Barrier films for food packaging are essential materials used to extend the shelf life of food products, maintain their quality, and protect them from environmental factors such as moisture, air, light, and contaminants. These films act as protective barriers between the food and the outside environment, reducing spoilage and preserving the freshness of the food. They are an integral part of modern food packaging systems, and their development has been driven by the growing demand for longer shelf life, convenience, and sustainable packaging solutions
