What is Empty Capsule?
An empty capsule is a small container made of gelatin or a similar substance, intended to hold a medicine or drug powder, granules, or liquid. These capsules are designed to be filled by pharmacists or manufacturers with the appropriate dosage of medication before being administered to patients.
What You Need to Know About Empty Capsule — Main Materials
Empty capsules are cylindrical and consist of a cap and body that fit and lock together, forming a hard yet elastic empty shell, widely used in the preparation of capsule formulations in the pharmaceutical and health product industries. Empty capsules are made from primary materials and auxiliary materials. The primary material for empty capsules is generally food-grade or pharmaceutical-grade high molecular weight film-forming materials, which contain a certain amount of moisture. When needed, based on different film material characteristics, different preparation processes, and user demands, a very small amount of food-grade or pharmaceutical-grade adjuvants, such as colorants, light blockers, plasticizers, and gelling agents, may be used.
As science and technology have advanced, the emergence of new materials and improvements in process technology levels have led to the development of empty capsules from originally just gelatin-based to now including hydroxypropyl methylcellulose (HPMC) capsules, hydroxypropyl starch capsules, and pullulan capsules. The corresponding main materials for these capsules are gelatin, hydroxypropyl methylcellulose, hydroxypropyl starch, and pullulan. Below, we introduce these four main materials in terms of their sourcing, regulatory compliance, and material properties to help you choose the right empty capsules.
Gelatin
Gelatin is an animal-based material derived from partial acid, alkaline, or enzymatic hydrolysis of collagen found in animal skin, bones, tendons, and ligaments, or a mixture of these different types of gelatin. Gelatin does not exist freely in nature and cannot be extracted from the non-collagenous parts of vertebrates such as horns or hooves. Gelatin has no plant sources and no chemical relationship with other materials known as vegetable gels (such as seaweed extracts). Extracted from collagen, it contains a significant amount of cyclic amino acids, proline, and hydroxyproline. Collagen consists of three intertwined helical polypeptide chains connected by intermolecular cross-links.
Hydroxypropyl Methylcellulose (HPMC)
Hydroxypropyl methylcellulose is a plant-based semi-synthetic product made by partially methylating and hydroxypropylating cellulose. Its production involves treating cotton linter or wood pulp cellulose with caustic soda, followed by sequential etherification with chloromethane and epichlorohydrin, and then refining and milling the product.
Hydroxypropyl Starch
Hydroxypropyl starch is a plant-based semi-synthetic product made by chemically hydroxypropylating modified starch. Its preparation method involves starch undergoing etherification reactions with epichlorohydrin under alkaline conditions, followed by refining and milling.
Pullulan
Pullulan is a natural water-soluble polysaccharide made from starch syrup by fermentation. It consists of maltotriose units (three glucose molecules connected by α-1,4 bonds) linked by α-1,6 glucosidic bonds.
Pullulan, CAS Reg. No. 9057-02-7, is recognized by the FDA as GRAS and is listed in the 2023 edition of the United States Pharmacopeia.
Pullulan is used in food and pharmaceuticals as a film-forming agent, adhesive, binder, and thickener. It is odorless, tasteless, and stable. Pullulan films have very low oxygen permeability, which helps protect the active and functional ingredients within the films from degradation. Pullulan produced under the conditions of the USDA’s National Organic Program (NOP) can be certified as an organic product.
Capsules can mask the bitter taste and odor of drugs and eliminate the unpleasant experience of patients when taking them.For example, most antibiotics have a bitter taste. Chloramphenicol is known to have a bitter taste.
Some drugs in the stomach is easy to be destroyed or have a strong irritation to the stomach, often made into enteric capsules, to ensure that the capsule reached the alkaline duodenum to dissolve.If the capsule is opened and swallowed, it will reduce or even lose its efficacy, and increase the irritation to the stomach, even causing stomach bleeding.

There is a prescribed dose of the drug in the capsule, and it is easy to remove the powder after stripping, resulting in inaccurate dosage, which is not conducive to treatment.
Some capsules are slow-release capsules, which must be swallowed completely in order to release the drug at a balanced dose and give full play to the optimal efficacy.If you peel the capsule.Pouring the drug out and taking it will destroy the sustained-release properties of the capsule and fail to achieve the purpose of sustained-release.
How To Replace Capsule Mold On The Empty Capsule Filling Machine




Preparation: Before starting, ensure that the appropriate capsule molds for the desired capsule size and type. Check the capsule size printed on the capsule tooling to avoid mistakes (0#,00#, etc.). Keep the capsule tooling clean and free from any residue or contaminants. Many factories don’t pay serious attention to the cleaning issue, which leads to a shorter service life of capsule mold.
Positioning: Locate the mold housing area on the capsule filling machine. This is where the mold will be inserted. Typically, there are designated slots or compartments for capsule mold placement.
Alignment: Insert the capsule mold into the designated slot, ensuring that it aligns properly with the machine’s alignment pins or guides. The mold should fit snugly into place without any forceful movements.
Securing: Once the mold is positioned correctly, secure it in place according to the machine’s instructions. This involves tightening screws, latches to ensure the capsule mold remains firmly fixed during operation.
Verification: Double-check that the capsule mold is securely installed and properly aligned within the machine. Ensure there are no loose parts or potential hazards that could affect the capsule filling process.
Testing: Before using the machine for actual production, perform a test run with empty capsules to validate the proper functioning of the capsule mold. Check for any abnormalities or misalignments during the trial process.
