Preparation, characterization and fire resistance evaluation of a novel ceramizable silicone rubber composite

AbstractComposites made of poly(l?lactic acid) (PLLA) and ??cyclodextrin/D?limonene inclusion complex (CD?Lim) are prepared to develop novel food packaging material with antibacterial properties. The composites are formulated with bio?based materials that are also biodegradable. The addition of CD?Lim to PLLA results in enhanced permeability and water uptake. Optical properties of PLLA/CD?Lim composites also significantly vary compared to plain PLLA, with partial loss of transparency and gloss, but sizably increased barrier to UV light, which imparts protection from oxidation to lipid?containing food. The mechanical properties of the composite films are also affected by composition. Most notably, PLLA films containing CD?Lim display significant antibacterial and antifungal properties, proving their potential as active food packaging films.
