Composite packaging is a practical substitute for synthetic petroleum-based polymers, including polyethylene terephthalate, polyethylene, polypropylene, and polyethylene, due to their superior performance and environmental friendliness. Covalent or noncovalent connections, such as electrostatic, hydrophobic, hydrogen bonding, or van der Waals interactions, bring together active and matrix molecules to form composite packaging. The ability to integrate the unique properties of several materials is the main advantage of composite packaging. This results in improved mechanical strength, barrier qualities, biodegradability, and usefulness. The properties of composite packaging are affected by the kind and proportion of the materials used. Composite packaging may be enhanced with active ingredients such as antioxidants, minerals, and antimicrobials to provide additional benefits, including reducing lipid oxidation, inhibiting microbial development, and increasing nutritional value. Using these materials in food packaging allows for active and intelligent packaging, which has benefits including longer shelf life and real-time freshness indications. In addition, their biodegradable nature greatly aids in reducing plastic waste and achieving environmental goals. Common techniques for preparing composites, such as solvent casting and extrusion, are covered in this chapter. Research into composite packaging for perishable foods, including fruits and vegetables, focuses on its biodegradability, mechanical strength, and barrier properties.
