How Bursting Strength Is Different From Bursting Factor?

Bursting Strength Tester

Corrugated boxes are one of the widely used packaging products that help manufacturers deliver and store products accurately. With so many quality parameters for corrugated boxes, manufacturers can easily test their boxes efficiently so that accurate materials will be delivered to the customers.

Out of these properties, bursting strength means the amount of pressure that a paper can tolerate before it ruptures or collapses. The strength of the packaging materials can be determined by providing air pressure to the board that helps to measure the bursting strength and quality of the corrugated boxes. The best way to judge the bursting strength of the boxes is the bursting strength Tester.

What is the Bursting Factor of Corrugated Boxes?

The bursting Factor is that property which can be calculated after measuring the bursting strength of the boxes. The bursting factor can be calculated by dividing the bursting strength of a board by the basic weight of the paper. This property is expressed in grams per sq. meter.

The bursting factor and bursting strength both help to measure the quality of the corrugated boxes. The better the bursting strength and bursting factor of the paper better its quality. Better quality of Packaging product helps to pack the packaging product safely.

Calculating the bursting factor of packaging materials is crucial for ensuring the integrity and effectiveness of the packaging. The bursting factor is a measure of the strength of a material to withstand pressure, making it a vital parameter in packaging design and selection. By determining the bursting factor, manufacturers and packaging experts can assess the material's ability to withstand external forces during transportation, storage, and handling. With Presto bursting strength tester manufacturers can determine the burst strength of their materials and ensure that accurate quality products will be delivered to the customers.

This calculation is particularly important in industries where the packaged contents are sensitive to pressure or impact, such as in the transportation of fragile goods or perishable items. Understanding the bursting factor allows for the optimization of packaging materials, ensuring they provide adequate protection to the contents within. Moreover, it helps prevent potential damage, breakage, or spoilage during transit, reducing losses for both producers and consumers.

Calculation of bursting factor of cardboard 

Below is the formula for calculating the bursting factor of paper or cardboard: Burst factor=Bursting strength (gf/cm2)/Grammage (gf/m2)

To find the bursting strength of the material, you will require a Bursting Strength Tester. This machine assesses the material's strength, a crucial step in determining both the bursting factor and bursting index.

Now, let us discuss how bursting strength is different from bursting factor.

How bursting strength is different from bursting factor?

Understanding the distinction between bursting strength and bursting factor is key to appreciating their respective roles in evaluating packaging materials. Bursting strength refers to the absolute force or pressure that a material can withstand before rupturing, typically measured in grams per square centimetre (gf/cm²).

On the other hand, the bursting factor takes into account the grammage or weight of the material, providing a more comprehensive assessment by considering strength relative to weight. In essence, the bursting factor is a ratio that helps gauge the efficiency of a material in withstanding pressure based on its grammage.

While bursting strength offers a direct measure of resilience, the bursting factor adds a layer of analysis that considers the material's weight, offering a more nuanced understanding of its performance in real-world applications. Both parameters play crucial roles in determining the overall suitability of packaging materials for specific uses within industries where the integrity of the contents during transportation and storage is paramount.
