Film coatings are thin layers applied to the surface of tablets, capsules, or other pharmaceutical products. These coatings serve various purposes, such as improving the appearance, masking unpleasant tastes, and protecting the active ingredients from environmental factors like moisture and light. In addition to pharmaceuticals, film coatings are also used in the food and electronics industries. For example, in food products, they can enhance shelf life and maintain freshness. In electronics, film coatings can provide insulation and protection against corrosion, ensuring the longevity and reliability of devices.
