Conduct peel strength test on duct tapes precisely with peel tester

Packaging tapes or pressure-sensitive tapes are widely used materials that will help in ensuring the integrity of products. These tests play a vital role in evaluating the adhesive force needed to separate two bonded surfaces, offering manufacturers valuable insights into the quality and durability of their products.

A comprehensive understanding of peel strength is essential as it directly influences the material's capacity to withstand diverse environmental conditions and meet specific application requirements. With Presto peel bond tester, manufacturers can easily conduct peel strength tests on duct tapes and ensure quality materials will be delivered to the customers. 

In this blog, we will discuss brief information about how you can easily conduct peel strength tests on duct tapes with the help of this quality testing equipment.

Perform accurate peel strength tests on duct tapes with a peel tester

Peel strength stands out as a critical material property, reflecting the force needed to detach a pressure-sensitive or adhesive tape from its substrate. The packaging test involves affixing the sample to the substrate and steadily pulling on the tape's free end. 

Manufacturers can efficiently perform quality tests on materials through precise assessments, including 180-degree and 90-degree peel adhesion tests, ensuring accurate evaluation of the sample. This precise measurement of adhesive strength simplifies the quality testing process for manufacturers.

This method is utilized to assess characteristics, comfort, and quality control. Testing is conducted in accordance with JIS Z0237 (2022) [Self-adhesive tapes - Determination of peel adhesion properties], focusing on the relevant sections. Additionally, alternative peel testing options are offered, such as the 180-degree peel test and the probe tack test, catering to diverse sample types and specific requirements.

All about Presto peel testing machine

Presto's Peel Adhesion/Bond/Seal tester is employed to assess the enduring adhesion capability of self-adhesive force-sensitive products. Adhesion strength, defined as the pressure needed to separate a coated substance from another plate under specified conditions, is measured with a normal test plate at a predetermined angle and velocity. This product is meticulously designed and manufactured in compliance with international standards.

Ideal for evaluating tear, peel, and other frictional properties of various materials like adhesives, laminates, glues, fabrics, packaging, coatings, tapes, labels, etc., the Peel Strength Tester ensures accurate measurement of peel strength load over a specific distance of adhesive. The machine boasts a constant rate of extension and constant rate of load control, enabling multiple peel and seal tests with a single device.

Presto offers two models of the Peel Strength Tester: the Digital Model and the Computerized cum Digital Model.

Equipped with two grips, the tester conducts the test by placing a sample with gum-coated material between the grips under specified conditions. While the upper grip remains fixed, the lower grip moves downward to assess the adhesion strength of the coated substance at a specified speed.

Presto's Adhesion Strength Tester enables the controlled peeling of laminated materials at a 180-degree angle, with a separation rate of 300 mm/minute and a precision of +/- 2%. This peel strength tester finds extensive application in the paper and packaging industry, serving to assess various material properties such as peel strength, bond strength, and more.

This testing machine comes with different fixtures that will help to secure both the tape and substrate to the universal testing machine. 

Different samples can be tested using a Presto peel strength tester

A duct tape is a type of pressure-sensitive tape that will consistently adhere to a surface upon the light pressure. This will help to achieve the delicate balance between adhesive holding capacity.

There are different types of samples that can easily be tested using a Presto peel tester.

Below we have listed them:

• Primer: A primer enhances the adhesive's holding power to the backing. It can be a liquid substance applied to the backing material or a physical treatment like corona or flame treatment. This is crucial for tapes requiring clean removal or subjected to permanent stress.

• Release Coating: The backing of a single-sided tape and the release liner for a double-sided tape undergo treatment with a release coating. This coating ensures stable unwinding of the tape during the application, particularly important for high-speed automatic applications. The release coating can be tailored to have varying release forces for easy or more resistant unwinding, depending on the customer's requirements.

• Adhesive Coatings: Adhesives commonly encompass acrylic, natural rubber, or synthetic rubber. In addition, there are more specialized options with a limited range of applications, such as silicone, butyl, or EVA (ethylene-vinyl-acetate).

Peel strength is commonly employed to gauge the bond strength of a material, often an adhesive. It represents the average load per unit width of the bond line necessary to separate bonded materials, with the separation angle set at 180 degrees. You can easily conduct peel strength test materials easily with the help of this quality testing equipment.

Importance of testing duct tape accurately for peel strength test

The pressure-sensitive tapes can easily provide the material with tacky adhesive on at least one side. It becomes activated under pressure, adhering only when compressed. What sets pressure-sensitive adhesive apart from other adhesives is its ease of application, requiring minimal effort for adherence. Unlike some tapes that may need water, solvent, or heat to activate the adhesive, PSA activates simply through pressure. Furthermore, it remains in a consistent state and does not undergo a change of phases, such as transitioning from a liquid to a solid.

Heat-activated tape typically lacks tackiness until exposed to a heat source. Activation of heat-activated tape involves subjecting it to elevated temperatures, typically at 180˚F or higher, to establish a bond. The adhesive activated by heat enables robust bonding, particularly on challenging surfaces like rubber, EPDM, PU, and PVC-based plastic materials. This type of tape can be manufactured with various carriers, making it versatile for a range of applications.
