Application and use

The specially developed surface of HERMAlaser sheet 50 offers an excellent printability and toner keying with all xerographic printing processes. Label sheets are suitable for large laser printers, desktop l aser printers, copiers and a great number of inkjet printers.

We recommend a production from small reels 217 mm wide or 434 mm wide for two-wide production (original edges of the semi-finished material should not be used). A possible curvature in machine direction (especially near the cores) may be adjusted by a "decurl bar" in the press. Water-based inks may negatively influence stay flat characteristics of the paper. We therefore recommend no use of water-based inks for printing large areas.

The pulp for this paper is from FSC® certified forests and other controlled sources.

Adhesive 62Z has a very wide spectrum of applications. It is suitable for rough and curved surfaces as well as for synthetic surfaces and packaging films. The adhesive is highly 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. Adhesive 62D is a universally applicable permanent adhesive. It has a wide range of applications including high-quality industrial labels. It is suited for labelling rough but not extremely curved surfaces and is highly resistant to light, heat and ageing. Typical areas of application for this coated kraft liner are computer labels for laser printers (continuous or sheet stock), which require higher stiffness.

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. Excellent die-cutting characteristics on all customary machines. As part of a self-adhesive compound HERMA KW (527) offers good die-cutting characteristics with all customary flatbed and rotary label cutters.

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

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

The pressure-sensitive adhesive 62Z 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 5 in accordance with Regulation (EU) No. 10/2011. Furthermore, the adhesive may be used for laminating plastic films. 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 21.04.2025).

Furthermore the self-adhesive labels with the adhesive 62Z can be used for labelling of blood bags (Expert's Opinion from April 29, 2021).

The paper complies with recommendation BfR XXXVI.

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

The pressure-sensitive adhesive 62D 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 4 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 21.04.2025).

Furthermore the self-adhesive labels with the adhesive 62D can be used for labelling of blood bags (Expert's Opinion from April 15, 2021).

The paper complies with recommendation BfR XXXVI.
