CESA-natur light masterbatches provide light stabilization in both conventional polymers and biopolymers. They can also function as an ultraviolet filter to protect the contents of packaging made of bioplastics such as polylactic acid (PLA). Like synthetic additives, they are based on aromatic molecules, but the CESA-natur UV masterbatches use naturally occurring ingredients.
