Films measure pressure distribution and magnitude from 2-43,000 PSI
(0.14-3,000 kg/cm2) between heat-sealing platens and rollers. When
placed between contacting surfaces, Prescale® instantaneously and
permanently changes color proportional to the actual pressure applied.
No instrumentation is required but imaging is available for even greater
detail. Used to verify and calibrate contact pressures during equipment set-up
and preventive maintenance. By assessing these pressures, packaging
integrity can be ensured. Film conforms to straight and curved surfaces,
and can be hand or laser cut to any size and shape.
