Ningbo Nexa Machine Co., Ltd. stands as a premier global manufacturer and pioneer in food and pharmaceutical packaging technology. Specializing in the design, engineering, and manufacturing of sophisticated form-fill-seal lines, we cater to high-output industrial demands with custom automation solutions. Our core focus centers on developing reliable vertical stick pack lines, multilane high-speed dosing systems, and secondary cartoning units that streamline production from raw material feeding to secondary packaging.
By constantly integrating state-of-the-art servo-drive technologies, micro-metric filling controls, and intelligent diagnostic features, we enable processing enterprises to achieve ultra-precise fill weights, eliminate downtime, and significantly reduce material waste. Our commitment to strict manufacturing standards ensures that every system built satisfies CE, GMP, and ISO guidelines, giving global operators absolute operational confidence.
Modern lifestyle developments drive consumer preference toward portable, pre-dosed, single-serve formats. Stick packs provide the ideal balance of convenience, cleanliness, and exact portion size, showing double-digit volume growth annually across energy drinks, instant tea, and liquid pharmaceuticals.
Modern plants are migrating rapidly away from multi-layered non-recyclable laminates toward mono-materials, paper-based barrier pouches, and compostable films. We optimize heat-sealing dynamics to process these heat-sensitive eco-films with zero compromise on gas-barrier integrity.
Stricter compliance criteria demand that stick pack machinery isolates dosing components, handles hazardous powders with dust extraction systems, integrates batch printing/laser engraving, and ensures total conformity with FDA, cGMP, and European Hygienic Design standards.
Nexa's stick pack equipment relies on mechanical simplicity backed by deep electronic automation. Each lane operates as a synchronized sub-system, delivering uniform film tensioning, precision dosing, hermetic sealing, and high-speed cutting.
Handling hygroscopic or statics-laden powders (collagen, sports electrolytes, powdered probiotics) requires airtight containment. Nexa integrates nitrogen injection modules, dust hood collectors, and custom vibration hoppers to guarantee consistent powder densities and stable shelf lives.
Products like functional honey, pharmaceutical syrups, and energy gels require drip-free, high-precision liquid pumps. Our rotary lobe or rotary valves feature clean cut-off suck-back nozzles, preventing any product contamination in the seal area.
By connecting multi-lane packaging units directly to our vertical side-loading cartoning systems, the process achieves fully automated multi-count product packing, eliminating manual product handoff costs.
For high-capacity global packaging plants, equipment safety and compliance certificates are not optional. Ningbo Nexa Machine Co., Ltd. design platforms undergo strict regulatory verification processes. All contact surfaces are fabricated using FDA-approved SUS316L stainless steel, utilizing polished mirror-finishes to avoid powder adhesion and minimize bacteria cultivation risk.
We supply complete documentation packages to assist pharmaceutical and dietary supplement operators, including detailed FAT/SAT procedures, IQ (Installation Qualification), OQ (Operational Qualification), and assistance with PQ (Performance Qualification) steps. Our automation interfaces fully comply with safety standards, featuring interlocked guards, low-voltage control setups, and reliable E-stop circuits.
Through our network of regional partners and remote diagnostics capabilities, Nexa ensures rapid response troubleshooting, PLC updates, and high-turnaround parts delivery for European and American markets.
Our upcoming generation of stick pack systems will integrate machine learning feedback loops. Real-time infrared thermal cameras will read temperature consistency across the film seam, adjusting heater energy parameters on the fly without mechanical intervention.
To support next-generation bio-materials that cannot withstand thermal exposure, Nexa is developing reliable cold-sealing and advanced ultrasonic fusion heads, drastically reducing energy footprint and expanding processing capabilities.
Moving toward zero-unscheduled downtime, our machinery uses IoT sensors to track vibration, temperature anomalies, and motor torques. Operators receive preventative warning alerts before mechanical components fail.










Our systems are fully compatible with complex laminate films (PET/AL/PE, PET/PE, Paper/AL/PE) as well as modern recyclable mono-materials and bio-compostable barrier film sheets. The PID-controlled sealing systems ensure high seals even on heat-sensitive materials.
We utilize high-speed servo-driven augers or volumetric cups combined with vibration feeding hoppers. These components maintain an even material column height and pressure, ensuring weight accuracy variances remain well below +/-1% for food and medical grades.
Yes. Due to our modular construction, the raw material dosing module (e.g., auger elevator or liquid piston pump) can be swapped out. This enables a single vertical form-fill-seal chassis to handle liquid condiments, dry coffee powders, or granulated sugars after corresponding clean down and changeover.
We supply a complete validation packet which includes technical manual sets, materials certificates, calibration metrics, FAT documentation, and physical checklists to support your IQ/OQ/PQ processes and ensure compliance with strict GMP protocols.
We integrate active ionizing air eliminator bars along the film feeding path to neutralize static charge build-up. Additionally, custom-designed dust manifold ports are linked directly to extraction systems to keep seal lanes clean.
Standard configurations require 45 to 60 days. Fully customized lines featuring multi-lane dosing synchronizations, secondary automated cartoning, and active validation integrations require 75 to 90 days from technical approval of CAD layouts.
