Capsule Manufacturing

As a soft gel capsule manufacturer, we handle oil-based and liquid-fill formulations — commonly used for Omega-3s, Vitamin E, and other lipid-soluble actives where a hard shell format isn't suitable. The process is built to hold uniform fill volume, shell integrity, and stability across the product's shelf life.

Our hard gelatin capsule manufacturing line supports powder-fill and pellet-fill formulations across therapeutic and nutraceutical categories, with tight control on capsule locking, weight variation, and disintegration performance.

Capsule shell size is selected based on fill volume and dose — from size '000' (largest, ~1000mg fill capacity) down to size '5' (smallest, ~60mg). Our formulation team helps brands select the right capsule size chart position for their active ingredient load during the R&D stage, balancing swallowability with dosing accuracy.

Brands evaluating dosage forms often ask about the difference between tablet and capsule for a new product launch. Capsules offer faster disintegration, easier masking of unpleasant taste or odor, and better suitability for oil-based actives — while tablets typically offer lower per-unit cost at scale and longer shelf stability for moisture-sensitive APIs.

Within capsules, the difference between hard and soft gelatin capsules comes down to shell composition and fill type: hard gelatin capsules are a two-piece shell filled with dry powder or pellets, while soft gelatin capsules are a one-piece, sealed shell formed around a liquid or semi-solid fill. So what are capsules made of? Both shell types are primarily built from gelatin (or a vegetarian HPMC/pullulan alternative), plasticizers, and water — the specific formulation determines shell flexibility and dissolution speed. Understanding how capsules are made at each stage helps brands choose the right format before committing to a production run.
