Enhancing antibacterial property: tetraethyl orthosilicate influence on quaternised chitosan/PVA film / Mohd Akasyah Sulaiman and Norin Zamiah Kassim Shaari

As a food packaging material, a biofilm barricades the food from contaminants. A film formulated from biopolymers with antibacterial properties is useful and holds high potential as a food packaging alternative since biopolymers are degradable, compostable, and made from renewable resources. Chitosa...
