German manufacturer of vinyl acetate/ethylene-based (VAE) dispersions for adhesives Wacker has developed a novel product specifically for the paper and packaging industry. Vinnapas XD 05 – is a cost-effective and sustainable alternative to existing packaging adhesives based on polyvinyl acetate (PVAc).
In adhesive formulation, a VAE-based product is said to make it possible to reduce the amount of extra additives. It is also characterised by high setting speed and good machine processability, according to Wacker, making it ideal for formulating packaging adhesives - especially for food applications due to the extremely low migration potential.
A further benefit claimed for the new dispersion is that additional additives such as plasticisers can be eliminated in the formulating of adhesives. This simplifies formulation and increases manufacturing productivity – and means that the product meets the latest environmental and safety standards.
