Pressure Indicating Sensor Film

Fujifilm Prescale® is a tactile pressure indicating sensor film that is used to assess and correct sealing die pressure at the interface between sealing jaws and rollers and reveal potential weak spots, channels and wrinkles at the actual heat sealing surface. When placed between contacting surfaces, the product instantaneously and permanently changes color proportional to the actual pressure applied. When removed, precise pressure magnitude is determined by comparing the resultant color intensity on the film to a color correlation chart. No instrumentation is required, but imaging is available for even greater detail.
