There are two main types of capsule shells on the market, soft capsule shells, and hard capsule shells. The main raw materials of both are food-grade medicinal gelatin and starch. The main ingredients are roughly similar, and both are harmless materials that can be absorbed by the human body. Capsule shells are currently widely used in the medicine and pharmaceutical industries.

    The hard capsule shell is mainly made of food-grade medicinal gelatin, which is refined and made of auxiliary materials. Edible gelatin itself is a water-soluble protein extracted from collagen, which is the main natural protein component in connective tissue. The medical hollow hard capsule shell is mainly used to hold solid powder and granular drugs and has good bioavailability, and can dissolve quickly, reliably, and safely. The capsule shell also solves the deficiencies of difficult entrance and poor mouthfeel for the user.

    Soft capsule The soft capsule material is made of gelatin, glycerin, or other suitable pharmaceutical excipients alone or mixed together. A soft capsule is a kind of capsule made by sealing liquid medicine or liquid and solid medicine in soft capsule material
