  1. What is Functional Coating & its Role in Food Packaging? Functional coatings play a pivotal role in the realm of food packaging, offering a dynamic range of capabilities that transcend traditional packaging materials. These coatings are engineered to enhance protection, preservation, and presentation, ensuring that food products are delivered to consumers in optimal condition while simultaneously addressing key industry challenges. Let us find out the role of functional coatings in food packaging: 1.Barrier Properties: Functional coatings are often used to enhance the barrier properties of packaging materials. They create a protective layer that acts as a barrier against external factors such as moisture, oxygen, light, and contaminants. These barriers help extend the shelf life of food products, preserving their freshness and quality. 2.Moisture Resistance: Moisture can be a detrimental factor for many food items, leading to spoilage, texture changes, and microbial growth. Functional coatings can provide moisture resistance, preventing the ingress of water vapor and maintaining the product's desired moisture content. 3.Oxygen Barrier: Oxygen is a major contributor to food deterioration, causing oxidation, rancidity, and flavour loss. Functional coatings can include oxygen barrier properties, reducing the transmission of oxygen into the packaging and protecting the product from these harmful effects. 4.UV Protection: Some functional coatings are designed to offer UV protection, shielding food products from harmful ultraviolet radiation. UV rays can lead to photochemical reactions, degrading the quality of food, and compromising its safety. 5.Odour and Flavour Retention: Functional coatings can help retain the aroma and flavour of food products. They prevent the escape of volatile compounds responsible for taste and smell, ensuring that the product tastes and smells as intended.

  2. 6.Anti-Microbial Properties: In some cases, coatings with antimicrobial properties are used to inhibit the growth of harmful microorganisms, extending the shelf life and safety of perishable foods. 7.Heat Resistance: Functional coatings can provide heat resistance, allowing packaging materials to withstand high-temperature processing methods such as sterilization, pasteurization, and hot filling. In conclusion, functional coating in food packaging is a versatile and essential technology that enhances protection, preservation, and presentation of food products.
