THERMOSCALE is a heat-sensitive film that changes color according to temperature and contact time, providing a visual map of heat distribution across contact surfaces.

When the film contacts a heated surface, its special layer reacts to temperature, creating a darker color in hotter areas and lighter color where it’s cooler. This lets users instantly see uneven heating or thermal loss.

It’s widely used to check heat-seal uniformity, lamination balance, thermal press temperature, and tooling or die heating consistency in packaging, electronics, and composite manufacturing.

Depending on the grade, THERMOSCALE measures from roughly 80 °C to 210 °C (176 °F to 410 °F), covering typical sealing, lamination, and molding processes.

No. It is a single-use film—once exposed to heat, the color change is permanent and serves as a record of the temperature distribution.

Only light contact pressure is needed for proper color transfer. Excessive pressure can blur or darken the image, so even, gentle contact works best.
