Introduction
Peel strength isn’t something that you ignore. Manufacturers conduct various tests on samples, starting with two materials: layers, coatings, films, or adhesive surfaces. Whether flexible packaging or laminated films, improper adhesion can create loopholes. Yes, it leads to delamination, leakage, product failure, or loss of functionality.
To counter these issues, you need to bring the ideal Universal Testing Machine (UTM). The tensile testing machine provides a controlled way to measure the force required to separate bonded materials.
As Testron’s universal tensile testing machine complies with international standards, it produces validated methods, and every method maintains the correct standard.

What Is Peel Testing?
Peel testing measures the adhesive strength between two flexible substrates or a flexible substrate and a rigid surface.
The tensile test apparatus is effective to do the following types of tests:
90-Degree Peel Test
Best suited for flexible substrates bonded to rigid backing plates,
180-Degree Peel Test
Ideal for flexible materials
T-Peel Test
Perfect for unbacked flexible-to-flexible bonded material

How Does Peel Testing Work on a UTM?
A UTM converts the mechanical separation into a measurable force. That’s the simple way of conducting a peel test and measuring force and displacement data.
When you want a typical type of peel test, one part of the specimen is fixed, and the other layer is attached to the opposing grip. The machine moves its crosshead at a certain rate to do the peeling.
The device follows the given working method:
- Prepare the sample and refer to the applicable standard
- Use a proper UTM grip to secure the specimen
- Apply controlled pulling force to begin the test
- Separate the bond layers while using the specified peel angle
- Keep track of force vs. displacement details or peel distance
- Calculate the adhesion or peel strength for the specified test region

What Does Peel Testing Measure?
While doing the peel test, the tensile test equipment is set to measure different values. With the right tensile testing equipment, users can calculate the following:
- Average Peel Force
- Peak Peel Load
- Linear Adhesive Strength
- Failure Mode Identification
- Laminate bond strength
- Interlayer adhesion
- Adhesive consistency
- Rubber-to-substrate adhesion
- Failure behavior during separation
- Batch-to-batch variation
Manufacturers use peel testing with the help of a universal testing machine utm to address their challenges in the following areas:
- Quality Control
- Material Selection
- Process Validation
- Product Development And Troubleshooting.
Major Applications of Peel Testing
1. Plastic Films and Flexible Packaging
Peel testing is very common among packaging and plastic manufacturers and R&D labs. The operations that QC managers use UTMs for in the mentioned applications:
- Adhesive-laminated structures
- Plastic film laminates
- Multilayer packaging films
- Film-to-film adhesion
- Peelable packaging seals
- Flexible barrier materials
- Coating adhesion
For testing of plastic films to sealant layers, the UTM complies with ASTM F88/F88M and F88/F88M-23, ASTM F2824, and ASTM F904.
Therefore, Testron incorporates guidelines related to the above standards as they conduct seamless peel testing while using the appropriate servo hydraulic universal testing machines.
2. Rubber and Elastomer Products
Rubber products are going through adhesion and peel testing to verify their rigidity against certain forces. Therefore, the UTMs have the following applications:
- Rubber-coated fabrics
- Hoses
- Belting
- Rubber sheets
- Tire-related components
- Rubber-to-fabric bonding
- Rubber-to-metal or substrate adhesion
These operations are governed by international standards, such as ASTM D413 and ASTM D413-98(2025). When it comes to rigid rubber substances, ISO 813:2019 specifies a 90° peel method. That’s how a universal material testing machine assesses the entire operation.
3. Adhesive and Pressure-Sensitive Tapes
The checking of adhesion strength is a critical measurement. Therefore, UTMs do the following types of applications:
- Labels
- Electrical adhesive tapes
- Packaging tapes
- Double-sided tapes
- Industrial adhesive tapes
- Transfer tapes
- Medical and specialty adhesive tapes
- Protective films
The standards that Testron’s UTMs comply with are mentioned below:
- ASTM D3330/D3330M
- D3330/D3330M-04(2025)
- ISO 29862:2024
4. Adhesive-Bonded Flexible Materials
It is intended for two flexible materials that use adhesive to stick to each other. The T-peel test is useful for this purpose. The test also complies with ASTM D1876 and ISO 11339:2022.
