Abstract :

Petroleum-based plastics or composite have created serious problems for the environment, and for this reason, researchers sought to produce alternative sustainable structures. Edible and degradable films were examples of materials that were produced and used for this purpose. Edible films are thin layers of edible material that can be placed on or between foods, but an edible coating is mainly placed on food products. Many studies have been conducted in this field for several years, but there is no comprehensive review in this field. The present study was conducted with the aim of investigating the performance of biodegradable films in food packaging. Various studies have used different materials such as starch, gelatin, chitosan, alginate, cellulose and etc. to produce biofilms, which, in addition to advantages such as biodegradability, have disadvantages such as weak mechanical and barrier properties. In this study, the effectiveness of biodegradable films in food packaging is investigated.
