Application and use

HERMA PP flex clear (847) is a new 45 µm PP label film without topcoat with very good printability. After corona pretreatment, the well wettable outer layer of the PP film can be printed  in UV flexographic printing just as well as conventional corona PE label films or topcoated PP films.

Despite the low film thickness, the stiffness and dispensability of HERMA PP flex clear are comparable to standard PP films. This reduces the amount of material usage and thus contributes to sustainability - without compromising on processing speeds and production efficiency. The film has been specially developed for applications where transparent PE films with a significantly higher thickness are normally used.

HERMA PP flex clear is suitable for labelling a wide range of products, from cosmetics, household and cleaning products to beverage and food packaging. Thanks to its high transparency, labels made from it are optically crystal clear and offer a clear advantage over transparent PE films in this respect.

HERMA PP flex clear can be used to produce very attractive, transparent, glossy labels, which are preferably used on polyolefin plastic surfaces for recycling reasons.

The adhesive 72Hpw was developed for applications where the label has to be removed in warm caustic water (80 °C and 1-2% NaOH).72Hpw was specially developed for PET bottles, e.g. for the beverage, detergents, cosmetics and personal care, which can be recycled in standard industrial recycling plants. When the PET bottles are introduced into the recycling process, the label with adhesive is removed from the PET without leaving any residue so that the PET can be recycled cleanly.

The supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

Certification of Recycling CompatibilityThis self adhesive material is certified by the institute cyclos-HTP to have no negative effects on the recycling path for clear PET bottles according to the requirements and assessment catalogue*. 

*Requirements and assessment catalogue of the institute cyclos-HTP for EU-wide certification (state of 25.04.2025) / Scope of validity according to nation states, see Chap. 1

The material fulfills the requirements of the institute cyclos-HTP for EU-wide certification according to the CHI test method CHO-C8-SEPPO. The label material can be separated without residues in the HDPE recycling stream. 

Processing

As part of a self-adhesive compound HERMA PW (520) 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 one year from date of production.

Regulations concerning contact with food

The label film HERMA PP flex clear is in complinace with Commission Regulation (EC) no. 1935/2004 and (EU) no. 10/2011 and subsequent amendments up to Regulation (EC) no. 2024/3190 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.

The pressure-sensitive adhesive 72Hpw 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 2 in accordance with Regulation (EU) No. 10/2011.
