Abstract: A new light protective rigid monolayer package which includes TiO2 particles, at least one color pigment selected from black and yellow, and a polymer. The light protective rigid monolayer package can have an LPF value of at least about 20.

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.

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: Methods and apparatus for quantification of photoprotective performance of packaging concepts in an accelerated timeframe are disclosed. In certain embodiments, the apparatus includes a light source which provides a light beam that impinges upon a photoprotective material before being transmitted to a sample cell of a photosensitive entity, such as a photosensitive nutrient. In certain embodiments, the apparatus and methods can be used to generate models for the prediction of photoprotective performance values of untested materials based upon some other known qualitative or quantitative property.

Abstract: Titanium dioxide pigment particles with treatment of an organosilicon compound and boric acid and/or boron oxide is disclosed. The product has a greater resistance to becoming discolored upon exposure to ultraviolet light when incorporated in polymers, particularly polyolefins such as polyethylene.
