Everything you need to know about durable wash-off labels 

Wash-off Labels
In the effort to be more eco-friendly, brands are always looking for ways to improve their packaging. Wash-off labels are a striking and revolutionary trend in the packaging industry. But what exactly are wash-off labels, 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 its unique 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's worth noting that wash-off adhesive isn't meant for use in dishwashers.
Apart from their recycling advantages, wash-off labels look more appealing compared to traditional wet adhesive labels, which are still commonly used in recycling.
How Does the Wash-off Process Work?
Currently, wash-off labels are used in two main recycling streams: PET and glass. Each stream requires its own specific adhesive.
PET packaging is shredded after collection, while glass is recycled using the wash-off process without damaging it. In the wash-off process, collected packaging is washed in a warm alkaline solution between temperatures of 65 °C and 80 °C. During this wash, the labels float to the surface, carrying adhesive and ink residues with them. The result is pure PET, suitable for making new PET packaging, or clean glass that can be refilled.
Choosing wash-off labels not only reduces waste but also contributes to creating more sustainable packaging, benefiting the planet.
