In this work, low density polyethylene (LDPE) films were loaded by scCO2-assisted impregnation with R-(−)-carvone, the main component of M. spicata and A. polystachya essential oils with antimicrobial and insecticidal activity. Impregnation runs were performed in a lab-scale high-pressure cell, and the effect of CO2 density (240–700kgm−3) and temperature (35–60°C) on impregnation yield was evaluated...
