Application of the Capsule Shell
It can hold solid medications, protecting them from moisture, air, and light. It can also mask the bitterness, odor, and other unpleasant odors of the active ingredient.
Appearance of the Capsule Shell
The capsule shell consists of two overlapping lobes (capsule cap and capsule body). Each lobe has a rounded and closed end and an open end. The large-aperture capsule cap fits over the small-aperture capsule body, creating a tight seal when locked.
Capsule shells come in eight sizes, the most commonly used being 00#, 0#, 1#, 2#, 3#, and 4#. The smaller the capsule shell number, the larger the volume. Detailed specifications are shown in the table below:

There are many colors of capsule shells, such as red and yellow, blue and white, dark and light green, golden yellow, red and white, transparent, etc., as shown in the figure below:
Why are some capsules colored and the cap and body of the capsule different colors?
- Colored capsule shells are visually appealing and can mask the appearance of the drug itself.
- Color caused by sunscreens. Titanium dioxide can act as a sunscreen to treat some light-sensitive medications, thus creating a color.
- Two-color capsule shells help identify and distinguish capsules made through different production processes, preventing confusion.
- Healthcare professionals use different colors to easily distinguish medications.. Manufacturers use different colored capsule shells to easily distinguish capsule bodies and caps of varying sizes, thus preventing errors during mass production that could cause high-speed assembly line failures and result in losses.
Why are some capsules transparent?
The transparent capsule shell lets users see whether the contents are granules or powder, improving ease of use. Additionally, if some capsules deteriorate, the granules or powder inside may change, which serves as a reminder to users to check whether the contents of the capsule are safe and normal.
