Abstract

Environmental concerns about the use of non-renewable raw materials and non-biodegradable waste production have increased exponentially in recent decades. Phase change materials respond to temperature variation and have been used for helping thermal control in fabrics and building materials. In this work, we demonstrated the potential of paperboard functionalized with phase change material (PCM) particles with a melting point at 79 °C aiming to obtain thermo-active properties. Thus, the package was designed based on sustainable materials as an alternative for the maintenance of high temperatures in food products. We systematically performed kinetic experiments varying the mass fractions of the particles in two distinct cooling conditions: air inside and oil inside. The thermal response was dependent on the amount of PCM particles, and the temperature of the product was kept longer during cooling in relation to the original paperboard. A remarkable difference was observed in the response time of material treated with PCM that took about 10 min more than paperboard to reach the temperature from which the sample was to be cooled. The results presented in this work expand the applicability of PCM particles for extrusion conditions and open new opportunities for thermo-active materials.
