Abstract

Plastic is an integral part of our life and with the spread of COVID-19, it has become all the more important as packaging
materials for maintaining hygiene. Due to bioaccumulation and the detrimental effects of plastics, there is an urgent need for
alternatives. To restore our environment, this alternative has to be as comfortable as plastic material. As a result, in the recent past,
the concept of biodegradable plastics has gained much attention among researchers. The studies have reported polylactic acid
as an alternate material for plastics. The use of this polymer as an alternative is restricted due to its high cost and characteristics
such as thermal degradability and an inadequate barrier to oxygen and water. The present review gives a comparative evaluation
of biopolymers and their advantages and disadvantages as packaging material. The insight of this analysis will be suggestive of
designing sustainable food packaging biopolymers, which will further help in reducing its detrimental effect on the environment.
