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.
