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 42Rpp offers good tack combined with excellent removability from most surfaces, even after long-term labelling. Thanks to its well-balanced adhesive characteristics this removable adhesive is pe rfectly suited for a wide variety of applications. However, the low adhesion of 42Rpp is likely to be insufficient for applications on curved surfaces.The adhesive is 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 (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 one year from date of production.
