As one of the core forms of modern pharmaceutical and health care product packaging, the principle and production process of gelatin capsules have important application value worldwide. Gelatin capsules are made of natural gelatin or plant-based materials, and are usually divided into two categories: hard capsules and soft capsules. They are widely used in the outer packaging of medicines, health care products and functional foods.
The basic principle of gelatin capsules is to form a hollow capsule shell through the hydration and drying process of gelatin to encapsulate active ingredients. Hard capsules consist of two parts: the cap and the body, which are made through precise mold forming and drying processes. Its hollow structure allows precise metering of fillers and dissolves in the digestive tract to release the contents. Soft capsules use a dripping or pressing process and are often used to encapsulate liquid or semi-solid ingredients such as fish oil, vitamin E, etc.
The solubility of gelatin capsules is one of its key characteristics. Gelatin dissolves rapidly in the pH environment of the human stomach to ensure efficient release of the contents. In addition, gelatin capsules have good barrier properties, which can prevent the degradation of active ingredients by oxygen, moisture and light, and extend the shelf life of the product.
In the foreign trade market, the demand for gelatin capsules continues to grow, especially in Europe, America and Asia. With the improvement of health awareness, consumers have an increasing demand for natural and pollution-free packaging materials, which has prompted gelatin capsule manufacturers to optimize production processes and develop alternatives such as plant-based capsules to meet vegetarian and religious dietary needs.
In addition, the standardized production process and strict quality control system of gelatin capsules make it a reliable choice in cross-border trade. Exporting companies need to comply with international standards, such as GMP certification and FDA requirements, to ensure product safety and market competitiveness.
Gelatin capsules are still one of the first choices for global pharmaceutical and health care product packaging due to their high efficiency and safety. With technological innovation and diversification of market demand, its application prospects in the field of foreign trade remain broad.
