There are usually hard capsules and soft capsules. Hard capsules, also known as hollow capsules, consist of two parts of the cap; soft capsules are processed into products with film-forming materials and contents at the same time. Hard capsules are classified according to the raw materials. The capsules generally include:
The capsule consists of two precision-machined capsule shells. There are many different capsule sizes, including 000#, 00#, 0#--5#=capsules. The capsule body part has a tapered edge, which can smoothly encapsulate the capsule on the high-speed filling machine. The double-locking ring system allows the capsules to be pre-closed before filling, and completely fitted together after filling with medicine. The design of the capsule also includes vents to avoid unnecessary air pressure inside the capsule during high-speed filling, which may cause rebound.
Plant capsules are hollow capsules made from plant cellulose or water-soluble polysaccharides to meet the needs of all-natural positioning and capsule formulation solutions. The capsule can also be colored and printed to present a unique customized appearance. It retains all the advantages of standard hollow capsules: convenient to take, effective in concealing taste and smell, and the contents are transparent and visible. At the same time, it has the connotation that traditional gelatin capsules do not have.
