High freezing strength (high freezing power) alkaline gelatine (type B - B gelatine is bone gelatine or bovine skin gelatine treated with soaking ash) and acid gelatine (type A - A gelatine is pig skin gelatine or bovine gelatine without soaking ash treatment) can be used to manufacture hollow hard capsules. Both types of gelatin can be mixed or used alone.
Common Applications of Hard Capsules: Hard gelatin capsules are typically used to encapsulate dry powders or granules and are often used in the pharmaceutical and dietary supplement industries. Hard capsules provide a convenient and easy-to-swallow dosage form for a variety of products, such as vitamins, minerals, herbs, and medications. They also offer a degree of protection for the product, as well as a tamper-evident feature to ensure the safety and integrity of the medication.
