Application and use

Thanks to its special surface treatment the glossy surface of HERMA PP 50 transparent tc offers an excellent printing quality in all conventional printing methods like e.g. UV flexographic printing. The primer on the back ensures perfect anchorage of the adhesive. In combination with the appropriate adhesive, this product is perfect for applications where the removability of the label is required. This film is not intended for use in unprinted zigzag applications, in which the coated print surface is in contact with itself.

HERMA PP 50 transparent tc is perfect for the production of optically demanding, glossy transparent labels. It is particularly suitable for labelling cosmetic products, cleaning agents etc., as well as for applications demanding resistance to chemicals or weather.

The adhesive 63F was developed specially for applications where high transparency with low tendency to creep is needed. The combination of a high tack and a high cohesion, which reduces the adhesive bleed, together with a very good final adhesion characterises the 63F. Furthermore the UV-stability is extremely high and wetting on polar surfaces like glass and steel very good. In addition 63F features an extremely good resistance against whitening.The 63F has an excellent resistance to aging, heat, water and light.

Typical uses for this biaxially stretched polyester film are high-speed labelling machines with optical or mechanical scanning.

Processing

Excellent die-cutting characteristics on all customary machines. In a self-adhesive compound HERMA PET offers excellent die-cutting characteristics with all usual flatbed and rotary die-cutting machines.

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 label film HERMA PP 50 transparent tc complies with the legal requirements or recommendations of Regulation (EC) no. 1935/2004 and (EU) no. 10/2011 and subsequent amendments up to Regulation (EC) no. 2020/1245 on plastics and articles intended to come into contact with food as well as of Regulation (EC) no. 2023/2006 on good manufacturing practice for materials and articles intended to come into contact with food.

All ingredients of adhesive 63F comply with recommendation FDA 21 CFR 175.105 (Adhesives).

The pressure-sensitive adhesive 63F 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. Furthermore the self-adhesive labels with the adhesive 63F can be used for labelling of blood bags (Declaration of no objection valid until 06.04.2025).
