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.
85
Case study
Injection moulded assembly integrity
Customised engineering example
Plastic injection-moulded subassemblies are often clipped or welded together, and the integrity of the whole must be tested at several points.
