Silver Nanoparticle Filled HPMC and Xanthan Films for Food Packaging and Safety

Majority of materials employed for food packaging are non-bio-degradable. This however does not meet escalate demands in society for sustainability and environmental safety. Many biopolymers have been exploited to develop biodegradable food packaging materials. Regardless, the usage of biopolymers has been limited due to the poor mechanical and barrier properties. To enhance these properties, Silver nanoparticles were synthesized by sodium borohydride using reduction method and are doped into bio-composite membrane of HPMC and Xanthum gum to form bio-nanocomposite membrane. SEM, TEM, FTIR, UV-VIS spectra and XRD can be done to have characteristic peaks of Nano-bio-composite membrane. This composite film is studied for its mechanical solubility, thermal, structural and antimicrobial property
