Evaluation of Light-Shielding Effect of Milk Cartons Using a UV-VIS-NIR Spectrophotometer

This application note examines the transmission characteristics of paper-based milk cartons using the UV-3600 ultraviolet visible-near-infrared spectrophotometer. The results of measurements conducted on the 3 types of milk cartons indicated differences in transmittance depending on the carton sample. Further, differences in transmittance were also found within each of the respective samples, depending on the measurement site.
