Q: Functionality and durability

Based on our current knowledge, the following functionality and durability can be expected from 3M Thermoscript foils. Generally, not less than the following times with vertical outdoor weathering, if 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 Condition: 23°C / 50% relative humidity. Storage of the film/label rolls in polybags is recommended.

Q: Processing

Printing: Screen / Letterpress / Flexo / Offset printing processes A color qualification test before series production is recommended. Note: It is recommended to also test the base print for chemical resistance if necessary! Thermal Transfer Printing: The special surface coating of the 3M Thermoscript films Series 300E is very well suited for subsequent labeling using the thermal transfer printing process. The optical appearance and durability of the subsequent labeling depend on the ribbon used. To achieve an optimal print image, the printing speed and the transfer temperature of the print head may need to be varied. Die-cutting: Rotary die-cutting, sharp blades, and minimal web tension are recommended to prevent possible adhesive squeeze-out. Pretreatment of substrates / bonding: See processing information KG-054

Question 1

Product Description

Accepted Answer

3M Thermoscript foils have been developed for subsequent marking using thermal transfer printing. Due to their homogeneous material surface, a full, opaque color transfer is possible. The foils are also characterized by excellent adhesion to low-energy substrates, such as polyethylene and polypropylene. Equipped with glassine protective papers, 3M Thermoscript foils are recommended for automatic dispensing processes.
