Saicheng 90 Degree and 180 Degree Peel Test

Product catalog summary

Introduction to Peel Testing
Peel testing is essential for assessing the bond strength between materials, particularly in packaging, food, medical, and electronics industries. It ensures adhesives perform as intended, affecting how easily labels and packaging can be removed or opened.

Types of Peel Tests

90-Degree Peel Test: Suitable for semi-rigid or rigid substrates, this test reflects real-world conditions by concentrating stress at the adhesive interface. It is commonly used for pressure-sensitive labels and tapes on rigid substrates.
180-Degree Peel Test: Ideal for flexible materials, this test simulates consumer interactions with packaging. It provides uniform stress distribution, making it suitable for flexible packaging, composite films, and heat-sealed pouches.

Differences Between 90° and 180° Peel Tests

Peel Angles: The 90-degree test separates materials at a 90-degree angle, while the 180-degree test uses a 180-degree angle.
Test Materials: The 90-degree test is for semi-rigid or rigid materials, whereas the 180-degree test is for flexible materials.
Stress Distribution: The 90-degree test concentrates stress, while the 180-degree test distributes stress uniformly.

Importance of Peel Testing
Peel testing accurately assesses adhesive performance, identifies failure modes, and ensures compliance with industry standards. It is crucial for restructuring materials and guaranteeing product quality.

Saicheng Peel Testing Machines

Saicheng 90 Degree and 180 Degree Peel Test-1

90 Degree and 180 Degree Peel Test In daily life, have you noticed that some product labels peel off easily, while others tear, leave adhesive residue, or simply refuse to come off at all? For flexible packaging, this manifests as some packages opening effortlessly, while others prove difficult to open. Behind these everyday products lies a crucial test: peel testing. Peel testing measures the bond strength between materials, ensuring adhesives perform as intended in real-world applications. The most common testing methods are the 90-degree peel test and the 180-degree peel test. Although they share the same principle, they are suited for different material characteristics. Let’s explore the 90-degree peel test and the 180-degree peel test together. What is Peel Testing? Peel testing is a method that applies force at specific angles and speeds between materials, simulating stresses encountered in real-world

environments. It measures the adhesive strength of films, labels, pressure-sensitive adhesives, and tapes, finding widespread use in packaging, food, medical, and electronics industries. 90-Degree Peel Test The 90-degree peel test is more suitable for semi-rigid or rigid substrates. Since these materials cannot bend, this test better reflects real-world conditions. This test concentrates stress at the adhesive interface, enabling precise detection of localized defects. It is commonly used to evaluate the adhesion performance of pressure-sensitive labels and tapes on rigid substrates. 180-Degree...

rigid substrates at a 90-degree angle, while the 180-degree peel test separates flexible materials at a 180-degree angle. 2. Different Test Materials The 90° peel test is more suitable for semi-rigid or rigid materials, while the 180° peel test is more suitable for flexible materials. 3. Different Stress Distribution The 90° peel test mainly concentrates on stress distribution, whereas the 180° peel test has a more uniform stress distribution. Why the Peel Test Matters? Conducting the appropriate peel test accurately assesses a material’s adhesive performance under varying conditions, identifies...
