R&D
Qingdao Yilong Packaging Machinery Co.,Ltd. is a pioneer in China’s automated premade pouch packaging industry and a leading drafter of both National and Industrial Standards. As a manufacturer focused on intelligent packaging solutions, we remain market-driven, investing consistently in technical R&D and product optimization. Our team of experienced mechanical, electrical, and automation engineers possesses full-spectrum R&D capabilities—from structural design and control system development to HMI integration.
We have established a modular and serialized equipment platform tailored to diverse material characteristics, including liquids, powders, granules, sauces, multi-component ready meals, and snacks. This allows us to respond rapidly to customized demands in dosing precision, dust/drip prevention, sealing reliability, and pouch compatibility. Our innovations—such as our anti-drip systems for high-viscosity sauces, low-dust dosing for milk powders, and synchronized filling for solid-liquid ready meals—are the result of deep refinement in real-world applications.
Our design philosophy prioritizes stability and usability. Core component selection balances performance with maintenance costs, while our control systems support recipe storage, self-diagnostics, and remote assistance. We actively track global trends in food packaging safety and automation to ensure compliance with international standards.
Looking forward, Yilong remains committed to a pragmatic and innovative approach to provide our customers with reliable, efficient and highly adaptable packaging solutions, thereby supporting the sustainable growth of their businesses.

Located in Chengyang, Qingdao, this primary R&D base handles full-scale mechanical design, electrical control, and prototype testing.
- Team Composition: Senior mechanical engineers, automation experts, and industry consultants (Food, Daily Chemicals, Agrochemicals).
- Technical Focus: Multi-material adaptation (including liquid, powder, granule, sausce, ready meal, etc.), high-precision dosing, intelligent HMI, turnkey line integration, and remote O&M (Operation & Maintenance).
- Deliverables: A serialized rotary premade pouch packaging platform supporting stand-up, zipper, and spout pouches, widely used in supplements, condiments, snacks, and instant noodles.

Yilong’s R&D is driven by practical production requirements. All our packaging equipment are developed, upgraded and revolutionized to carter to customer’s needs, e.g.
- Anti-drip filling systems for liquid healthcare products (Shaped bag packaging machine, liquid pouch packing machine, spouted pouch filling machine, dual-lane pouch packaging machine);
- Dust-free screw weighing and dosing system for milk powder (Powder pouch filling line, on-line weighing and packaging machine, ultra-fine powder packaging machine)
- Customized scraper-type piston pumps for hot pot bases containing solids (Dual-lane rotary pouch packing machine, sauce packaging machine).


Established in 2015, our German R&N center is a cornerstone of our international strategy, focusing on:
- Frontier Technology: Tracking European advancements in smart packaging, energy efficiency, and precision dosing.
- Component Co-development: Partnering with German suppliers for electromechanical, pneumatic, and sensing systems to enhance module reliability.
- International Compliance: Ensuring designs meet CE, GMP, and EHEDG (European Hygienic Engineering & Design Group) requirements.
- Local Technical Support: Providing rapid response for high-end customization projects in Europe, North America, and "Belt and Road" markets.
Through the Germany R&D Center, Yilong has not only introduced advanced engineering concepts and manufacturing standards but also achieved a powerful integration of "Intelligent Manufacturing from China" and "Precision Engineering from Germany." This synergy provides the technical backbone for our automated pouch packaging machines in terms of stability, precision, and intelligence. It also serves as a critical endorsement for our services in industries with stringent hygiene and reliability requirements, such as liquid health supplements, milk powder, ready meals, and condiments.
Currently, our R&D team works in close collaboration with the Qingdao manufacturing base and overseas technical resources to continuously iterate and upgrade our products toward higher precision, stability, and adaptability. Our goal is to provide customers with truly reliable and practical intelligent packaging solutions.
Our pragmatic and experienced team consists of professionals with over 10 years of background in the food and packaging machinery sectors, possessing expertise from different fields such as mechanical design, electrical automation, software control, industrial design and process application.
- Customer-Centric Innovation
We work on-site to solve technical bottlenecks in dosing, filling, and sealing for liquid, solid, powder, granule, sauce, ready meal, leisure snacks, premade pouches. Examples include anti-drip structures for viscous sauces and flexible discharge channels for fragile granules, CE/GMP certified equipment for international clients. - Technical Proficiency
Mastery of SolidWorks/AutoCAD, PLC/HMI development (Siemens, Mitsubishi, Inovance), servo drives, vision recognition, and remote O&M modules. Every new model undergoes rigorous prototype testing and real-material verification to ensure efficiency and reliability.
Yilong’s commitment to independent innovation has yielded competitive market results:
