Question 1

Product Description

Accepted Answer

3M Thermoscript films have been developed for subsequent marking using the thermal transfer printing process. Their smooth material surface enables a flat, opaque color transfer for precise markings, e.g. with high-density barcodes. We recommend the use of thermal transfer ribbons based on synthetic resin.  
Other printing methods such as screen printing, flexographic or letterpress printing are possible. Due to the different color qualities offered on the market, a color suitability test by the user is recommended before production. Equipped with a glassine protective paper, the Thermoscript films are suitable for the automatic dispensing of film labels.  
The foils are suitable for bonding to metal, paints and high-energy plastics. For bonding to low-energy substrates, we recommend 3M Thermoscript foils with the 300E / 350E adhesive series. Please contact our product specialists for further information.
