Hard Capsules
Pharmaceutical gelatin is the main body of empty capsules, which consist of a cap and a body — two-piece capsule shells refined from pharmaceutical gelatin plus excipients.
Both high-gel-strength (high bloom) alkali-process gelatin (Type B — Type B gelatin is bone or cattle-hide gelatin that has undergone liming) and acid-process gelatin (Type A — Type A gelatin is pig-skin or cattle-hide gelatin that has not undergone liming) can be used to make empty hard capsules. The two types of gelatin can be used either blended together or on their own.
