Application and use

HERMA LAM is a specially developed label material for marking with a CO2-laser (colour change from white to black).

HERMA LAM with its protective coating is used wherever labels of smudge-proof, solvent and grease resistant paper are required, e.g. for package labelling or for price marking.

Applications on surfaces containing plasticizers are only partially possible, intensive contact with plasticizers, however, might cause fading of the printed image. Please make individual tests for applications on soft PVC films. Recommended for moist and dry applications.

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.

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 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 two years from date of production.

Regulations concerning contact with food

The paper grade HERMA LAM (92) according to the sample material submitted is physiologically and toxicologically safe if used according to its intended purpose. It may hence be used safely in printers and scales for the marking of goods. However, it may only stand in direct contact with those foodstuffs which are washed, shelled and/or peeled before consumption according to experience (ISEGA Research and Development Institute, Aschaffenburg).

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.
