Cardboard boxes and packaging are often subjected to various stresses and pressures during shipping, handling, and storage, and their ability to maintain their structural integrity is critical to protecting the contents they contain. A bursting strength tester is used to determine the maximum amount of force that a given sample of cardboard can withstand before it ruptures or bursts. 

The burst strength test is typically performed using a burst strength tester, which applies hydraulic pressure to a sample of the material until it ruptures. The sample is placed between two circular plates and pressure is applied to the top plate, which gradually increases until the material bursts.

By testing the bursting strength of corrugated box , manufacturers and users can ensure that the packaging they use is strong enough to withstand the stresses of transport and storage, and can provide adequate protection for the contents inside. Thus, we at Presto being, Asia’s top lab testing instrument manufacturer have designed high-quality lab testing instruments known as a digital bursting strength tester.

This high-quality laboratory testing instrument will easily measure the force required to completely rupture the material. In this blog, we will discuss briefly how you can easily measure the bursting strength of cardboard. We will also discuss the importance of testing the bursting strength of cardboard and other related materials.

Importance of testing the bursting strength of cardboard

As we have discussed above cardboard is an essential item of packaging. They can widely be used for shipping and handling various types of products, and their ability to maintain their structural integrity is critical to ensuring that the contents inside are protected from damage during transit or storage. Presto is the best bursting strength tester manufacturer in india in 2023.

Here are some of the key reasons why testing the bursting strength of cardboard is important:

  1. Quality control: By testing the bursting strength of cardboard, manufacturers can ensure that their products meet the required quality standards and specifications. This helps to maintain consistency and reliability in their product offerings.
  2. Safety: Cardboard packaging that is not strong enough to withstand the stresses of handling and transportation can fail, potentially causing harm to people or damaging the products they contain. Thus, testing them will help the manufacturers to ensure the safety of the products delivered.
  3. Protection of contents: Cardboard packaging that is too weak can collapse or deform during handling and transportation, resulting in damage or loss of the products inside. Testing the bursting strength helps to ensure that the packaging is strong enough to protect the contents during transit.
  4. Reduce product rejections: Packaging that fails during transport or storage can result in expensive returns, replacements, and customer dissatisfaction. Testing the bursting strength of cardboard can help to reduce the risk of such issues, leading to cost savings for manufacturers and customers.
  5. bursting strength of fabric: refers to the maximum amount of force or pressure that a fabric can withstand before it ruptures or bursts. It is an important measure of a fabric’s strength and durability, and is often used in quality control and testing of fabrics for various applications such as clothing, upholstery, and industrial textiles.
  6. The bursting strength of paper: is influenced by several factors, including the type of fibers used to make the paper, the paper’s thickness, and its surface treatment. Generally, papers made from longer, stronger fibers such as those from hardwood trees have a higher bursting strength than those made from shorter, weaker fibers such as those from softwood trees.

Overall, bursting test is an important quality control measure that helps to ensure the safety and protection of products during transport and storage, while also reducing costs and improving customer satisfaction.

Now, let us discuss a brief about Presto bursting strength tester.

Useful steps to conduct bursting strength test on cardboard

To conduct the bursting strength of the materials, one can easily follow the steps mentioned below: Presto is the bursting strength tester supplier in India

  • Once you prepare and place the specimen accurately on Presto bursting strength tester, press the “Push for burst” button. Make sure you do not release the button until the Sample is burst.
  • The display will give the bursting value.
  • After the specimen is burst, there will be a buzzing sound from the machine and the display will freeze and hold the peak value. Immediately release the Push to the burst button after the Test Specimen burst.
  • Note down the Bursting Strength of the test specimen that is indicated on the Load Indicator.

In this way, you can easily conduct a bursting strength tests on the materials.
