Adhesive 52W

Application and use

The adhesive 52W is developed for recycling applications where the label has to be removed in warm alkaline water. By the specific removal of the label from the substrate, the bottles can be recycled cleanly. The adhesive 52W is just recommended for PET substrates like PET bottles or PET packaging. On polyolefin substrates like PE or PP the adhesion can be too low.

Finishing: The soft adhesive requires special care during further processing.
Printing machines in which the adhesive material is exposed to very high temperatures above 70 ° C for a long time are not recommended for further processing. Printing on conventional printing machines (such as UV Flexo) does not pose any problems in further processing

Recyclability: Good results are reached with 65 °C in 1 % alkaline water. 52W was specially designed for PET bottles e.g. for beverages, detergents, cosmetics, personal care which can be recycled in industry-standard recycling facilities. A main characteristic of the product is that the adhesive is separated from substrate and label material and therefore the plastic flakes do not get sticky after drying in the recycling process. This enables a clean separation by sink-float separation and air elutriation.

The specific application conditions should be verified by pre-tests.
