Starch And Cellulose Based Bio-Polyethylene: A Review

ABSTRACT

In current year, there has been enhancing in the usage of plastic and disposal of waste coming from daily life. Various type of plastics are using for our daily needs, in order to reduce the impact of petroleum based plastics and other waste to be considered and focused on green plastics. Polyethylene are the polymers which can be produced by repeating the single units. It is one of the bittersweet coinage for human's better life. But this coinage causes a lot problems to the environment. To overcome this problem an alternative and eco-friendly Polyethylene is introduced called bio- polyethylene. Bio-polyethylene are from natural biomass sources. Among various source, starch has chief role in production of bio-polyethylene due to its low cost and nature abundance with plasticizers such as glycerol and vinegar. Starch based bio-polyethylene has good mechanical properties, tensile strength and biodegradability. Cellulose also used as source in development of biodegradable polyethylene. In this review starch and cellulose has led to their great innovative uses in food packaging and to improved biodegradation and mechanical properties.
