  • PLASTIC-CONTAINING FOODSTUFF CONTAINERS USING IRREVERSIBLE THERMOCHROMIC MATERIAL TO INDICATE PAST EXPOSURE TO ELEVATED TEMPERATURES
    Publication number: 20160194132
    Abstract: An article includes a foodstuff container comprising a plastic, and a container component containing an irreversible thermochromic material configured to undergo a permanent color change responsive to exposure to temperatures above a threshold range. A system includes an optical scanner to capture imagery of a batch of foodstuff containers, at least one foodstuff container of the batch comprising an irreversible thermochromic material configured to permanently undergo a color change after exposure to temperatures above a threshold temperature range. The system also includes an image processing system to analyze the imagery to determine whether a foodstuff container of the batch has thermochromic material that has permanently undergone the color change.
