New Camera Device Meets Demand for Low-Cost Leak Detection in Pharmaceutical Blister-Packs

Global packaging machinery expert Sepha has developed the world’s first tool-less, vision-based leak detection machine for blister-packs. Visionscan has been developed to meet growing demand from pharmaceutical blister pack manufacturers for a low-cost yet accurate and modern leak detection alternative to the blue dye test that can be integrated into their quality control systems. It will be officially launched at Europe’s largest packing and process show, Interpack, in Germany on 12 May.

Visionscan uses high-resolution camera imaging technology to detect defects in individual blister pockets and weak seals in less than 60 seconds. Because it is tool-less, 21 CFR Part 11 compliant and capable of detecting defects down to 15µm, it is ideal for contract and generic manufacturers where speed, accuracy and multiple product change over is required.

Visionscan is a non-contact and non-destructive test method enabling significant cost reductions to be achieved during the manufacturing process. Sepha CEO, John Haran, states: “At a time when pharmaceutical manufacturers need to improve quality and reduce costs, Visionscan is the ideal product integrity solution because it achieves both cost reductions and improved leak detection accuracy. Customers, particularly those in emerging markets, had been asking us for an accurate, flexible, easy to operate non-destructive blister-pack leak detection device. We used our expertise in blister-pack leak detection technology and worked closely with them to develop Visionscan. Its competitive price point, high degree of accuracy and flexibility across multiple pack formats should make it the global benchmark in leak detection for pharmaceutical blister packs.”

Based in the UK, Sepha has been at the forefront of blister-pack technology for over 30 years. Its leak detection machines are already used by many of the world’s top pharmaceutical manufacturers, including GSK, Bayer, Abbott and Boerhringer. In recent years, Sepha has extended its global reach and now services customers across 60 countries across its leak detection, deblistering, and blister packing divisions.

Visionscan will be available for full demonstration at Interpack (hall 16, stand E23), or via Sepha’s global distributor and agent network.

Detecting leaks in blister packaging has traditionally involved a destructive process, but non-destructive methods, which do not result in wasted products, have emerged as viable...
Demonstrating the integrity of pharmaceutical blister packs is critically important, as any defects can affect the shelf life and efficacy of the contents.
This white paper will test the hypothesis that the VisionScan is considered non-destructive.
