Packaging plays a major role in the protection and shelf life extension in the supply chain of a food product. Plastic based packaging has been widely used since decades. These materials made from petroleum based derivatives are expensive, takes many years for decomposing thereby polluting the environment. According to the report by Central Pollution Control Board of India (2013), about 15342 tons of plastic waste is generated every day across the country. Less than 5 % of the plastics are recyclable and the rest pollute the land and water bodies thus, affecting the fauna and flora. Dumping plastic wastes makes the harmful chemicals to leach down in the soil affecting the soil fertility and incinerating these wastes emits toxic gases, which are harmful to the environment. Recycling of plastic waste is not a permanent solution because of the additives and colour present. Hence, alternative packaging, which are eco-friendly, with a major emphasis to safe guard our environment is the needed measure to combat this issue. Such a packaging must be easily degradable. The term biodegradable refers to those materials that could be easily decomposed by the enzymatic action of the microbes within a short period of time. Polymers used conventionally as packaging materials, are not biodegradable because of the long chain molecules, which make the break down by the microorganisms difficult.1 Hence, they are considered as environmental waste. Contrary natural polymers have molecules easily degraded by the microorganisms.
Considering the adverse effect of petroleum based plastics causing environmental pollution, demand has risen for biodegradable packaging in the food sector. Biopolymers are molecules present in cellulose and proteins. They are produced from renewable sources such as plant based materials like starch, cellulose, plant oil, sugar, reed etc.
