Claim One:
1. A method for producing a packaging design comprising: (a) providing a known homogeneous liquid sample comprising one or more known photosensitive entities at appropriate concentrations; (b) providing a cell having controlled optical properties to contain the sample at a controlled temperature between about −20° C. and about 100° C.; (c) providing a light source that generates a light beam with a controlled spectral signature between about 290 and about 1000 nm and a controlled intensity between about 0.01 and about 5 W/cm 2 ; (d) placing the sample into the cell, rendering a sample cell; (e) placing a first test material between the light source and the sample cell, rendering a shielded sample cell, wherein the light beam impinges upon the first test material and any penetrating light impinges upon the sample cell, and wherein the first test material comprises a known quantitative or qualitative property; (f) exposing the shielded sample cell to one or more light beam intensities for one or more durations; (g) measuring changes to the one or more photosensitive entities contained within the shielded sample cell at one or more durations to generate data points; (h) using the data points to determine a photoprotective performance value of the first test material; (i) repeating steps (a)-(h) with one or more additional test materials under the same conditions to generate one or more additional photoprotective performance values; (j) utilizing the two or more photoprotective performance values to generate a model for a class of materials that relates the known qualitative or quantitative property to the photoprotective performance; (k) using the model of step (j) to identify a photoprotective performance value of a packaging material; and (l) using the packaging material in step (k) to design a package.
