Capsules are everywhere—from dietary supplements to prescription medications. But have you ever wondered what they're made of or how they’re produced? In this guide, we’ll break it down for you in a simple, easy-to-follow way, covering everything from materials to the manufacturing process and beyond.

Capsules are typically made from gelatin (derived from animal collagen) or plant-based alternatives like HPMC (hypromellose). The manufacturing process involves creating capsule shells, filling them with medication or supplements, and sealing them to ensure quality and safety.

What Are Capsules Made Of?

Capsules are made from two primary materials:

Gelatin Capsules

1. Made from animal collagen (commonly derived from bovine or porcine sources).

2. Cost-effective and dissolves quickly in the stomach.

3. Popular for pharmaceuticals and supplements.

Vegetarian Capsules

1. Made from plant-based materials like hypromellose (HPMC) or pullulan (fermented from tapioca).

2. Ideal for vegetarians, vegans, and people with dietary restrictions.

3. Moisture-resistant and suitable for sensitive contents.

How Are Capsules Manufactured?

The capsule-making process is fascinating! Here’s how it works step by step:

Preparing the Materials
Gelatin or HPMC is dissolved in water to create a gel-like mixture. Additional ingredients like colorants or preservatives can be added at this stage.

Forming the Capsule Shells

1. Steel pin molds are dipped into the gel to create capsule halves (the body and cap).

2. These halves are dried, trimmed, and inspected.

Filling the Capsules

1. The empty capsule body is filled with powders, granules, or liquids using automated machines.

2. Precise filling ensures the correct dosage in every capsule.

Sealing and Polishing

1. The capsule cap is placed on the body and sealed to prevent leaks.

2. Capsules are then polished for a smooth, professional finish.

Quality Inspection and Packaging

1. Capsules undergo rigorous checks to ensure they meet weight, appearance, and safety standards.

2. Finally, they’re packed into blister packs, bottles, or other containers.

How Should Capsules Be Stored?

Storage is key to maintaining capsule quality. Here's how to do it right:

· Keep it cool: Store capsules at 15–25°C.

· Avoid moisture: Humidity should be between 35–65%.

· No direct sunlight: UV rays can degrade capsules.

· Seal tightly: Prevent exposure to air or contaminants.

What About Capsule-Making Machines?

Capsule machines are essential for efficient production. Here’s what to know:

· They vary in size, from small manual machines for personal use to large-scale automated systems for factories.

· Automated capsule fillers ensure precise dosage and high-speed production.

· Top manufacturers like LTPM CHINA offer customizable capsule machines to meet diverse production needs.

What’s the Difference Between Capsules and Pills?

Capsules and pills might seem similar, but they have key differences:

· Capsules dissolve faster and are easier to swallow.

· Pills (tablets) are compact and have a longer shelf life but may dissolve slower.
