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).

Adhesive 64Z covers a very wide range of applications. Thanks to its aggressive adhesion properties it is suited for an extensive variety of even critical surfaces such as rough cardboard and slightly dirty surfaces. The adhesive is highly resistant to heat, light 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.

The material complies with BS 5609 Section Two (Resistanceto Sea Water).
