Application and use

The surface of HERMAinkprint matt with its special coat is particularly suitable for inkjet printers (piezo, bubble-jet and memjet technologies). Thanks to its specially designed surface characteristics an outstanding quality of the imprint is achieved on all usual inkjet printers (resolution with photorealistic print up to 1440 dpi).

Adhesive 63S was specially developed to have extremely high tack on various substrates. Because of the high final adhesion 63S is very suitable for long-term identification, for labelling of difficult substrates and non-polar surfaces. This new kind of an adhesive gives on various substrates like PE, PET, aluminium, steel etc. similarly extreme high final adhesion values. Therefore it is suitable with the right face material or security die cutting as a tamper-evident-solution or as a seal for originality. Depending on the substrate the final adhesion will be reached in some cases in 24 hours. The tamper-evident-function is thus influenced by the surface (in folded boxes from the applied varnish) and by design of the substrate, by the design of the label and by the conditions in the end use. 63S has a particularly good resistant against light, heat and aging. The supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

Processing

Because of the high tack and increased coat weight the matrix stripping is recommended to do immediately at/after die cutting. As part of a self-adhesive compound HERMA PW (525) 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 paper grade HERMAinkprint matt (137) according to the sample material is physiologically and toxicologically safe and may therefore be used in printers and scales for the marking of goods. However, they m ay only stand in direct contact with those foodstuffs which are washed or peeled before consumption (ISEGA Research and Development Institute, Aschaffenburg).

The pressure-sensitive adhesive 63S 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 and moist non-fatty foodstuffs (Declaration of no objection valid until 12.07.2025).

Furthermore the self-adhesive labels with the adhesive 63S can be used for labelling of blood bags (Expert's Opinion from July 12, 2021).

The paper complies with recommendation BfR XXXVI.
