ABSTRACT
Research in the field of packaging materials demands the need for greener methods to reduce carbon footprint as well as to encourage green chemistry protocols. Several polymerized materials are being used in the field of packaging primal matter, which may cause environmental pollution and a rise in energy and resource demands. On considering this, researchers begin to focus on plant-based nano-cellulose, which have the capability for the preparation of materials for packaging. Cellulose is a biopolymer that is accessible in enormous amounts, with a fascinating combination of different properties. As established by several research groups, plant-based nano-cellulose is a biocompatible and nontoxic candidate whose rheological, mechanical and gas barrier properties are modest related to conventional oil-based plastics. Since polymer nanocomposites own unique material properties by combining the qualities of both nanofiller and polymer matrix, we can prepare cellulose-based nanocomposites by using cellulose as nanofillers. Such materials show an improved barrier property, increased heat distortion temperature, higher modulus and strength. This review discusses the synthesis, characterizations, properties and various uses of cellulose-based polymer nanocomposites in the packaging industry.
