Peel Strength Testing
Definition
Peel strength testing measures the force required to peel apart two bonded materials, typically adhesives, from a substrate or between two layers of material. This test is crucial for evaluating the adhesive bond’s durability and ensuring that materials maintain their integrity under stress, such as during handling, transport, or use. Peel strength is often measured using a standardized method, such as ASTM D3330, where a sample of the bonded material is peeled at a specific angle and speed to determine the force needed.
Relevance to the MedTech Industry
Peel strength testing ensures that adhesive bonds, such as those used in packaging, medical devices, or sensors, can withstand the mechanical forces they encounter during product use. It verifies the reliability and safety of the materials, preventing failures that could compromise the product’s function or patient safety.

Adhesive Bonding: The process of joining materials together using an adhesive. Peel strength is a key measure of the bond’s effectiveness.
Tensile Strength: The maximum stress a material can withstand without breaking, which can be relevant when considering the strength of the bond in peel strength tests.
ASTM Standards: The American Society for Testing and Materials (ASTM) provides standards for testing peel strength, such as ASTM D3330, which outlines methods for adhesive testing.
Adhesive Failure: Occurs when the bond between materials breaks or peels away, which is evaluated during peel strength testing to determine the quality and durability of the adhesive.
