The following requirements generally apply to pharmaceutical packagings:
Another major challenge for testing technology in the pharmaceutical industry is the high cycle or production rates. LIWO offers complete leak/flow/function test modules for production rates up to 220 parts per minute.
The helium leakage test is suitable for small leaks. For testing, the packaging must be filled with helium. It must be ensured that helium is still present in the pharmaceutical pack at the time of measurement. This is very complex and partly not permissible.
