What Our Customers Say
Real feedback from packaging professionals worldwide
We run a high-mix schedule for cosmetics and toy boxes; this machine handles every window type we throw at it — thin films, reinforced patches, and tight registration jobs. The integrated registration capability guarantees die-cut alignment, which has significantly reduced rework and kept our line speed up. Robust build and great support made the integration seamless.
The Model Q has completely changed our approach to quality control. We’ve reduced our scrap rate by over 90% and our technicians can now focus on more complex tasks. It paid for itself in just 10 months!
My team loves how safe and easy it is to use. The window patching accuracy has eliminated our waste problems. We’re saving thousands annually on materials alone. Best investment we’ve made in years.
