3M Thermoscript films with adhesive series 350E solve a variety of labeling tasks. They are primarily characterized by excellent adhesion to powder-coated surfaces and slightly oily substrates. They are even UL-approved in conjunction with most powder coatings. Furthermore, they are suitable for bonding to low-energy substrates such as PE/PP. The variants with a thicker adhesive layer have proven effective on structured substrates.
The 3M Thermoscript films can be post-labeled using thermal transfer printing. The glassine release liner is particularly suitable for automatic dispensing processes.

Based on our current knowledge, the following functionality and durability can be expected from 3M™ Thermoscript films.
Generally not less than the following times for vertical outdoor weathering, if the foils have been properly processed and bonded 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. It is recommended to store the film/label rolls in polybags. |
| Printing | Screen/letterpress/flexographic/offset printing processes A color qualification test is recommended before series production. Note: It is recommended to test the base print for chemical resistance if necessary! |
| Thermal Transfer Printing | The special surface coating of 3M Thermoscript films Series 350E is very well suited for post-labeling using the thermal transfer printing process. The optical appearance and durability of the post-labeling depend on the ribbon used. To achieve an optimal print image, print speed and the transfer temperature of the printhead may need to be varied. |
| Die-cutting | Sharp blades as well as minimal web tension and the use of double-sided siliconized release liner are recommended, to avoid the effects of possible adhesive bleed. |
