Frequently asked questions

End of Cap
It is the main part bearing closing pressure during locking motion. Its thickness must bear closing force of the filling machine to prevent dent.

Hemispherical End
This section also needs to bear closing pressure during locking motion.

Body Thickness
Thickness must be within specifications for enabling to perform smoothly during filling process and to have a close fit between the walls of cap and body.

Edges
Smoothness of cutting edges can affect the capsule filling performance.

Tapered Rim
The tapered rim design on the body allows for telescope-free encapsulation, especially on the high speed capsule filling machines.

Locking Rings
They are designed to be close-fitting during Locked status and to prevent from separation or content leakage.

Dimples
They are designed to gently engage with indented ring of the body during Pre-Locked status.

Air Vents
They are designed to release the compressed air inside capsule occurred during filling process.

Capsule are package materials for the pharmaceutical and health food which can protect their contents. Empty capsules must be properly stored in a good temperature and humidity environment before filling process to ensure the quality.

Storage Condition

 Temperature: 15~25℃

 Relative Humidity: 35~65%

Storage Suggestion

 Direct sunlight should be avoided.

 Keep away from water or high humidity environment; store in a cool and dry place. 

 Remainder capsules should be tightly sealed within an aluminum foil bag to avoid further change in quality.

Shelf Life 

Under recommended storage condition, both of our gelatin and vegetable capsules will maintain their quality for 5 years from the manufacture date. We have confirmed this result from our stability tests.

The Capsule Filling Capacity table is shown as above.  Size#00EL is our largest capsule and its filling capacity is 1.04ml.  Size#4 is our smallest capsule and its filling capacity is 0.21ml.  The filling capacity for different size of capsules is depends on the density of capsule contents.  When the density is bigger and the powder is finer, the filling capacity is larger.  When the density is smaller and the powder is bigger, filling capacity is smaller.

The most popular size in Taiwan is #0, for example, if the specific gravity is 1g/cc, the filling capacity is 680mg.  If the specific gravity is 0.8g/cc, the filling capacity is 544mg.  Best filling capacity requires suitable capsule size in order to perform smoothly during filling process.
If filling too much powder, it will let capsule become un-locked situation and content leakage.  Normally, many health foods contain compound powders, so their particles have different sizes.  Therefore, choosing specific gravity at 0.8g/cc as a filling capacity standard is much safer.
