Application and use

HERMA PP flex white (840) 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 white 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 white PE films with a significantly higher thickness are normally used.

HERMA PP flex white is suitable for labelling a wide range of products, from cosmetics, household and cleaning products to beverage and food packaging.

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

The adhesive has been specifically developed for label applications where residue-free removal of the label material in the PET and HDPE recycling stream is required. In addition, the transparent adhesive is also suitable for applications on PP or PS surfaces, providing good resistance to aging, heat, and light.

72Hpw is also suitable for application on glass and has been successfully tested for its removability during the glass recycling process in accordance with the CETIE test method. The final assessment of the recyclability of the labelled bottle remains the responsibility of the respective end user or distributor placing the product on the market.

HERMA PET has excellent properties in demanding applications. The high strength characteristics eliminate web breaks in high speed applications with narrow webs allowing high dispensing speeds. Compared to paper liners HERMA PET is not sensitive to moisture resulting less curl and excellent dispensing properties.

PET Recycling:The label material can be separated without residues in the PET recycling stream. It is certified by cyclos-HTP to have no negative effects on the recycling of PET bottles or trays  (80 °C). The material is fully compatible with PET bottle recycling according to RecyClass (80-85 °C).

HDPE Recycling:The material can be completely separated in the HDPE stream by cold washing (40 °C). It is fully compatible with rigid HDPE recycling stream according to RecyClass and cyclos-HTP .

Glass Recycling:

The label material complies with CETIE requirements for removability in glass recycling.

Processing

HERMA PET is recommended for self-adhesive compounds for which increased safety in die-cutting is required.

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 white 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.
