Peel Strength Testing is a method used to measure the bond strength of a material, typically an adhesive. This test determines the average load per unit width required to separate bonded materials at a 180-degree angle. It's a key way to evaluate the performance of adhesive bonds.

Peel Seal Adhesion Strength Tester

The Peel Seal Adhesion Strength Tester is an advanced instrument designed to measure the adhesion strength or peelability of self-adhesive pressure-sensitive materials. Peel adhesion is defined as the force needed to test the strength of adhesives.

How It Works

The instrument features two jaws to hold the sample securely. The specimen is placed between two movable clamps that apply a force to peel it off the surface. This force is measured by a highly accurate load cell and displayed on a digital screen. This setup ensures precise data, helping manufacturers deliver high-quality products.

Popular Tests Conducted

The Peel Strength Tester is widely used in the packaging and adhesive industries to evaluate adhesive strength. The following tests can be performed with this instrument:

1. Adhesive strength test

2. Peel strength test

3. Seal strength test

4. Bond strength test

Compliance and Models

The instrument complies with various standards, including ASTM D429-14 and ASTM D903. Available models include computerised options for peel, adhesion, bond, and seal strength testing.

Working Principle of the Peel/Seal Strength Tester

The tester is designed with advanced features to determine the peelability of bonded materials. It uses two movable jaws that clamp the specimen and move in opposite directions linearly, applying peel strength to the sample. The peak load the specimen can withstand is shown on a digital display, ensuring precise test results. This instrument can perform peel, seal, bond, and adhesion tests.

Applications of the Peel/Seal/Bond Strength Tester

• Textile Industry

• Flexible Packaging Items

• Bond Strength of Tapes

• Adhesive Strength

Advantages of the Peel/Seal Strength Tester

This tester is an essential tool for manufacturers in the flexible paper and packaging industries. It helps determine the peelability of tapes and adhesive materials, ensuring they can withstand required peel strengths. By achieving a certain level of peel strength, manufacturers gain confidence in their packaging products, knowing they provide a protective layer. The ergonomic design of the instrument allows for quick and accurate testing of various materials repeatedly, enhancing quality control processes.
