Application and use

HERMAsilphie (341) is made from approx. 35 % silphie fibre and 65 % recycled fibre. With its special look and feel, the material creates an authentic natural impression.

The silphie fibres, which replace the short-fibre pulp in the paper, come from the regionally grown, annual Danube silphie plant, which is primarily cultivated as an energy crop. The dual use of the silphia plant as a raw material for paper production and as an energy crop in biogas plants makes the paper an exceptionally sustainable product.

HERMAsilphie (341) can be printed very well using offset and flexographic printing as well as digital printing processes. The coulour of this ecological, sustainable product denpends on the raw material used and can therefore vary from batch to batch.  Due to the inherent colouration of the paper, the use of opaque white is recommended for light colours. Preliminary tests are recommended.

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.

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 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.
