Thymol (2-isopropyl-5-methylphenol) is an essential oil
extracted from thyme (Thymus vulgaris), onions (Allium cepa), garlic
(Allium sativum) or other plants. It has been utilized as antimicrobial
agent in polymer film due to its efficiency and physical properties
suitable for blown film process. Numerous reports have
found the potential of thymol when it was incorporated in polymer
films. Rota et al. [15] concluded that thymol was an effective antimicrobial
agent for preserving the food spoilage and increasing the
shelf-life. Under microencapsulated condition, thymol showed
significant inhibited the Saccharomyces cerevisiae, Listeria innocua,
E. coli and S. aureus growths [16]. Although many literatures have
reported the antimicrobial efficiency of thymol but no report exists
in the PBS/thymol blends.
