New Semi-Automatic Leak Tester For Blister Packs Introduced By Bonfiglioli

Until recently the Methylene Blue Dye leak testing method has been used for blister packed tablets. This process, being messy, destructive as well as dependent on human errors, has now been finally replaced by a clean, precise, non-destructive leak tester that can be easily validated to detect, from cracks down to micro-leaks.

The compact LF-BLI machine is ideal for sample testing between the existing Blister Line and Cartoner Packing line. The blister packs are manually inserted on a test base, which may take up a number of blister packs depending on the size. A sensitive membrane is then sealed on the test base and a vacuum is applied, which (when set under a predetermined vacuum) will analyze the swelling of each blister cavity, thus indicating which blister pack is faulty. The machine will also indicate which cavity is leaking.

The main advantage of this machine is that no extra tooling is required for different size blister packs as the Sensitive membrane will adjust to any size and shape. The LF-BLI machine is fully computerized utilizing a SCADA platform. The software is easy to operate and includes utilities such as a products database, statistical reports etc. A printer may also be installed for printing test results and parameters. The technology is highly precise and fully validated.

The LF-BLI will be on display at Interpack 2008 in Dusseldorf, Germany at the Bonfiglioli Engineering booth Hall 6 Stand 6C57.
