Reducing environmental hazards from the use of synthetic polymers has led to the diversity and development of new technologies for packaging perishable products, including animal, poultry and aquatic products. Natural polymers in the form of edible films or coatings can be used to produce biodegradable packaging. Cellulose derivatives including methylcellulose, hydroxypropyl cellulose, hydroxypropyl methylcellulose and carboxymethylcellulose are among the most popular polysaccharide hydrocolloids used in the production of films and coatings. The sensory, nutritional and functional properties of edible film and coatings can be modified by various materials and methods. Also, various active compounds are placed in the film and coating solution to improve the quality, stability and safety of packaged foods. Therefore, when using edible films and coatings, it is necessary to consider both the physical properties of biopolymer materials and their functional properties. Cellulose derivatives have been used in the packaging of animal products including raw animal meat, poultry and aquatic products, meat products derived from them and eggs in the form of simple, composite and active edible films and coatings in order to maintain quality and increase shelf life. Legal, economic, cultural and marketing considerations must be considered in order to develop the use of biopackaging.
