The capsule type usually has a hard capsule and a soft capsule. Hard capsules, also known as hollow capsules, consist of two parts of the cap; soft capsules are processed into a product at the same time as the film-forming material and contents. Hard capsules are based on raw materials, and capsules generally include:Gelatin capsule and Plant capsule.
The capsule consists of two precision-processed capsule shells. Capsules come in a variety of sizes, including 000#, 00#, 0#--5#= capsules. The capsule portion has a tapered edge that smoothly encapsulates the capsule on a high speed filling machine. The double-locking loop system allows the capsules to be pre-trimmed before filling, and the cartridges are completely nested together after filling. The design of the capsule also includes venting holes to avoid unnecessary air pressure inside the capsule during high speed filling and cause bounce.
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 capsules can also be colored and printed to give a unique custom look. It retains the advantages of all standard hollow capsules: it is easy to take, effectively masks the taste and smell, the contents are transparent and visible, and it has the connotation of traditional gelatin capsules.
