Application and use

HERMAcoat WS (229) is perfect for high-quality labels with multi-colour imprint. The semi-gloss coated surface offers an excellent quality of the imprint with all conventional printing methods and good printing quality with thermal transfer and laser printing.

Furthermore HERMAcoat WS is printable with digital printing methods. Pre-testing is recommended.

Thanks to its medium wet-strength HERMAcoat WS is well suited for wash-off applications.

 

The adhesive 62Rpw is developed for applications where the label has to be removed in warm alkaline water. Good results are reached with 70 °C in 1 % alkaline water. 62Rpw is specially designed for PET bottles e.g. for beverages, detergents, cosmetics, personal care which can be recycled in industry-standard recycling facilities. When the bottle is introduced into the recycling process, the substrate is separated from the label and can be recycled cleanly.

The supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

The material is certified by the institute cyclos-HTP to have no negative effects on the recycling path for transparent PET bottles according to the requirements and assessment catalogue*.

Regulations concerning contact with food

The paper complies with BfR XXXVI recommendations for direct contact with dry and fatty food.

The pressure-sensitive adhesive 62Rpw can be safely used for the reverse coating of labels for the labelling of food or food packaging materials, respectively, especially for wash-off labels on PET- or glass-bottles.  It may be used in small-area, direct contact with dry and moist, non-fatty food, as far as the ratio of the contact surface of the adhesive label related to the total weight of the food does not exceed 0,1 dm²/kg.
