Application and use

The specially developed surface of HERMAlaser sheet plus 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 sheet stock). 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.

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

The pressure-sensitive adhesive 72Bpt is specially developed for applications where the labelled packaging material, paper or board, is recycled after use. It is not necessary to separate the label for this, as the adhesive 72Bpt does not have negative effects on the recycling path for paper packaging materials. The recycled paper or packaging material can be reused and printed on without any problems. In relation to the total packaging material, the weight share of the label can be up to 25%. 

 

The adhesive 72Bpt has a very high initial tack and is therefore also suitable for fast-running dispensing systems in which the initial tack has to be built up extremely quickly (e.g. blow-on process).

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

Die-cutting properties are excellent on all common 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 two 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 the pressure-sensitive adhesive 72Bpt comply with the recommendations BfR XIV or FDA 21 CFR 175.105 (Adhesives).

 

The pressure-sensitive adhesive 72Bpt can be safely used for the back coating of labels for the labelling of foodstuffs for a storage at room temperature and below. It may stand in direct contact with dry, moist and such fatty foodstuffs that can be assigned a correction factor of at least 3 in accordance with the Regulation (EU) No 10/2011 (declaration of no objection valid until 26.10.2025).
