  6. Multilayer packaging material: Multilayer packaging consists of three layers: the barrier layer, the active layer, and the control layer. The barrier layer serves as a protective shield against substances that can degrade packaged food. The active layer contains ingredients like antioxidants and antimicrobials, which are released into the food at a controlled rate. The control layer regulates the release of active ingredients and safeguards the food. By adjusting material properties and structure, the release of active ingredients can be managed to prolong their effectiveness. Various techniques, including Layer-by-Layer (Lb.) assembly, electro-spinning, coating, and solvent-casting, have created multilayer films with desired release profiles for different active ingredients. These above-mentioned practices are mainly followed up by the food industry. Still, in India, small-scale businesses and street vendors also participate in using bio-degradable packaging practices such as tree-based plates and cutlery. Moreover, the traditional practice of using banana leaves in different regions of India is widely practiced by food vendors. It is not only environmentally friendly but provides health benefits as well.
