Empty capsule

Empty capsules from Zhejiang Tianlong Capsule Co., Ltd. are gelatin-based or HPMC-based shells designed for pharmaceutical and nutraceutical encapsulation, available in standard sizes 0#, 1#, 2#, and 3#. Each capsule is machine-formed to precise dimensional tolerances, with length and diameter consistent within ±0.1 mm per batch. The capsules are free from visible defects such as cracks, discoloration, or air bubbles, ensuring reliable sealing performance during filling operations.

The material composition complies with standard pharmacopeial requirements for gelatin (USP/EP) or hydroxypropyl methylcellulose (HPMC) for vegetarian options. Typical moisture content ranges between 10% and 13%, critical for maintaining shell integrity and preventing brittleness or stickiness. Capsules are available in clear, opaque, or colored variants, with custom printing in water-based ink for brand identification. The production environment adheres to GMP conditions, though no formal certification is stated in the listing.

These capsules are purchased by manufacturers of dietary supplements, veterinary medicines, and over-the-counter pharmaceuticals requiring consistent dosing and rapid disintegration. Buyers typically order in bulk, with packaging in HDPE drums or sealed cartons to prevent moisture ingress. Trade terms such as FOB or CIF are available upon request, but MOQ and lead time must be confirmed directly with the supplier.
