Stamping and thermal transfers can be used for glossy or textured surfaces of injected, extruded and thermoplastic products. These decorative methods have been proven successfully on Eastman’s Spectra® and Eastalloy® polymers.

Stamping

Stamping is the use of hot tool engraved with text or design patterns, by which the color of metallic foil can be transferred onto the product surface under a certain pressure, thereby obtaining fine patterns or text. Stamping is popular because it can be used for many different colors, with good persistence and beautiful products, not to mention that this method is both simple and economic.

Thermal Transfer

This method uses a special thermally conductive silicone rubber to print a heat-transferred label or logo onto the product. The print effect of thermal transfer can be very colorful.

Abrasive and Chemical Resistance

If a protective layer is added to the stamping foils or thermal transferred labels, it will improve the abrasive resistance and chemical resistance of the printed surface. Using high pressure to create recessed foils and labels below the product surface can also improve abrasive resistance.

Hot Pressing Conditions

Hot pressing conditions should follow material supplier’s recommendations or be verified through testing. As for copolyesters, we recommend a nozzle temperature of 149℃-204℃, a residence time of 1-2 seconds and a pressure of 0.62MPa.
