Abstract: The present disclosure relates to titanium dioxide particles designed to enhance reflection of both IR and visible wavelengths, or energy, and their use in forming cool, fully opaque polymeric articles prepared by melt processible resin. Such articles, made from melt processible thermoplastic and/or thermoset resin have enhanced outdoor utility because they inhibit damage caused by the sun as a result of the article including titanium dioxide particles of the present invention exhibiting low photo-activity properties.

Abstract: A new light protective package including a monolayer which includes treated TiO2 particles at high concentration levels of 6 wt % or higher of the monolayer, more preferably greater than 7 wt % of the monolayer, even more preferably greater than 8 wt. % of the monolayer, wherein the monolayer protects the food within the package from both light and physical damage. The monolayer has superior light protection properties while maintaining mechanical properties. The monolayer has a light protection factor (“LPF”) value of greater than 25, preferably greater than 30, more preferably greater than 40 or even more preferably greater than 50. The treated TiO2 material can be dispersed and processed in package production processes by use of incorporation with a masterbatch, and preferably processed into a package using blow molding methods.
