Application and use

The semi-gloss coated surface of "HERMAsilver matt reverse coated" offers good printability in conventional label printing methods (e.g. UV-flexo) as well as in thermal transfer printing. A verification of ink/ribbon suitability is recommended.

Due to its total opacity the material completely obscures the labelled surface. It is highly conformable and may therefore be used on flat as well as on curved surfaces. The aluminium layer on the back side of the label paper serves as barrier and prevents migration of contaminants from the labelled surface or ingredients of the adhesive into the label material.

Therefore "HERMAsilver matt reverse coated" is suitable for the labelling of tyres.

Thanks to its extremely high adhesion adhesive 64B is particularly suitable for labelling strongly curved, rough, dusty or oily surfaces as well as rubber products and containers for chemicals. In combination with HERMA PE laser this adhesive is suitable for labelling chemical barrels after filling them at a maximum temperature of 180 °C.In spite of its high coating weight this newly designed adhesive offers excellent die-cutting characteristics. Adhesive 64B is 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

Good die-cutting characteristics on all usual machines. As part of a self-adhesive compound HERMA PH (523) 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 paper complies with the recommendation BfR XXXVI, the labels produced with it may be in direct contact with dry, non-fatty food. The silver, laquered side may also be in direct contact with moist and fatty foods.

All ingredients of adhesive 64B comply with recommendation FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 64B 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 5 in accordance with Regulation (EU) No. 10/2011. Furthermore, the adhesive may be used for laminating plastic films. In this case, cut edge contact with food is harmless as far as the above mentioned adhesive is concerned (Declaration of no objection valid until 14.03.2026).

The paper complies with recommendation BfR XXXVI.
