Blister, Sachet & Low Headspace Package Leak Detection 

The VeriPac 410 inspection system offers non-destructive seal and leak detection for blister packs, sachets, and pouches with low headspace.

Multi-cavity blister packs and low head space packaging use a variety of test methods to determine package integrity, with most being destructive, subjective, and unreliable.

The VeriPac 410 utilizes a combination of vacuum decay technology and differential force measurement to identify defective packages. Multiple packages can be tested in a single test cycle, and the 410 identifies which package or cavity is defective. Test results are quantitative and provide operators with a definitive pass/fail, eliminating the subjective and destructive nature of current test methods.

Package quality assurance is achieved by deploying accurate, reliable non-destructive inspection methods, removing subjectivity from the testing process while reducing waste. The VeriPac 410 allows tested product to be returned to the production line and eliminates the significant costs and waste associated with destructive leak test methods.
