Overview
  • 4titude Thermal Test Film (TTF) can be used in conjunction with a roll fed (e.g. a4S Automatic Roll Heat Sealer) or sheet fed (e.g. 4s3™ Semi-Automatic Sheet Heat Sealer) heat sealer
  • It checks the uniformity and reproducibility of the heat sealing block of the instrument
  • The film can be used to effectively test the temperature of the heating block between 160°C and 200°C
Key Features
  • The Thermal Test Film has a thermosensitive color-forming layer plus a protective layer, both attached to the base material
  • Depending on the temperature applied to the film, a color is produced in varying density and hue, giving a perfect image of heat distribution across the heating block of your heat sealer
  • The color varies according to dwell time and temperature
  • The shorter the duration, the paler and more blueish the color
  • The longer the duration, the more saturated and reddish the color
