“…Synthetic polymers used as food packaging materials have several concerns including nonbiodegradability, diminishing oil resources, environmental apprehensions for their disposal or incineration, and toxicity to living organisms (Dehnad, Mirzaei, Emam‐Djomeh, Jafari, & Dadashi, ). To overcome these serious problems, many researchers are now focusing on the application of various biopolymers with ecofriendly nature, biodegradability, selective permeability to gases (CO 2 and O 2 ), nontoxicity, good film‐forming ability, and biocompatibility properties, such as carboxymethylcellulose (Rezaei & Shahbazi, ), poly‐lactic acid (PLA) (Rezaeigolestani et al, ; Shavisi, Khanjari, Basti, Misaghi, & Shahbazi, ), gelatin (Bodini, Sobral, Favaro‐Trindade, & Carvalho, ), alginate (Hao et al, ), and particularly chitosan (CH) (Ojagh, Rezaei, Razavi, & Hosseini, ; Siripatrawan & Noipha, ).…”
