Ordinary plastics have been produced and used for many years for packaging applications in various sectors. With the growth of the food industry, the demand for food packaging has also grown. However, the plastics made from petroleum are non-degradable, which has created severe bio environmental problems for the environment. Biodegradable polymers are an alternative approach to many industrial applications including food packaging, as well as risk control for non-biodegradable plastics. According to the type of the raw material, they are classified in one of the following categories: polymers extracted from biomass compounds, polymers synthesized from monomers and polymers produced from microorganisms. The quality of biopolymers depends on their physical, mechanical and thermal properties. The present study is an overview of the properties of different biopolymers and their compounds, comparing the properties of biodegradable polymers and biopolymers. The recent research works and innovative methods for the use of these plastics for food packaging and biomass plastic poisoning have also been studied and presented, concluding that biodegradable polymers help reduce the environmental impacts of plastics. It is worth mentioning that as the plastics from agricultural waste are used as raw materials for making this kind of packaging, there is a great opportunity to increase added value.
