Adhesive 72F

Application and use

Adhesive 72F was developed specifically for use in a sustainable labelstock. The raw materials required for its production are based on the so-called biomass balance approach, in which biomass from organic waste is used instead of fossil raw materials. The 72F adhesive is characterized by a high tack with very high cohesion and very good final adhesion. Due to this high cohesion, Adhesive 72F shows a low tendency to creep, so that adhesive bleed is largely avoided. Furthermore, the UV stability of 72F is extremely high and the wetting of polar substrates such as glass and steel is very good. 
72F has particularly good resistance to light, heat, water and aging.

Processing

Excellent die-cutting characteristics on all customary machines.

Storage conditions and shelf life

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.

Regulations concerning contact with food

All ingredients of adhesive 72F comply with recommendation FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 72F 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. 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. Moreover, the adhesive may be used for the labelling of blood bags (Declaration of no objection valid until 06.04.2025).
