Peel strength testing is an essential method used to evaluate the strength of adhesive bonds between two substrates. The test measures the force required to separate a bonded surface at a controlled speed and angle. Industries that rely on adhesives, tapes, laminated surfaces, or packaging materials regularly use this test to ensure the integrity and reliability of their products.

Pacorr’s Peel Strength Tester enables manufacturers to precisely test adhesive bonds under two different conditions, allowing for comprehensive analysis of the material's performance.

Types of Peel Tests: 90-Degree and 180-Degree Tests
Pacorr's Peel Strength Tester supports both the 90-degree peel test and the 180-degree peel test, two of the most widely recognized methods in the industry. Each test focuses on evaluating the bond strength from a different angle, and their applications vary based on material properties and usage.

1. 90-Degree Peel Test
The 90-degree peel test involves peeling the substrate from the base material at a right angle (90 degrees). This test is ideal for measuring the adhesive strength of flexible materials bonded to rigid surfaces, such as labels on containers, laminates on rigid packaging, or tapes.

How It Works:

• A sample is clamped to a fixture where one end is adhered to a flat, rigid surface.
• The testing instrument applies a controlled pulling force to peel the sample at a 90-degree angle.
• The force required to peel the material is recorded, and the average peel strength is calculated.

Benefits of the 90-Degree Peel Test:

• Accuracy: The 90-degree peel test provides highly accurate results for evaluating the adhesive properties of flexible materials on rigid bases.
• Real-World Simulation: This test mimics real-life applications, making it particularly useful for packaging, automotive, and electronics industries.
• Preventing Delamination: By identifying weak adhesive points, manufacturers can prevent product failures due to delamination.

2. 180-Degree Peel Test
The 180-degree peel test is a more straightforward test where the substrate is peeled from the base at a flat, parallel angle (180 degrees). It is ideal for testing adhesives between two flexible materials, such as tapes, films, or textiles.

How It Works:

• The sample is secured at both ends, with one end fixed to a moving clamp.
• The moving clamp pulls the sample apart at a 180-degree angle, separating the bonded materials.
• The force required to separate the two materials is measured and recorded.

Benefits of the 180-Degree Peel Test:

• Versatility: This test can be applied to a variety of materials, including textiles, tapes, and flexible films.
• Consistency: It offers consistent, repeatable results, providing reliable data on the bond strength between two flexible materials.
• Material Optimization: Manufacturers can use the results to optimize adhesive formulations and improve product performance.
