Unilever patents a method to be able to generate packages with
recycled material whose color is analogous to virgin
10/04/2021
By using recycled material, the same color is not usually achieved as with virgin.
It has also been achieved using NIR detectable dyes. 95% recycled PE.
Layered structure, with the thin internal non-colored recycled plastic and the thick external colored plastic (50%). Inside, the carrier is a recycled bioplastic, oil or resin. The internal one reduces the bad smell that is associated with the colored recycled resin. |
