Shanghai Huapack possesses industry-leading full industrial chain integration capability, covering every stage from front-end material feeding, weighing & dosing, horizontal packaging, metal detection, cartoning/bagging, to back-end case packing, case sealing, and palletizing. We deliver true one-stop solutions "from raw material to finished pallet."

Customers no longer need to coordinate with 7-8 different suppliers, nor worry about interface mismatches, incompatible communication protocols, or finger-pointing after-sales service. As a single responsible entity, Huapack handles the entire project lifecycle:
Choosing Huapack's turnkey line integration reduces project management risks by 80% and saves valuable coordination time and costs.
Huapack exports to over 80 countries and regions across North America, Central/South America, Western Europe, Eastern Europe, Oceania, Asia, the Middle East, and Africa. With a strong reputation, high-quality service, and extensive product range, we have earned widespread trust from global customers.
Huapack continues to achieve breakthroughs in four strategic areas: weighing & dosing technology, horizontal packaging technology, one-click intelligent jaw adjustment, and back-end line integration technology. Our five parallel innovation pillars have earned us prestigious qualifications including "Shanghai Innovative Enterprise" and "Shanghai Specialized & Sophisticated Enterprise."
In the packaging machinery industry, powder weighing has long faced the fundamental dilemma that "speed and accuracy cannot be achieved simultaneously." Traditional single-head weighing devices struggle to maintain stable dosing accuracy at high speeds due to uneven powder flow, density fluctuations, and dust generation.
Utility Model Patent – Large & Small Powder Head In-line Weighing System (Granted 2020)
This revolutionary patented technology integrates a large-diameter coarse-feed powder head and a small-diameter fine-adjustment powder head into a single in-line weighing system:
Under real-time feedback from the in-line weighing sensor, the two powder heads work in perfect harmony, dynamically switching within the same control cycle. This fundamentally solves the traditional "speed vs. accuracy" conflict and breaks the long-standing dependence on imported dosing modules in high-precision powder weighing. This technology provides a solid technical foundation for customers requiring pharmaceutical GMP certification and FSMP compliance.
To address industry-wide problems of dust generation, moisture absorption, and strict cleanliness requirements, Huapack has innovatively designed an integrated dust extraction system that effectively collects dust at filling and tamping stations. This system:
Our new-generation fully automatic powder packaging line automates the entire process from dosing, bag making, filling, sealing to coding. After implementation, one customer reported that their production line was simplified from needing 3-4 operators to just one supervisor, with a 40% reduction in waste rate.
Huapack is a leading player in the domestic horizontal fully automatic packaging machinery field, with years of production experience in horizontal automatic packaging machines using four different drive methods.
Unmatched Bag Type Compatibility
Huapack's horizontal packaging machines support all mainstream bag types: 3-side seal, 4-side seal, stand-up pouches, zipper pouches, shaped pouches, spout pouches, 8-side seal bags, and back seal bags. This versatility allows us to meet diverse packaging needs across food, pharmaceuticals, daily chemicals, and health & nutrition industries.
In 2025, Huapack launched its revolutionary "Horizontal Automatic Adjustment Packaging Machine" technology. The core highlight is the industry-leading "one-click adjustment" intelligent function:

This innovation dramatically simplifies the traditional manual method that relied on skilled technicians' "experience and feel" and could take hours of adjustment. Even new employees can become proficient after 30 minutes of training, greatly reducing labor costs and operational barriers.
Huapack prominently featured this breakthrough technology at the PROPAK Shanghai International Exhibition in June 2025 and the swop Packaging World Expo 10th Anniversary Celebration in November 2025, attracting widespread attention from industry leaders in the health & nutrition and beverage sectors.
Huapack's fully automatic packaging machines are equipped with advanced PLC control systems and intelligent HMI touchscreen interfaces. Through built-in AI algorithms, the system automatically adjusts key parameters such as packaging speed and sealing temperature based on real-time conditions, enabling fully automated, digital closed-loop management.
