Method for producing antimicrobial nanofilms packaging cover based on titanium nano-dioxide through extrusion for extension of food shelf-life

A method for producing antimicrobial nanofilms packaging cover based on Titanium nano-dioxide through extrusion for extension of food shelf-life, the method comprising the step of:

• providing nano-silver and nano-clay particles;
• keeping oven at specific temperature to vaporize any trapped water between the nano-silver and nano-clay particles;
• inserting each vaporized nano-silver and nano-clay particles to a container;
• mixing the nano-silver and nano-clay particles with determined amount of Low-Density Polyethylene (LDPE);
• inserting the mixed LDPE with nano-silver and nano-clay particles to a twin extruder;
• and
• entering masterbatch to another extruder to synthesize a final nanocomposite film, wherein the blowing cold air is provided into the twin extruder to produce the final nanocomposite film.
