Development of A Comprehensive Biological Hazard ‐Proof Packaging Film with Insect‐Repellent, Antibacterial, and Antifungal Activities

AbstractA multifunctional film with insect ‐repellent and antimicrobial activities was developed. Star anise (Illicium verum Hook. f.) oil (SO) proved to be effective in repellingPlodia interpunctella (H übner) (Lepidoptera: Pyralidae) larvae and was selected as an insect‐repellent agent. Thymol, a compound that demonstrated strong growth inhibition activities against bothStaphylococcus aureus andPenicillium roqueforti, was selected as an antimicrobial agent. Based on the release profile test of SO using various plastic films, polypropylene (30 μm; PP 30) and low‐density polyethylene (20 μm; LDPE 20) were selected as laminated films for sustainable insect‐repellent and strong antimicrobial effects, respectively. Further, polyethylene terephthalate (12 μm; PET 12) was selected as an intermediate barrier layer. Finally, structure of t he multilayer film was designed as PP 30/SO/PET 12/thymol/LDPE 20. The developed film demonstrated insect‐repellent activity for>3 weeks, antibacterial activity for>2 weeks, and antifungal activity for 1 week. The results indicated that the developed multilayer film structure possessed strong, sustained insect ‐repellent and antimicrobial effects, providing a new possibility for the industrial applications to food packaging.Practical ApplicationA multifunctional active packaging film with insect ‐repellent and antimicrobial activities was developed. Star anise oil and thymol that showed insect‐repellent and antimicrobial ...
