Everything you need to know about wash-off labels
Wash-off labels
In the process of sustainability and recycling, brands are continually striving to make their packaging greener. Wash-off labels are a notable and revolutionary trend within the packaging industry. But what are wash-off labels exactly, and how do they improve recycling processes?
What are wash-off labels?
Wash-off labels are designed to be easily removed from packaging. This leads to a more
efficient and better recycling process. The key to this technology lies in the special
adhesive. The label can be removed by the waste sorter by washing the packaging in an
alkaline solution between 65°C and 80°C. It is important to note that wash-off adhesives
are not intended for removing labels in a dishwasher.
Besides the recycling
benefits, the appearance of wash-off labels is better than that of traditional wet glue
labels, which are still widely used in recycling processes.
How does the wash-off process work?
Currently, there are two major recycling streams that use wash-off labels: PET and
glass. Both streams use a specific adhesive.
PET packaging is shredded after
collection. Glass is recycled using the wash-off process without damaging the glass.
After collection, the packaging is washed in a warm alkaline solution between 65°C and
80°C. During this process, the labels float to the surface and carry away adhesive
residues and ink. The result of the process is pure PET, suitable for making new PET
packaging, or glass that can be refilled.
