PTI-Europe is an independent closure-testing
laboratory. Performing closure evaluations for plastic closures. Besides resin,
flakes, preform and bottle testing, PTI-Europe also offers closure 
evaluations
for plastic flat top closures. Tests are performed according to the ISBT or
customer specific test methods with state-of-the-art equipment. Various closure
sizes and types can be analyzed for carbonated and non-carbonated beverages.
