Blister packagings are widely used packaging solutions, particularly in the pharmaceutical, food, and consumer goods industries. They typically consist of a transparent plastic mold (blister) and a backing film (usually aluminum or plastic) that individually seals and protects the products.
Their use offers numerous advantages: they enable clear product presentation, provide reliable protection against environmental influences such as moisture, oxygen, or germs, and facilitate the portioned removal of individual units.
Leak testing is an essential part of quality control in the manufacture of blister packaging, as leaks can lead to contamination, loss of active ingredients, or product spoilage. This ensures that each package is sealed airtight and moisture-proof.
Test station for leak testing flexible blister packagings
An inline testing system has been developed to integrate leak testing of flexible blister packagings into the production process. This system uses QLOOP® technology developed by POLMAN AIMES and testing technology from CETA. Flexible blister packagings can be tested for leaks using negative pressure in a space-saving, circulating testing system with multiple test heads. The product is placed in a half-shell. The upper shell closes and the closed test head moves on. The CETA leak test devices, specially developed for this application, move with the test heads and perform the leak test using compressed air as test medium. A pressure change caused by leakage is measured. At the end of the test cycle, the test head is cyclically unloaded and reloaded fully automatically. Test pressures between -100 mbar and -800 mbar are generated in the test devices themselves. Depending on the test head and the cycle rate, hole sizes down to 20 µm can be detected. Depending on the design of the system, several hundred parts per minute can be tested. The transfer of the measurement results from the test device to the control system enables traceability.
CETA test devices and calibration standards are delivered as standard and at no extra charge with an accredited and internationally recognised calibration certificate (compliant with DIN EN ISO/IEC 17025). The warranty for test devices is 3 years (optionally extendable to 5 years). This is a great benefit for the customer.
Cooperation between CETA and POLMAN AIMES – Testing technology and special machine building
CETA Testsysteme GmbH and POLMAN AIMES GmbH have been working together very successfully for several years.
CETA Testsysteme GmbH, based in Hilden, Germany, has been a solution provider and quality manufacturer of leak and flow test devices for 100% end-of-line testing for more than 35 years. Compressed air is used as the test medium. Several thousand CETA test devices are in use worldwide for quality assurance in production lines. With a comprehensive range of test devices and suitable accessories, the right testing technology can be found for almost any testing task (www.cetatest.com).
POLMAN AIMES GmbH, with locations in Wismar, Germany, and Jeddah, Saudi Arabia, is a recognised expert in industrial robotics and process automation. The company has more than 30 years of experience in industrial automation and is specialised in the development of customised solutions. The use of innovative and patented QLOOP® technology results in significant process advantages, particularly in automated production lines (www.polmansolution.com).
CETA and POLMAN AIMES will be exhibiting at FACHPACK 2025 in Nuremberg.
For more than 40 years, the FACHPACK trade fair in Nuremberg is the central meeting place for the packaging industry in Europe. Trade visitors gain a comprehensive overview of product packaging, from manufacturing to quality assurance and logistics.
CETA will be exhibiting together with POLMAN AIMES GmbH from 23 to 25 September 2025 at FACHPACK 2025 in Nuremberg (Hall 7, Stand 7-625). The test station for leak testing flexible packagings will be presented here for the first time.
