news.Mettler Toledo Safeline has launched a new seal-inspection tool that runs at speeds of up to 120 meters per minute and can identify particles down to 1 mm caught in the seal areas.

The seal-inspection tool forms part of the PowerChek and PowerChek Plus x-ray inspection systems. These multi-tasking inspection tools are the technological defenders of brand values. They catch several quality-control problems simultaneously. Typical problems include detecting contaminants, monitoring fill levels, and inspecting seals for stray particles.
The seal-inspection tool in the PowerChek and PowerChek Plus incorporates an application specific low energy source and a high-contrast detector. The combination provides more detail and better contrast in an area of packaging – the seal – that is hard to inspect because of its low density. Conventional x-ray systems typically use a higher energy source and detector. The image they generate offers minimal detail in this low-density area of the pack. Seal-inspection equipment based on LED light source is incapable of performing other product checks in parallel, such as contamination detection.
By setting the parameters and fine-tuning the sensitivity, operators can train the X-ray inspection software to catch particle-compromised seals, while keeping false rejection rates close to zero.
