This calculation evaluates the thermal integrity of insulated shipping containers used for transporting temperature-sensitive goods like pharmaceuticals. It determines if the phase change material's cooling capacity is sufficient to offset ambient heat ingress over a specific duration. The resulting safety margin ratio indicates whether the packaging design meets the required thermal protection standards.
