Pharmaceutical blister films with an aluminum look, but with polymer speeds!


kpSilver™ is designed as a high-speed thermoforming option with the look of an aluminum cold-form foil (CFF) package.  In testing, kpSilver™ processed at speeds 84% faster* than comparable CFF lines.  Consider the labor and energy savings you could enjoy, not to mention reducing the overall packaging weight by more than 30%*, by switching from a CFF package, to kpSilver™!

*Results may vary depending on equipment used and blister size.
