Application and use

The calendered surface of HERMAwhite 170 offers a good quality of the imprint with all conventional printing methods.

HERMAwhite 170 is particularly suitable for thick and stiff specialty labels such as ring labels. With its relatively high stiffness, this material should not be used on curved surfaces.

Adhesive 62A is a universally applicable permanent adhesive with excellent adhesion properties on various surfaces. It features very high adhesion on both polar and nonpolar (PE) surfaces. The adhesive is suitable for autoclave sterilisation, preferably in combination with vellum paper. The adhesive is highly water proof and particularly resistant to light, heat and ageing.

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

Processing

Excellent die-cutting characteristics on all customary machines. As part of a self-adhesive compound HERMA PW (520) offers excellent die-cutting characteristics with all customary flatbed and rotary die-cutting tools.

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 four years from date of production.

Regulations concerning contact with food

The cardboard complies with the legal requirements of the European Regulation (EC) No 1935/2004 as well as with §§ 30, 31 LFGB and BfR Recommendation XXXVI provided that the material is only used in direct contact with dry, non-fatty foodstuffs.

The verification of suitability for the intended purpose and risk management measures are subject to the one who puts the final product into circulation.

All ingredients of adhesive 62A comply with recommendation FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 62A 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 29.11.2025).

Furthermore the self-adhesive labels with the adhesive 62A can be used for labelling of blood bags (Expert's Opinion from November 11, 2021).

The paper complies with recommendation BfR XXXVI.
