anocrystals (NCchit) and nanofbers (NFchit) extracted from chitin are considered as nanomaterials of great innovative

potential and promising biomaterial for academic and industrial felds. The research related to their production and application

is still new. In the other hand, in recent years, many research programs have focused on developing more and more bio-degradable

packaging of natural polymers. Among them, the one based on polysaccharide polymers is hydroxypropylmethylcellulose

(HPMC). This is the frst study to investigate the compatibility and reinforcement effect of nano-size chitin fllers (NCchit and

NFchit) on hydroxypropyl methyl cellulose (HPMC). NCchit aqueous dispersions were prepared by acid hydrolysis of commercial

shrimp shell α-chitin while NFchit were prepared by mechanical defbrillation using closed loop grinding. The average widths and

lengths of NFchit were (8.7±3.17) nm (673.9±263.3) nm respectively while for NCchit were (9.7±3.2) nm and (243.5±55.1) nm.

Composites of HPMC with different loadings of NCchit or NFchit were prepared by casting technique, using water as solvent. The

effect of morphology and size of each nanomaterial on morphology, transparency, mechanical, thermal and barrier properties

of the resulting nanocomposites were investigated using various techniques. The obtained results revealed the positive effect

of both nanomaterials on HPMC by enhancing its mechanical properties. The nanocomposite flms exhibited better oxygen

and water barrier with slight decrease in transparency than control HPMC flm. Overall, chitin NCchit offer superior reinforcing

performance than chitin NFchit.
