Evaluate Tear Resistance of Packaging Materials & Fabrics under Stress with the Tearing Strength Tester

The packaging materials & various other fabrics are used in so many applications for various purposes. The materials used in the rigid & flexible packaging industries like laminations, papers, tapes, corrugated sheets, etc. are not just restricted to a single application. These materials are used in different industries for a lot of purposes than just packaging items. 

Similarly, in the case of fabrics & textiles, they are not just used as clothing but for different purposes which bonds the manufacturer of the product to ensure the ability of the fabric or the textile to withstand stress by its tear resistance.

The testing of these materials not only ensures a good quality product that can be used in various industries but also enhances the user experience of the same, providing maximum consumer satisfaction followed by brand building.

To serve these manufacturers the accurate measures of tear resistance of fabrics & packaging materials the Presto Group offers a highly accurate lab testing instrument called the tearing strength tester.

The instrument is designed with extreme precision to determine the tear resistance of packaging and fabric-related materials, aiding manufacturers in evaluating the performance of these materials under stress and segregating them accordingly.

Let us take a look at how the instrument functions to deliver results with such precision and consistency.  

Functioning Mechanism of the Elmendorf Tearing Strength Tester

The conduction of the tear strength test is an extremely simplistic job to perform which aids manufacturers to quickly grasp the functioning of the instrument and thus perform tasks on an expedited basis.  

Before beginning with the tear strength test it is mandatory for the operator to use a slit cutter in conditioning the specimen. The slit cutter is an additional accessory along with the instrument. The slit cutter carves out a 20mm small slit on the specimen at the stress impact zone to encourage accuracy levels.

Once the specimen is conditioned, it is now time for the operator to position the same at the gripper of the instrument. The specimen must be clamped firmly to ensure that it does not move at the time of the stressful impact from the weight of the pendulum.

The pendulum splits the slit entirely, forcing the specimen to tear into halves at different forces. The instrument is offered in different variants i.e 1600 gm Force, 3200 gm force, and 6400 gm force.

To derive the tear resistance of the specimen, the operator has to use a simple mathematical formula:

Tearing Strength = SW X SR / 100.

Understanding with an example, suppose the SW is 1600 gram force and the SR = 10 so the tearing resistance of the specimen would be:

TS = 10 X 1600 / 100

TS = 160 mega newton

This is how the instrument functions and evaluates the accurate tearing resistance of the specimen.

The tearing strength tester is equipped with certain features that enhance the ease of functioning of the instrument and allow the operator to achieve accurate results within no time.

Features of Elmendorf Tearing Strength Tester

The tearing strength tester is designed as a feature-equipped lab testing instrument to help operators achieve maximum accuracy levels while conducting the tearing strength test with no hassle at all.

The first & foremost feature of the instrument is the functioning mechanism. The instrument operates on a pendulum release mechanism which covers a wide range of measuring ranges and ensures consistency along with precise testing.

The instrument is offered with an option of different weight categories i.e. 1600 gm force, 3200 gm force & 6400 gm force, allowing the operator to conduct tests as per standards.

The instrument is equipped with a robust construction of stainless steel material to avoid any scope of corrosion or rusting over a period of time. This enhances the longevity of the instrument and gains the trust of manufacturers from various industries.

The optional feature that you can gain the advantage of is the additional slit cutter to condition the specimen for accuracy-driven results.  

The tearing strength tester also offers strong grippers that are designed with a rugged surface to ensure that the specimen does not move at all, once clamped firmly by the operator. You can read more on the significance of tensile tests on different materials.

There are numerous questions that arise among the manufacturers from both packaging as well as textile industries regarding the functioning, features & other attributes of the instrument. Let us go through these questions and try to find an answer for them. 

Q&A Regarding Tearing Strength Tester?

Ques. What is the range of the measurement scale associated with the Elmendorf tearing strength tester?

Ans. The measurement scale of the instrument has a range of 0 – 100 percent to assist manufacturers and operators in assessing the tear resistance of the specimen under different measuring standards.

Ques. What are the standards complied with the testing mechanism of the instrument?

Ans. The Presto tear resistance tester has gained the trust of manufacturers all across the industries due to its compliance with so many standards which are:

1. ASTM D 1424-09 (2013)
