Demand for products based on renewable raw materials is growing, thanks to increased environmental awareness among consumers. Rubber hotmelt adhesives, used in applications such as shipping and logistics, are no exception. TÜV Austria offers its “OK biobased” certification as an independent guarantee of the percentage of renewable content in products. Products can be certified as one-, two-, three-, or four-star bio-based, depending on their content.
The new certification applies to 98% of Avery Dennison’s rubber-based hotmelt adhesive volume. Most adhesives, such as S2045N, S2047N, and TS8000, received the 2-star certification (guaranteed minimum of 40% renewable content), while adhesives S2065N and C2075N received a 1-star certification (minimum of 20% renewable content). Note that the adhesive formulations remain unchanged.
