Food quality depends not only on the physiochemical property of food, but also the unwanted temperature variation during storage and distribution, causing product failure through change of respiratory rate and microbial spoilage. Although, packaging materials play a significant role in controlling unwanted temperature changes, unwanted warming continues to occur due to low thermal buffering capacity and inadequate control of generated gases. Phase-change materials (PCM) are temperature-dependent substances that store and release latent heat energy during temperature-driven phase changes. However, the direct utilization of PCM for heat storage is limited due to leakage during the solid-liquid phase change process. In this study, we have introduced an approach for fabricating PP/PCM composite films for the successful utilization of shape-stabilized PCM and investigate the thermal properties and gas permeability of PP/PCM composites as a function of temperature and composition. |
