Are you tired of unreliable peel testers that produce inconsistent results? Presto's latest and advanced peel testing instrument has been designed to test the peel ability of materials including:

1.       Adhesives

2.       PSA tapes

3.       Labels

4.       Protective Films

5.       Sealants

Testing these products against peeling strength will not only help to ensure the quality of materials but also let manufacturers avoid any uncertain circumstances that occur due to poor peel strength. You can easily perform a peel strength test on the materials with the help of this quality lab testing instrument.

Here in this blog, we will provide you with detailed information about peel strength testers that will help you conduct adhesive peel strength tests on the materials with ease.

Comprehensive guide to selecting the right peel strength tester

The correct selection of the quality of the peel strength tester ensures more precise and trusted adhesion testing. This high-quality lab testing instrument can easily be used in different industries including the paper & packaging industry.

Below we have listed some points that indicate how you can easily select the right peel strength tester for your laboratory testing needs.

·         Measurement Range and Accuracy

Select a tester with an appropriate force measurement range for your materials. Consider the accuracy and resolution of the measurements, especially for sensitive or critical applications.

·         Peel Angle and Speed

Whenever you select the peel strength tester, then it is important to consider the peeling angle that the machine can offer (90 degrees and 180 degrees) so that it can easily match your testing requirements.

·         Identify the Material and Application Needs

You can consider the materials that you want to test which may include adhesives, tapes, laminates, and films. If your peel tester will be able to test the quality of these materials against peeling force, then you can opt for the peel tester. Presto peel testing instrument has been designed to accurately test the peel/seal/ and bond strength of the materials and ensure that accurate products will be delivered to the customers.

·         Easily usable

Go for the peel strength tester that can easily be usable and comes with user-friendly user interface.

These are some pointers that you should keep in mind while selecting the peel-strength tester for your laboratory testing needs. Now, let us discuss the purpose of performing a peel strength test.

Purpose of performing peel strength test on adhesives

The main goal of peel testing is to ensure that 

  • The adhesive bond between two materials will not give out under the presence of external factors, thus preventing product failures, recalls, and loss of reputation for the companies.

  • Moreover, with peel strength testing, manufacturers can evaluate their production process to make proper changes for better quality assurance. Besides this, the peel strength test helps ensure good quality by establishing any possible improvement in the manufacturing process. 

  • Conversely, in the packaging industry, peel tests that are meant to check on the seals for packages made of pouches, bottles, bags and cartons are necessary.

Leakage of products or contamination through such weak seals during transportation and storage is often reported. Therefore, precise peel tests are necessary to maintain high-quality standards in the packaging industry.

Important steps for performing peel strength tests on the materials

A Peel tester is designed to assess the peel, seal, bond, or adhesion strength of materials in flexible paper and packaging industries. Here are some of the essential steps that you must follow to perform a peel strength test on the materials.

1.       Sample size requirement: 15mm wide and 150mm long.

2.       Conditioning of specimen: Dip into toluene chemical up to 25mm depth for 15-20 minutes to induce anti-adhesion properties.

3.       Fixation of specimen ends into rugged grippers of the tester.

4.       Fixation angles: 180° and 90° as per manufacturer's requirement.

5.       Grippers: The upper jaw remains stationary while the lower jaw moves downward, exerting a pull force to peel the specimen.

6.       Gripper range: Can be as close as 25mm and separated up to 300mm to accommodate flexible materials.

7.       Automatic stop of gripper separation upon complete peeling, regulated by limit switches.

8.       Results indicated on the microprocessor-based electrical control panel.

These are some of the essential steps to perform a peel strength test on the materials. You can read more on how you can easily perform peel strength tests on the materials with the help of this high-quality laboratory testing instrument.

3 common problems solved by peel strength tester

1. Quality Assurance: Peel strength testers may reveal weak adhesive bonds or improper sealing in packaging, labels, or laminates. If this is done early in the manufacturing process, variance or defects can be corrected to ensure that the product meets the necessary quality standard—a very important element today, where costly recalls or customer dissatisfaction is almost entirely due to package failures.

2. Process Optimization: Peel strength testers help optimise the adhesive formulations and application techniques, as well as the parameters of the process used. By conducting systematic peel strength tests, companies are helped to fine-tune manufacturing processes in order to reach optimised adhesiveness levels, minimise waste of materials, and boost production efficiency.

3. Peel strength tester participates in product development and the introduction of new products. By analysing how the new materials perform, as well as adhesives or packaging designs, it can be used to test them. New materials can be tested using a peel strength tester for their adhesiveness with each other or with the surface. The process involves putting some given force on the material until it breaks apart. Researchers and engineers determine the peel strength of an experimental sample or prototype thus finding out those solutions which do not work well. Moreover, they could improve its design by seeing where things have not been working as expected before they put it on the market.”
