This study presents a patented technology that makes insulation packaging from a corrugated board structure that fills packaging voids with a phase changing material (PCM). The filled panel, or sleeve, can be added to a standard shipping container as well as primary packaging to insulate the packaging. The temperature change of a chocolate bar wrapped with this insulation package is measured. In addition, Edge Crush (ECT) and Cobb tests are conducted to compare the ECT value of the insulation packaging to the conventional corrugated board.
