UV-VIS spectroscopy

In short — AI-generated

UV-VIS spectroscopy measures how much light a packaging material absorbs or transmits across the ultraviolet and visible light spectrum. A light beam is passed through the sample, and a detector records the intensity of the light that emerges on the other side.

The resulting data indicates the material's light-shielding properties, which is critical for protecting light-sensitive products from degradation. Packaging developers use these values to ensure that the chosen film or coating provides the necessary barrier against UV and visible light exposure.
