Application and use

HERMAtherm D is phenol-free and can be used for applications requiring increased resistance to moistue, solvents or grease, e.g. for weight labels (meat packers, supermarkets) or for price marking labels (excellent presentation of EAN and UPC codes). It can be used for moist and dry applications. For applications on soft PVC films individual tests are recommended because contact with plasticizers might have a negative impact on the thermal imprint.

Direct thermal printing is possible with speeds up to 200 mm/s.

The material can be printed by all conventional roll printing methods. The inks should be suitable for thermal paper (solvent-free), a consultation of the ink supplier is recommended. Complete curing of the ink must be ensured. Due to the thermal sensitive characteristics the web temperature during curing should not exceed 50 °C. In general, it is advisable to carry out pretests under customer-specific conditions to ensure suitability.

The pulp for this paper comes from FSC® certified forest management and other controlled sources.

Adhesive 92C is characterized by excellent adhesion to a great variety of surfaces. Thanks to its aggressive adhesive characteristics the adhesive is perfect for polar, unpolar, slightly rough and curved surfaces. The adhesive is perfectly suited for cold-storage applications with very high tack on cold and humid surfaces, particularly films. This supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

Processing

Good die-cutting characteristics on all usual machines. As part of a self-adhesive compound HERMA PH (515) 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 two years from date of production.

Regulations concerning contact with food

The thermal paper grade HERMAtherm D (Grade 919) is suitable for direct contact with foodstuffs that are typically washed, shelled, and/or peeled before consumption, based on experience.

For all other forms of food contact, a functional barrier should be used to prevent migration. The functional barriers have been tested and verified as effective for all categories of foodstuffs in which the thermal paper is likely to be used (food packaging for diary products, meats and seafood, fruits and vegetables, cereal products, confectionary, processed and prepared foods, fats, infant products). In any case, a direct contact is not foreseen.

All ingredients of adhesive 92C comply with recommendation FDA 21 CFR 175.105 (Adhesives).The paper complies with recommendation BfR XXXVI.
