How is the 90-degree peel test performed?
A standard 90-degree peel test involves four main steps:
32
Case study
Cosmetics tin label peel
Customised engineering example
Testing the adhesive peel strength of packaging labels applied at the post-production stage is more representative of their performance than at the label production stage.
33
Case study
Adjustable spectacles
Requirement
Adlens manufacture adaptive lenses used within spectacles that are distributed throughout the world. The lenses change power at the turn of the dial located at the side of the spectacle.

Case study
Peel test of semi-rigid packaging for medical device
Customised engineering example
Our client needed to test the peeling quality of a Tyvek® paper lid used to seal a sterile, semi-rigid thermoformed plastic tray containing pre-filled syringes.
35
Case study
Peel testing vacuum-formed containers
Customised engineering example
Semi-rigid thermoformed packaging, sealed by film or foil, is commonly tested by the '45-degree peel method'. This best represents how a person would open the package.
