Sealing gauge

摘要

Sensor Products Inc. released Fujifilm Prescale, 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. Sensor Products' films measure pressure distribution and magnitude from 2 to 43,000 PSI between heat sealing platens and rollers. When placed between contacting surfaces, Prescale instantaneously and permanently changes color proportional to the actual pressure applied, the company says. When removed, precise pressure magnitude is determined by comparing the resultant color intensity on the film to a color correlation chart.
