Development of Chitosan and Polycaprolactone Based Trilayer Biocomposite Films for Food Packaging Applications

The mounting global concern over the environmental consequences of petroleum-based plastics has prompted significant research into sustainable alternatives, with bioplastics emerging as a forerunning solution. This systematic review elucidates the multifaceted synthesis processes of bioplastics, which are derived from renewable sources such as plant starches, cellulose, and waste materials. The synthesis encompasses stages from raw material selection, pre-treatment, to the incorporation of various additives, with the aim to achieve specific properties in the resultant bioplastics. A substantial focus of this review lies in comprehensively understanding the role of additives, which serve as the pivotal agents in tailoring the mechanical and thermal characteristics of bioplastics. Additives, including cross-linking agents, plasticizers, fillers, compatibilizers, and reinforcement agents, are critically examined for their influence on attributes such as tensile strength, flexibility, thermal stability, and biodegradability. Factors such as intermolecular interactions, hydrogen bonding, and moisture content, play a determining role towards the resultant properties. The prospects for bioplastics are rapidly expanding, signalling a transformative shift in various applications ranging from eco-friendly packaging to advanced biomedical devices. This article serves as a comprehensive guide to both researchers and industry stakeholders, providing deep insights into the synthesis of bioplastics and the transformative role additives play in their functional properties.

Chitosan (CH) films were prepared with/without glycerol as a plasticizer and coated with polycaprolactone (PCL) and cycloolefin copolymer (COC) to form bilayer films. The effect of the second layer coating on the physicomechanical properties of CH films was determined. The adhesion of PCL and COC solutions, when coated on CH film, was investigated by contact angle measurement. The contact angle of PCL film solutions was lower than COC film solutions (P <0.05). Scanning electron microscopy analysis revealed better compatibility between CH and PCL, while a phase separation was observed for CH/COC bilayers. Bilayers showed higher resistance to water when compared to neat CH film samples (P <0.05), while a reduction was found in tensile properties for bilayer films. Bilayer films had similar transmittance values with monolayer films (P >0.05). The physicomechanical properties of CH films significantly influenced by the addition of glycerol and application of the second layer.
