The PakScan identifies leaks in single or multiple non-porous sachets, pouches or other flexible packs. The new system is a fully validatable alternative to the Methylene ‘Blue Dye’ Test. As the PakScan leak test is clean, dry and non-destructive, samples which ‘pass’ the test can be re-introduced to the packaging line, reducing sample wastage whilst increasing product yield. When packs are tested using the ‘Blue Dye’ method, packs and their contents cannot be re-used whether they pass the test or not. A Pass/Fail status for each pack is determined by pre-programmed individual test methods, so operators have no influence over the test results. In-process controls allow the operator to monitor validity during each test cycle. PakScan’s inspects up to 4 large sachets simultaneously, each pack measuring up to 250x80x20mm. This speeds up testing and offers a more representative view of the entire production web. The machine can also be customized for smaller or larger format areas or to accommodate specific sample size requirements. On the touch screen, PakScan indicates the Pass/Fail status for each individual sachet, instantly identifying quality assurance issues with the packaging process. Detailed graphical test data is also given for each pack, enabling diagnosis of any problems, and preventing the production of further faulty packs as early as possible. All test data can be stored or printed for further analysis. PakScan can detect leaks as small as 10 microns. Operation requires no special skills, and all machine functions are accessed via a touch screen display. The 3 minute product changeover is tool-less and requires only one low-cost nest for each different product. PakScan is a freestanding, integrated system with internally generated vacuum. The system can be calibrated to National Standards. User access and data storage is designed to be CFR 21 Part 11 compliant.
