Gelatin soft capsules, which are also referred to as soft gels, come in various shapes such as round, oval, fish-shaped, and tube-shaped. They are a type of preparation that involves encapsulating oil or non-water-soluble liquids or suspensions that are insoluble in gelatin within a capsule shell.

   Gelatin is an excellent material for filling the contents of soft capsules. It effectively prevents the reaction between the capsule shell and the contents, leading to desirable biopharmaceutical properties. Currently, gelatin soft capsules are widely used in areas such as pharmaceuticals, nutritional products, cosmetics, and more.
