Review Article: Development of biodegradable films using nanocellulose for food packaging application

Due to the development of nanotechnology and changing customer demands for food safety and hygiene, the food packaging indu s try is growing significantly. In today’s worldwide market, active packaging offers a number of advantages over traditional wrapping because of its capacity to absorb or release sub s tances to improve the shelf life of food. Traditional food packaging materials are difficult to recycle and are made from nonrenewable fossil fuels. The development of biodegradable films using Nano cellulose can be a good replacement for synthetic pla s tic packaging materials and can be a good solution for this problem. Other than that it has multiple advantages regarding tensile and physical properties, also as reducing health hazards. Tensile and physical characteri s tics are improved and water vapor permeability is decreased with the addition of cellulose nanoparticles to the biodegradable films/biodegradable composite films. The production of biodegradable materials employing Nano cellulose has been covered in this review s tudy in four different ways, including extracts from agricultural wa s te, rice husk, various plant extracts, and biopolymer composite material in food packaging. The reason for using Nano cellulose-based biodegradable films in food packaging is also reviewed in this article. The key points for future research in overcoming the problems related to Nano cellulose and biodegradable films are also predicted in the paper.
