Hard gelatin capsules can exhibit defects during production or filling, such as:
Cracks: Caused by improper drying or excessive brittleness of gelatin.
Deformation: Due to improper storage conditions (e.g., high humidity).
Leaks: From improperly sealed liquid-filled capsules.
Uneven Thickness: From inconsistent gelatin coating during dipping.
Capsule Separation: Caused by poor fitting of cap and body.
Prevention of Manufacturing Defects:
Optimizing manufacturing parameters (temperature, humidity, viscosity).
Regular inspection of equipment and raw materials.
Ensuring proper storage conditions.
