Barrier films play a critical role in food packaging, as they serve to protect the contents from environmental factors that could negatively affect the quality, safety, and shelf life of food products. These films are specially designed to provide resistance against moisture, oxygen, light, and other contaminants, ensuring that food stays fresh, safe, and appealing to consumers. With growing concerns about food waste and the increasing demand for sustainable packaging solutions, barrier films have become an essential component in the packaging industry, particularly in the context of food preservation and the reduction of environmental impact. barrier films for food packaging
