Haze-Busting Colorants

OnColor PProTint and PProTintPlus colorants are formulated to mask the haze typical with polypropylene resins.

They let packaging converters exploit the technical and physical properties of clarified polypropylene without sacrificing clarity and transparency. The PProTint family is FDA compliant for use in pharmaceuticals, infant products, and certain food packaging.
