“Rethink and look for sustainable alternatives.”
HERMA Wash-off adhesives are characterized by their reliable adhesive force, even in cool and humid environments, and can still be washed off residue-free in industrial cleaning processes. HERMA offers washable pressure-sensitive adhesives for a wide variety of applications and washing conditions. HERMA offers solutions for reusable boxes and containers as well as products that are optimally tailored to the recycling of plastic bottles and packaging. In the cleaning process, the HERMA labels are removed from reusable trays or reusable trays in food and plant logistics using water, high pressure and with the help of highly effective cleaning agents. Furthermore, HERMA Wash-off adhesives enable very pure recyclate to be produced when recycling PET bottles or PET, PE and PP packaging, without any annoying residues from paper or film labels or without adhesive residues.
For a greener planet: transporting plants in reusable trays
- Multiple-use systems offer clear benefits in garden plant logistics, where standardised container dimensions predominate
- For defined processes, leading suppliers, including Normpack of the Netherlands, recommend suitable wash-off adhesives – such as HERMA’s 62P
- The adhesive 62P combines excellent wash-off properties, starting at temperatures below 40 °C, with good adhesion that endures even damp cold storage
Many happy returns: how wash-off adhesives facilitate multiple use
- Multiple-use schemes for fresh produce packaging operate better and all the more efficiently when the labels are easy to remove
- Because trays are often exposed to damp and cool environments, however, labels have to stick reliably in these conditions as well
- Global pooling system suppliers, including IFCO and Europool, recommend labels coated with the HERMA adhesive 62P
Supporting the circular economy to optimise the recycling process
Wash-off adhesive 72Hpw and 62Rpw
The wash-off adhesives were developed for recycling applications where the label is to be washed off in warm caustic water. Recyclability: Good wash-off results are achieved from 80°C in 1% caustic soda for adhesives 72Hpw and 62Rpw.
The adhesives have been certified as recyclable by the cyclos-HTP institute. According to the current requirements and evaluation catalogue, the adhesive has no negative effects on the recycling path of transparent PET bottles. This applies in combination with the following labelling materials:
Wash-off adhesive 52W
The adhesive is characterised by the fact that both substrates and label material are separated from the adhesive and do not become tacky again even after drying.
Returpack recommends using the 52W adhesive for the Scandinavian deposit system in combination with the following materials:
As good as new: a second (and third) lease of life for blister packs
- What you see is what you get, which is why clamshell and blister packs are becoming so popular for fresh produce, convenience food and consumer goods
- The PET material is too precious to be incinerated after use; appropriate recycling methods have been available for some time
- The PET flakes and labels have to be cleanly separated for this purpose – it’s easy with the wash-off adhesives 62Rpw, 62P and 52W
Wash and go: getting more out of the most commonly used plastic
- With a 30% market share, PE is not only the most widely used plastic worldwide, but also especially suitable for recycling – retaining the original functionality
- To allow used shampoo bottles to become new ones, however, it is essential that all the integrated materials are separated
- Film labels can be washed off residue-free with the wash-off adhesive 62Rpw and 52W.
