Application and use

HERMA PE laser has been specially designed for laser printers. Printing tests showed excellent results both with monochrome and colour laser printing. In order to avoid soiling of printers due to adhesive bleed, we recommend use of protected edges only, i.e. original edges of the semi-finished rolls should not be adopted for sheet-stock. A possible curvature in machine direction (especially towards the cores) may be adjusted by a "decurl bar" in the press. Due to the large number of printers on the market, we recommend carrying out processing tests in advance. In combination with suitable inks the matt surface of HERMA PE laser offers an excellent printing quality in all conventional printing methods. Best results in flexographic printing may be achieved with water or solvent based inks. Label sheets produced from HERMA PE laser are particularly suitable for tracking and logistics labels as well as for product marking (e.g. for labelling pallets, containers or barrels).

Thanks to its aggressive adhesive characteristics adhesive 63B is particularly suitable for critical surfaces such as cardboard and ampoules. The adhesive is highly water-resistant and is suitable for labelling cold and humid surfaces. It is extremely 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. As part of a self-adhesive compound HERMA KW (510) 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

All ingredients of adhesive 63B comply with recommendation FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 63B 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 29.11.2025).

Furthermore the self-adhesive labels with the adhesive 63B can be used for labelling of blood bags (Expert's Opinion from Nomvember 11, 2021).

The paper complies with recommendation BfR XXXVI.
