Hard Capsule - Overview

 

 

Hard capsules are also known as hard gelatin capsules and are generally employed for the encapsulation of solid oral dosage forms. These capsules are perfect for enclosing highly concentrated active substances and are available in various sizes, thus suitable for both medicine and vitamins.

 

Advantages of Hard Capsule

 

Shortened development time
Compared with tablets, hard capsules generally require fewer manufacturing steps, allowing for faster product development.

 

Protection of filling
Physical factors in the manufacturing process that can cause quality deterioration, such as heating and pressure, can be reduced. In addition, the amount of additives used can be reduced.

 

Masking effect
Masking the bitter taste and odor of the filling contributes to improved treatment compliance.

 

Various types of filling
Hard capsules can be filled with two or more types of solid preparations such as granules, tablets and mini tablets. Oily liquid preparations and semi-solid preparations can also be incorporated into capsules by band sealing.

 

Enhanced distinguishability
Hard capsules can be colored or printed to make them stand out. A wide variety of colors can be created by using tar dyes, natural dyes, and titanium oxide. Text, marks, or other graphics can be printed in the specified ink color.

 

 
 
Composition of Hard Capsule

Since hard gelatin capsules are used to house compounds usually in powder or granules, they need to be made of the appropriate materials. Primarily, these are:

Gelatin

Their primary component, gelatin comes from bovine or cattle, and pigs or porcine. Gelatin is used since it dissolves more efficiently in water even at higher temperatures, producing a gel when cooled down. This material, which comprises about 40 percent of hard gelatin capsules, are also resistant against harsh environmental conditions.

Additives

Aside from gelatin, this type of capsule also contains colorants, plasticizers, and preservatives, collectively referred to as additives.

Preparation of Hard Capsules (Hard gel)

The preparation of hard capsules includes identification of appropriate shell,preparation of filling content,filling and encapsulating. Empty shells can be chased from appropriate manufacturers. Empty shells are comprised of gelatin,plastisizers and water,as well as accessory components like colorants,antiseptics and light screening agents. While the production of hard shell capsules requires two separate machines—one for the shells and another for the filling—the production of soft gelatin capsules only requires one equipment for the feeding and sealing steps.

 

Gelatin capsules are prone to hardening upon dehydration,softening upon hydration and react with aldehydes.Therefore,they require more stringent controls for storage temperature,humidity and package materials. In order to overcome this problem,shell made from botanical polysaccharides and dietary fibers such as starch capsules, methyl cellulose capsules,are employed as a substitute for gelatin capsules.Furthermore,botanical capsules are more stable with less inter-individual variations,highly flexible and able to withstand higher temperatures.

 

 

Other Services

 

 

Product Development
Our custom capsule supplement formulation team selects optimal excipients to create powder blends with ideal flow characteristics and content uniformity. We determine the appropriate capsule size, composition (gelatin or vegetarian HPMC), and color based on formulation volume and target consumer preferences.

 

Ingredient Sourcing
Our procurement specialists select premium ingredients specifically suited for capsule applications, validating each component through comprehensive quality verification. Through our capsule supplement manufacturing process, we source specialized excipients that enhance powder flow and prevent segregation of active ingredients during manufacturing. For capsule shells, we select pharmaceutical-grade materials from certified suppliers with documented consistency and dissolution performance.

 

Packaging and Label Design
Our packaging team develops container solutions optimized for capsule stability, focusing on moisture protection critical for maintaining shell integrity and powder stability. We evaluate specialized options including desiccant systems, enhanced barrier materials, and child-resistant features based on your product requirements and target consumer. Our design specialists integrate these functional elements while showcasing your brand identity effectively.

 

Encapsulation
Our precision encapsulation process utilizes automated technology that ensures consistent fill weight and content uniformity in every capsule. We implement validated protocols for powder feeding, capsule filling, and weight verification calibrated to your specific formulation's characteristics. Our capsule supplement manufacturing specialists monitor critical parameters including powder density, machine settings, and environmental conditions throughout the encapsulation process.

 

Packaging
Our automated counting and filling technology ensures accurate container counts while minimizing handling that could damage capsules. Integrated inspection systems verify closure application, seal integrity, and final packaging appearance. This precision approach guarantees your capsule supplements maintain quality throughout distribution channels while presenting professionally at the point of purchase.

 

Testing
Our comprehensive testing program validates your capsule supplement's identity, potency, and performance characteristics. Through our custom capsule manufacturing process, we implement specialized analytical methods optimized for your specific active ingredients to verify concentration and uniformity. Physical testing includes weight variation analysis, disintegration timing, and dissolution profiling that predict in-vivo performance.

FAQ

 

Q: What kind of gelatin is used in Hard Capsules?

A: The primary gelatin types used in capsules are typically from bovine or porcine raw materials. Depending on the fill, formulation and target market group, manufacturers have flexibility in the raw material type, with some opting for a combination of porcine and bovine options. Bovine bone gelatin, for example, contributes to capsule firmness. Porcine, on the other hand, offers plasticity and a non-opaque finish.

Q: What are Gelatin Hard Capsules used for?

A: Gelatin hard capsules are ideal for powdered or granulated fillings. Pharmaceutical ingredients or bioactive ingredients can be easily filled into two-piece hard capsules and allow precise dosage.

Q: How long does it take Hard Gelatin Capsules to dissolve?

A: Under normal conditions, a standard gelatin hard capsule dissolves in the stomach within 20 to 30 minutes after swallowing. Different types of gelatin or additional processing steps can affect the time it takes for the active ingredients to be released.

Q: Is there a standard size of Hard Gelatin Capsule?

A: Empty capsules are available in a variety of sizes. There is no standard size for hard gelatin capsules, but most capsules are size 0 or 1. Capsules are numbered according to their capacity, with the most common sizes ranging from 0.13 ml (size 5) to 1.37 ml (size 000) in approximately eight size increments.

Q: Are Gelatin Hard Capsules safe and non-allergenic?

A: Gelatin is a foodstuff and not an additive. The gelatin in capsules is non-allergenic and safe for consumption. It is a pure protein, easily digestible and free from side effects.

Q: What is the difference between Hard Gelatin Capsules and tablets or pills?

A: Tablets are compressed powders, while pill is a generic term for solid oral dosage forms of medicines or food supplements. In gelatin hard capsules, the active ingredients are inside the shell and are thus encapsulated and protected. Thanks to the smoother surface compared to tablets, capsules are also easier to swallow and are therefore more popular with many consumers.
