Capsules compared with the traditional capsule, the current plant capsule in some ways than the traditional capsule, such as resilience as traditional capsules, capsule sizes or traditional capsule varied, leakage, sticky and easily produced by extrusion deformation, this technology and production equipment for capsules put forward higher requirements. However, as you can see, capsules of raw materials are abundant, such as starch, malt extract carrageenan, cellulose, alginate, bee wax, some plasticizers, such as glycerol, sorbitol, maltitol, propylene glycol, polyethylene glycol and water. In view of the development of the gelatin, the traditional capsule (capsule of animal) is from the 30 's of the last century began to develop, and today form the pharmaceutical primary packaging form. Capsules of the research so far has only 20 years, over time, in terms of technology, equipment and raw materials after the breakthrough, capsules will play. Because, not only does it have a wide range of uses, there is better security.

Plants hollow fiber is the main raw materials, not only will breed bacteria and inhibits the growth of bacteria. Test results proved that plants hollow capsule placed in a normal environment for a long time, can keep the microorganisms within the scope of national standards.
