Application and use

HERMAtherm top el (922) is phenol-free and can be used where labels of smudge-proof thermal paper are required, e.g. for weight labels (meat packers, supermarkets) or for price labels or in logistics. Applications in humid surroundings are possible.

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

The material can also be printed by conventional printing methods. 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 characteristic 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.

The adhesive 62Gpt shows a very high tack even on cold surfaces down to -10 °C. Due to the high initial tack even on moist surfaces 62Gpt is particularly suited for labelling polar and nonpolar surfaces such as plastic containers, film wrappings and other packaging materials. The 62Gpt suits especially well for fast running dispensers, in which the initial tack has to be built up extremely quickly as f.ex. when the labels are blown on the substrate.Once labelled the adhesive is highly waterproof.

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

Processing

Excellent die-cutting characteristics on all customary 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 top el (922) according to the sample material submitted is physiologically and toxicologically safe and may therefore be used in printers and scales for the labelling of goods. However, it may only stand in direct contact with such kinds of foodstuffs which are empirically peeled, shelled and/or washed before consumption (ISEGA Research and Development Institute, Aschaffenburg).

All ingredients of adhesive 62Gpt comply with recommendation BfR XIV or FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 62Gpt 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 3 in accordance with Regulation (EU) No. 10/2011. Furthermore, the adhesive may be used for laminating various materials. In this case, cut edge contact with food is harmless as far as the above mentioned adhesive is concerned. It must be ensured that the relevant migration limits are complied with by the laminated packaging (Declaration of no objection valid until 25.09.2027).

The paper complies with recommendation BfR XXXVI.
