Biodegradable films from poly (lactic acid) (PLA)-chitosan-polyethylene glycol (PEG) : fabrication and evaluation of mechanical properties

In this research, the production of biodegradable plastic food packaging from biopolymers poly (lactic acid) (PLA), chitosan and polyethylene glycol (PEG) was investigated. In addition, the objective for this research also wants to study the mechanical properties of biofilms at different percentage...
