In recent days human beings are much concerned about healthy environment. They are becoming health conscious too, which lead to disposal of synthetic polymers based food packages and acceptance of bio packaging. Scientists and researchers are working on developing such bio packaging. These types of bio packages can be made from various types of biopolymers like polysaccharides; proteins and lipids. Protein based bio packages are mostly accepted because of its high degradability and their ability to supplement nutritional value to food products. Here in this review we are going to focuss on the techniques applied to make such protein based films, assessment of physical, mechanical, thermal, barrier and antimicrobial properties and also their applications in packaging food products.
