Soft Gelatin Capsule Introduction:
  
 

Soft gelatin capsule has being more and more widely applied in various fields of drug, nutriceutical and cosmetic. The soft gelatin capsule is a sealed capsule usually filled with liquid and has a fortified and tough shell consists of gelatin and glycerol. Soft gelatin capsule is used to encapsulate liquid, suspension, paste or particle quantitatively in sealed capsules of various size and shape.
Different from the two-step manufacturing (shaping and filling) of hard gelatin capsule, the soft gelatin capsule is made on a rotating mould in a continuous one-step operation. Gelatin skin made of gelatin and glycerol passes through two die rolls facing each other and continuously rotating in reverse cycles and forms in shape in the mould cavity. The size and shape of the soft gelatin capsule are determined by the mould cavity. Material filling and sealing of gelatin skin is carried out in the same time so that the filling process ends right before the finish of sealing.

Filled capsule is put into tumble dryer for forming and drying, and then it is cleaned and dried finally. After visual inspection, the capsule is packed up and stored in the warehouse.
