Unlock the potential of flexible films against tearing with tearing strength tester

Gaurav Malhotra

Flexible films are used in a variety of industries from food packaging to medical supplies. These films needed to be tested for their tearing strength, which is why it is important for the product manufacturers to make the use of right lab testing instruments. Presto offers high quality tearing strength tester that is considered to be one of the most important testing equipment to test the tearing strength of fabrics, thermoplastic films, and other similar materials.

It has been designed as per industrial standards that include ASTM D1424-09(2013), ASTM D624-00(2012), ASTM D1776, and ASTM D689. This will ensure accuracy in lab testing results. It comes with a high-quality rugged structure with corrosion resistant main body that makes it easy for the manufacturers to conduct tearing strength tests on the materials. In this blog, we are going to provide you with information about a tearing strength tester and how this quality lab testing instrument will be used to test the tearing ability of materials like flexible packaging films. But before that, we will why flexible packaging films should be tested against their tearing strength.

Why it is important for you to test the tearing strength of thermoplastic films?

As we have discussed above, flexible films are used in a variety of industries to deliver items accurately to customers. Thus, testing the strength and durability of these films is essential to ensure that they will perform well as expected for their intended use.

Flexible films with low tear strength are not ideal for packaging applications, as they are prone to damage and will quickly fail when subjected to any kind of stress or abrasion.

These films can easily be torn, creased, and punctured, which can leave the products inside vulnerable to potential contamination.

Additionally, low tear-strength films often lack the necessary strength and rigidity to protect their contents, leading to a higher likelihood of leakage or breakage during transit. As a result, flexible films of low tear strength should not be used in applications where protection and durability is paramount. Thus, it is important for packaging manufacturers to measure the tearing resistance of flexible packaging films.

We at Presto, Asia’s top manufacturer of lab testing instruments have designed a high-quality tearing strength tester to test the tearing ability of the materials. Now, let us discuss brief information about the Presto tearing strength tester.

Conclusion

The use of a tearing strength tester in flexible film packaging is essential for determining the tear resistance of the material. It measures the force perpendicular to the plane of the plastic films and helps determine the tensile displacement and force of the thin films.

The tear strength is a critical indicator of the durability and integrity of the flexible film packaging and helps ensure that punctures in the fabrics do not propagate easily.

Tearing Strength Tester can help ensure the quality of the flexible film packaging while also reducing costs associated with production and providing flexibility in determining the best material for use in different applications.

Therefore, manufacturers of the packaging industry can make use of this packaging testing instrument to test the integrity of the materials. Presto tearing strength tester has been designed to provide accuracy in testing results every time. We also offer a tearing strength tester prima model, that has been designed with highly advanced features.
