As a leader in liquid delivery capsules, this product features a fast-digesting formula that ensures rapid release of liquid contents, maximizing nutrient absorption.

Core Advantages

Optimized Digestibility for Liquid Formulas

Engineered for liquid encapsulation, the capsule’s thin, digestible wall breaks down quickly in the digestive system, preventing liquid leakage and ensuring timely absorption of active ingredients – critical for liquid supplements and pharmaceuticals.

100% Pure & BSE-free Composition

Crafted with 100% bone glue (gelatin) or hypromellose (vegetarian), these capsules are BSE-free empty capsules with zero preservatives or additives. The gelatin variant has <40-50ppm heavy metals, while the HPMC version meets stricter <20ppm standards, ensuring safety for sensitive users.

Size 0 Capacity for Versatile Liquid Filling

With a 0.68ml volume, the Size 0 empty capsule supports liquid capacities ranging from 544mg (0.8g/cc) to 816mg (1.2g/cc), accommodating thin serums, viscous herbal extracts, and pharmaceutical suspensions with ease.

Temperature & Humidity Stability

The HPMC variant offers exceptional stability at 10-40℃, resisting brittle breakage (low temp) and softening (high temp), while the gelatin version performs reliably at 10-25℃. Both variants thrive in 35-65% humidity, ensuring shelf stability in diverse environments.

Custom Branding & Labeling

With a wide array of color options (orange-white, dark blue-white, clear-clear, etc.), custom color empty capsules align with brand identities. Flexible printing solutions enable dosage labeling, logo display, or safety instructions, enhancing product professionalism.

High Compatibility & Filling Efficiency

Boasting a high filling rate of 99.9% (gelatin) and >99.9% (HPMC), these capsules integrate seamlessly with automatic liquid filling machines, reducing waste. The secure locking design prevents leakage, even with volatile or viscous liquids.

Inclusive for Diverse Consumers

The HPMC Liquid Capsules are vegetarian-friendly, suitable for vegetarians, vegans, and followers of Judaism/Islam. The gelatin variant caters to mainstream consumers, expanding brand reach across demographics.

Globally Recognized Certifications

Backed by ISO9001, HALAL, and COA certifications, these liquid supplement capsules meet international quality benchmarks, facilitating market entry in North America, Europe, and the Middle East.
