Application and use

The semi-gloss coated surface of HERMAcoat opaque offers an excellent print quality in all conventional printing methods as well as in thermal transfer printing. Due to its total opacity the label material obscures the labelled surface completely.

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

The adhesive 62Gpt shows a very high tack even on cold surfaces down to -10 °C. Due to the high initial tack even on moist surfaces 62Gpt is particularly suited for labelling polar and nonpolar surfaces such as plastic containers, film wrappings and other packaging materials. The 62Gpt suits especially well for fast running dispensers, in which the initial tack has to be built up extremely quickly as f.ex. when the labels are blown on the substrate.Once labelled the adhesive is highly waterproof.

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 two years from date of production.

Regulations concerning contact with food

All ingredients of adhesive 62Gpt comply with recommendation BfR XIV or FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 62Gpt 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 3 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 10.10.2025).

The paper complies with recommendation BfR XXXVI.
