one kilogram per square metre. This test is also known as the burst test. High-quality bursting strength testers are used to test the bursting properties of multi-layered papers or paperboards. They have superior diaphragm quality. The test involves putting the sample under pressure until the paper or seal bursts or the box is no longer sealed. Peak pressure testing is also known as the test. It involves applying a force to the samples in order to cause them burst.

Why is BS testing used in Packaging Industry?

This machine is used by the packaging industry to measure the effects on containers of excessive product. Manufacturers use the testing apparatus to make lightweight and decompression boxes in order to offer high-quality packaging material. The quality of packaging products is guaranteed by the manufacturers who purchase high-quality testing machines from reputable manufacturers. These machines are made using advanced technology and high-quality materials.

What is Burst Factor (BF) and Burst Index (BI)?

Apart from calculating the bursting strength of a paper material, the next report which is frequently generated is Bursting Factor and Burst Index.

Both the value of Bursting Factor and Burst Index can be calculated after ascertaining the bursting strength of the materials.

Burst factor = Bursting strength (gf/cm2) / Grammage (gf/m2)

After measuring the Bursting Factor, Burst Index of the paper can be calculated using the formula:

Burst Index = Bursting strength (kPa) / Grammage (gf/m2)

Where,

kPa = kilopascal,

Kgf = kilogram force

Gf = Gram Force

Grammage = Base weight in units of gf/m2.
