Q: Functionality and durability

Based on our current findings, the following performance and durability can be expected from 3M Thermoscript foils. Typically, these durations are not less than the following times for vertical outdoor weathering, provided the foils have been professionally processed and applied according to 3M recommendations: Durability Outdoor use: 2-3 years Indoor use: almost unlimited Shelf life 2 years Recommended Storage Conditions 23°C / 50% relative humidity. Storage of film/label rolls in polybags is recommended.

Question 1

Product Description

Accepted Answer

3M Thermoscript films were developed for subsequent labeling using the thermal transfer printing process. Their smooth material surface enables a uniform, opaque color transfer for precise labeling, e.g., with high-density barcodes. We recommend the use of resin-based thermal transfer ribbons.  
Other printing methods such as screen printing, flexographic, or letterpress printing are possible. Due to varying ink qualities offered in the market, a color suitability test by the user before production is recommended. Equipped with glassine release liner, Thermoscript films are suitable for 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 adhesive series 300E / 350E. Please consult our product specialists.
