The Future is Liquid: Why Leading Brands are Switching to Liquid-Filled Capsules
Discover the three core advantages that are making liquid-filled hard capsules the preferred delivery system for high-value supplements and pharmaceuticals.
Enhanced Bioavailability
Liquid and semi-solid formulations can improve the absorption and efficacy of active ingredients like CBD, fish oil, and fat-soluble vitamins, delivering faster, more predictable results for consumers.
Formulation Flexibility
Perfectly encapsulate oils, pastes, and suspensions that are impossible to formulate as powders. Ideal for overcoming challenges with low-melt-point substances and complex active ingredients.
Superior Product Appeal
Offer a premium product with better taste-masking and improved shelf stability. The crystal-clear, leak-proof finish creates a high-end look that commands consumer trust and a higher price point.
Our 3-Step Process for Perfect, Leak-Proof Liquid Capsules
From precision injection to hermetic sealing, every stage is meticulously engineered to ensure the integrity and quality of your final product.
Precision Liquid Injection
Our servo-driven pump, connected to a heated and stirred tank, injects a precise dose (±3% accuracy) of your liquid formulation into the capsule body. It perfectly handles everything from low-viscosity oils to thick pastes.
Intelligent Capsule Closing & Rejection
Filled capsules are securely closed. Our photoelectric detection system then inspects each capsule, automatically rejecting any that are unclosed or flawed before they can reach the critical sealing stage.
Secure Band Sealing
This is the most critical step. A gelatin band is applied to the cap-body interface and dried, creating a robust, tamper-evident, and hermetic seal.
This is how we guarantee a leak-proof result. It's the final lock on quality.
Not Just a Machine, But a Complete Oil Capsule Filling Solution
Every component of the NJP-260L is engineered to solve the unique challenges of liquid encapsulation—from maintaining formulation consistency to ensuring absolute leak-proof sealing.
Heated & Agitated Filling Tank
Maintains your formulation at the optimal temperature and consistency, ensuring uniform filling from the first capsule to the last. Perfect for semi-solids and suspensions that require precise thermal management.
High-Precision Servo Pump System
Provides unparalleled dosing accuracy and repeatability. Easily adjust fill volume via the touchscreen, minimizing product waste and ensuring dose consistency across every batch. Works flawlessly with low-viscosity oils to thick pastes.
Intuitive PLC & Touchscreen Control
Simplifies operation and parameter setting. Store recipes for different formulations, manage production data, and meet 21 CFR Part 11 requirements with built-in user management and audit trails. Reduce training time and eliminate operator errors.
Robust cGMP Construction

Your Questions on Liquid Capsule Filling and Sealing, Answered
We've answered the most critical technical questions from our clients. Don't see your question? Contact our team for personalized guidance.
What is the viscosity range the machine can handle?
The HIJ NJP-260L is designed to handle a wide viscosity spectrum, from low-viscosity oils to thick pastes and suspensions. Our servo-driven dosing pump and heated filling tank system ensure precise and consistent filling across different formulation types.
Low Viscosity: 1-100 cP (e.g., MCT oil, vitamin E)
Medium Viscosity: 100-1,000 cP (e.g., CBD oil, fish oil)
High Viscosity: 1,000-5,000 cP (e.g., herbal pastes)
Temperature Control: Heated tank up to 80°C
Key Feature: Our filling tank includes a built-in heating and stirring system, which maintains your formulation at the optimal temperature and prevents sedimentation during production. This is critical for suspensions and high-viscosity liquids.
Test Your Formulation for FreeHow does the sealing process work and how strong is the seal?
Sealing is the most critical step in liquid capsule production. The HIJ NJP-260L uses Gelatin Band Sealing Technology, which is the industry-standard method for creating a leak-proof, tamper-evident seal.
How It Works:
- After the capsule body is filled with liquid, the cap is precisely placed onto the body.
- A thin band of warm gelatin solution (same material as the capsule shell) is applied to the cap-body junction.
- The gelatin band is then dried using a controlled airflow system, forming a permanent molecular bond with the capsule shell.
- This creates a hermetic, tamper-evident seal that prevents leakage and oxidation.
Seal Strength: Our sealed capsules pass rigorous quality tests, including vacuum leak testing, tumble testing, and dissolution testing, ensuring zero leakage during storage, transportation, and shelf life.
Request Seal Test VideoCan I use the same machine for liquids and powders?
Short Answer: No, the NJP-260L is a dedicated liquid capsule filling and sealing machine. It cannot be used for powder filling.
Why? Liquid and powder capsules require fundamentally different technologies:
- Liquid Machines use servo pumps, heated tanks, and gelatin band sealing systems.
- Powder Machines use dosing discs, auger fillers, and do not require sealing (the cap is simply locked onto the body).
Investment Consideration: While they are separate machines, many of our clients operate both. The ROI for liquid capsules is typically higher due to:
- Higher product value (CBD oils, Omega-3, fat-soluble vitamins)
- Better bioavailability and consumer appeal
- Ability to formulate products that cannot be made into powders
If you need both capabilities, we can design a dual-line solution for your facility.
Discuss Your Production NeedsWhat is the cleaning and changeover time?
We understand that downtime is lost revenue. That's why the NJP-260L is designed with a tool-free disassembly system and a streamlined cleaning protocol.
Quick Rinse: 15-20 minutes (for color/flavor change)
Deep Clean: 45-60 minutes (for API or allergen change)
No Tools Required: Hand-tightened clamps only
CIP-Ready: Optional Clean-in-Place system available
Key Design Features:
- All product-contact parts are made of SS316L stainless steel with electropolished surfaces (Ra ≤ 0.4 μm).
- The filling tank and pump assembly can be detached in under 5 minutes without tools.
- No hidden corners or dead spots—every surface is accessible and cleanable.
- We provide detailed cleaning SOPs and validation protocols for cGMP compliance.
Optional Upgrade: For clients with frequent product changes, we offer a portable filling tank system—simply swap out pre-filled tanks for near-instant changeover.
Download Cleaning Validation GuideDo you have experience with filling CBD oil?
Absolutely. CBD oil encapsulation is one of our specialty applications. We've worked with clients in North America, Europe, and Asia to develop robust processes for both full-spectrum and isolate-based CBD formulations.
Why CBD Oil is Challenging:
- Viscosity Variations: CBD oils can range from thin (in MCT carrier) to thick (in coconut oil or with added terpenes).
- Temperature Sensitivity: Cannabinoids can degrade at high temperatures, requiring precise thermal control.
- Oxidation Risks: CBD oxidizes when exposed to air, making a hermetic seal critical.
- Dosing Accuracy: With high-value ingredients, even small dosing variations can significantly impact cost and efficacy.
How We Solve These Challenges:
- Our heated filling tank maintains your oil at the optimal temperature (typically 40-50°C) without degrading cannabinoids.
- The servo pump delivers ±3% dosing accuracy, ensuring consistent CBD content in every capsule.
- Our gelatin band sealing creates an oxygen barrier, preserving product potency throughout its shelf life.
- We provide inert gas purging options (nitrogen or argon) for ultra-sensitive formulations.
Compliance Support: We understand the evolving regulatory landscape for CBD. Our machines are designed to meet FDA 21 CFR Part 111 (dietary supplement cGMP) and EU Novel Food standards. We provide all necessary documentation for regulatory submissions.
