[nanoPost] Nano-dispersed Biopolymer to replace wax emulsions in packaging

Company Belgium

The company produces an environmental friendly, patented, nano-dispersed biopolymer to substitute wax emulsions in super hydrophobic paper and cardboard packaging.

The packaging industry is seeking easy recyclable and environmental friendly packaging solutions made of renewable resources. The company has developed an innovative biopolymer as a competitive, ecological substitute for wax emulsions used in the coating production of hydrophobic paper and board packaging.

The new biopolymer is of vegetable origin, while most used wax emulsions are produced from petrochemicals. This biopolymer shows other important advantages for the surface treatment of paper and cardboard compared to the use of wax emulsions.

The product requires no stabilizers even with a high solid content, while viscosity remains low (65% solids at +/- 300 cps with Brookfield 23°C 100 rpm spindel 5 ). Coating machines using the product can simply be rinsed with water. Furthermore, the product has a higher temperature resistance and is less sticky, which improves the handling of the treated paper and cardboard in production.

The product is approved for a wide variety of paper and board coating applications, both online and offline. The product contains a biopolymer with a monodisperse distribution of nano-particles with a regular shape.
