Update:11 Oct 2021

Vegetarian hollow capsules are mainly classified according to the types of film-forming agents.

The film-forming agent is a polymer that can form a continuous film in a plain hard capsule, and generally accounts for the largest proportion of the ingredients in a plain hard capsule. The most researched vegetarian capsules at this stage are the polysaccharide capsules based on pullulan and seaweed polysaccharides, the starch capsules with modified potato starch, corn starch, and tapioca starch as the main raw materials, and the starch capsules with hypromellose as the main raw materials. HPMC capsules.

Vegetarian capsules with HPMC as the main raw material are the least difficult to promote. HPMC hollow capsules are easier to form films and more stable than other types of hollow capsules. HPMC capsules can maintain stable hardness, elasticity and appearance properties under different temperature and humidity conditions.

Starch hollow capsules have good stability and the lowest basic cost. But because of its fragility, it is not easy to produce.

Pullulan hollow capsules are brighter. However, due to its sensitivity to humidity and temperature, it cannot be widely used. This is currently the most expensive vegetarian capsule.

HPMC hollow capsules are currently the most popular and widely used plant hollow capsules in the world.
