Application and use
HERMAtherm PP film combines the characteristics of thermal papers with the durability of PP-films.
Printing speeds of up to 200 mm/s are possible in direct thermal printing.
Printing with traditional printing methods like UV flexo or UV offset is also possible. However ink keying of the preprint in wet condition is limited. The inks should be suitable for printing thermal films, consulting of ink supplier is recommended. A corona treatment prior to printing may have a positive effect on ink trapping and ink adhesion.
Web temperature during curing should not exceed 50 °C in order to prevent an early reaction of the thermo reactive ink.
Basically, suitability tests should be performed under customer and application specific conditions.
The thermal print of HERMAtherm PP white 65 features a high water resistance and a limited oil resistance. HERMAtherm PP white 65 does not contain BPA and is suitable for applications where high durability is required such as logistic labels, luggage tags but also for food or meat labels.
