Application and use

HERMAtherm PP essential (827) combines the characteristics of thermal papers with the durability of PP films.

Printing speeds of up to 150 mm/s are possible in direct thermal printing.

Printing with traditional printing methods like UV flexo is also possible. However ink keying of the preprint in wet condition may be limited. The inks should be suitable for printing thermal films, consulting of ink supplier is recommended.

Web temperature during curing should not exceed 50 °C in order to prevent an early reaction of the thermo reactive layer.

It is generally recommended to carry out tests in advance under customer- and application-specific conditions.

The thermal print of HERMAtherm PP essential (827) features a high water resistance and a limited oil resistance. HERMAtherm PP essential (827) does not contain BPA, BPB  and BPS. It is suitable for applications where high durability is required such as logistic labels, luggage tags or the labelling of food packaging. 

The adhesive has been specifically developed for label applications where residue-free removal of the label material in the PET and HDPE recycling stream is required. In addition, the transparent adhesive is also suitable for applications on glass and PP surfaces, providing good resistance to aging, heat, and light.

The supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

Processing

As part of a self-adhesive compound HERMA PW (520) offers excellent die-cutting characteristics with all customary flatbed and rotary die-cutting tools.

Storage conditions

Storing at a temperature of 20 ± 5 °C, a relative humidity of 45 ± 5 % and a dark storage is recommended. Moisture, heat and direct sunlight have to be avoided.

The shelf life is one year from date of production.

Regulations concerning contact with food

The pressure-sensitive adhesive 72Hpw can be safely used for the back coating of labels for the labelling of foodstuffs for storage at room temperature and below. It may be used in direct contact with dry, moist and fatty foodstuffs that can be assigned a correction factor of at least 2 in accordance with Regulation (EU) No. 10/2011.
