Enhancing barrier properties of chitosan extracted from shrimp shells as a sustainable material for active packaging using natural wastes

Due to the environmental concerns, much responsiveness has been paid to natural polymers and recycle wastes. Disposal of wastes like marine wastes and domestic wastes end up in landfills and open areas which cause environmental crisis. The development of biodegradable active packaging materials is one of the alternatives to reduce the using of synthetic petroleum-based plastics. Biodegradable films are made from biopolymers that were shown to have affinities in improving the shelf life of food product. © 2021 Nova Science Publishers, Inc.
