Application and use

The specially developed surface of HERMAlaser sheet offers optimal printability and toner keying with all xerographic printing processes. Label sheets are suitable for large laser printers, desktop laser printers, copiers and a great number of inkjet printers.

We recommend production from narrow reels width 217 mm or width 434 mm for double-width production (original edges of the semi-finished rolls should not be adopted for sheetstock). A possible curl in machine direction (especially towards the cores) may be adjusted by a "decurl bar" in the press. Water based inks may have an adverse influence on the flatness of the sheet stock. We therefore advise against use of water based inks especially when printing large areas. Furthermore the paper is certified with the EU-Ecolabel (EU-Flower).

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

Adhesive 62A is a universally applicable permanent adhesive with excellent adhesion properties on various surfaces. It features very high adhesion on both polar and nonpolar (PE) surfaces. The adhesive is suitable for autoclave sterilisation, preferably in combination with vellum paper. The adhesive is highly water proof and particularly resistant to light, heat and ageing.

This coated kraft liner has been designed for production of label sheets for copiers and laser printers. The reverse of the paper assures excellent processing characteristics, i.e. high friction combined with high abrasion resistance.

Processing

Excellent die-cutting characteristics on all customary machines. HERMA KW (512) was designed for sheeting. It is less suitable for conversions where waste-stripping is involved.

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 four years from date of production.

Regulations concerning contact with food

The paper is approved according to the Recommendation XXXVI. This paper grade according to the sample material submitted may be used safely for food packaging. It may stand in direct contact with dry and fatty foodstuffs. (ISEGA Research and Development Institute, Aschaffenburg)

All ingredients of adhesive 62A comply with recommendation FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 62A 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 29.11.2025).

Furthermore the self-adhesive labels with the adhesive 62A can be used for labelling of blood bags (Expert's Opinion from November 11, 2021).

The paper complies with recommendation BfR XXXVI.
