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.

Abstract: The present invention is based on a surprising discovery of new packaging materials used to package substances, such as foods, preventing the photo-oxidation of entities found in these substances. Specifically, these new packaging materials include a mixture of polymer resins having novel and specific ratios of filler, preferably calcium carbonate, and titanium dioxide resulting in the material having unexpected properties.
