Ningbo Nexa Machine Co., Ltd. is a leading China food packaging machine manufacturer specializing in the design, development, production, and supply of automatic packaging systems and integrated packaging solutions for the global food industry. With years of industry expertise and a commitment to technological innovation, Nexa Machine delivers reliable, efficient, and intelligent packaging equipment to customers worldwide.
Our extensive product portfolio includes vertical form fill seal machines, vacuum packaging machines, pouch packaging systems, tray sealing machines, thermoforming packaging machines, sachet packaging machines, flow wrapping machines, cartoning machines, weighing and filling systems, and fully automated packaging lines. These solutions are widely used in the packaging of snacks, frozen foods, bakery products, confectionery, dairy products, powders, granules, liquids, pet food, and other food applications.
In addition, we offer flexible OEM and ODM services, providing customized packaging solutions tailored to customers' specific production needs. Serving clients across Europe, North America, South America, Southeast Asia, the Middle East, and Africa, Ningbo Nexa Machine Co., Ltd. has established long-term partnerships with food manufacturers, distributors, and industrial integrators worldwide.
As consumer lifestyles tilt toward portability and precise dosing, stick pack packaging has evolved from a novel design choice into a core packaging format across the pharmaceutical, food, cosmetic, and chemical sectors. Today’s industrial landscape demands automated multi-lane stick pack systems that offer not only extreme throughput but also high adaptability to green materials.
The contemporary technical roadmap focuses on transition architectures: shifting from mechanical drive systems to fully synchronized multi-axis servo systems. This allows for real-time adjustments of draw-down lengths, optimization of sealing jaw dwell times, and integration of laser scoring devices. By utilizing high-frequency, non-thermal ultrasonic sealing modules, we minimize thermal stress on the packaging material. This enables food and pharmaceutical enterprises to adopt recyclable, mono-material PE or paper-based barrier films without compromising seal integrity.
Looking forward, the next decade will be defined by intelligent edge computing within the packaging line. Integrated machine vision inspection monitors seal cosmetics and alignment errors on-the-fly, instantly discarding deviations without interrupting the workflow. Additionally, predictive health monitoring tracks servo-motor current fluctuations, signaling mechanical adjustments before component wear leads to unscheduled downtime.
Meeting GMP standards requires absolute dosage consistency. Nexa's multi-lane systems incorporate high-accuracy micro-augers and specialized anti-dusting vacuum closures, maintaining dosage tolerances within ±1% for vitamins, probiotics, and active ingredients.
From instant coffee blends and prebiotic powders to liquid honey and sauce packets. Nitrogen flushing features reduce residual oxygen levels to below 1.5%, dramatically extending shelf life without requiring chemical preservatives.
High-viscosity pistons fill single-dose liquid foundations, hand sanitizers, and specialty adhesives. Anti-drip cutting nozzle geometries guarantee contamination-free sealing surfaces, preventing leakage in distribution channels.
Ningbo Nexa Machine Co., Ltd. harnesses the industrial concentration of Ningbo's world-renowned mechanical manufacturing cluster. Our modern facility operations run on a foundational "Factory 4.0" layout. Through automated vertical machining centers and high-precision laser cutters, we fabricate major structural components in-house to guarantee structural stability, strict tolerance levels, and component longevity.
Our supply chain structure protects international buyers from market volatility. We maintain raw stock allocations of high-grade SUS304 and SUS316L stainless steel alongside components from premium global brands (including Siemens PLC, Omron temperature controls, and Festo pneumatics). This balance of localized heavy machining and standardized control elements shortens delivery times and ensures global parts availability for maintenance teams.
To aid packaging engineers and procurement committees in comparing layout dimensions and machinery capabilities, we have compiled our baseline configurations:
| Parameters | 4-Lane Stick Pack System | 8-Lane Stick Pack System | 12-Lane Stick Pack System |
|---|---|---|---|
| Lanes Configuration | 2 to 4 Lanes | 4 to 8 Lanes | 8 to 12 Lanes |
| Maximum Web Width | 280 mm | 560 mm | 960 mm |
| Stick Pack Width Range | 17 mm to 45 mm | 17 mm to 40 mm | 15 mm to 30 mm |
| Stick Pack Length Range | 50 mm to 180 mm | 50 mm to 180 mm | 50 mm to 160 mm |
| Speed (cycles/min per lane) | 30 to 65 ppm | 35 to 60 ppm | 35 to 55 ppm |
| Filling Mechanism | Volumetric Cup / Auger Filler | Rotary Valve Piston / Auger | Micro-Auger / Liquid Piston |
| Filling Accuracy | ≤ ± 1.5% | ≤ ± 1.0% | ≤ ± 0.8% |
Navigating international market access requires strict adherence to safety and hygiene protocols. All machinery engineered by Ningbo Nexa Machine complies with the European Machinery Directive 2006/42/EC and carries valid CE certifications. For North American sites, we supply electrical components under UL-listed criteria and offer local NEMA-compliant enclosures.
Understanding that our clients operate in heavily audited environments, we offer complete support documentation for site validation, including IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) protocols. Once a system is delivered, our global partner network provides commissioning, operator training, and remote diagnostic services, minimizing start-up times.
Selecting the ideal machinery partner involves assessing long-term operational expenses alongside initial capital expenditure. Procurement managers should evaluate three primary pillars when assessing potential equipment:
1. Film Compatibility and Reel Width Optimization: High-performance lines must maintain consistent film tension across wider reels. Nexa's automatic web alignment system prevents uneven stretching, which can lead to off-center seals and waste.
2. CIP (Clean-In-Place) Capabilities: For liquid food applications, downtime is frequently lost to cleaning cycles. Piston assemblies that feature toolless disassembly or integrated clean-in-place cycles reduce turnaround times between product changes.
3. Overall Equipment Effectiveness (OEE) Metrics: Enterprise buyers should require evidence of a machine's continuous run capability. Our machinery design prioritizes accessible maintenance pathways, reducing mean-time-to-repair (MTTR) and keeping OEE performance above 92%.
Our machines are designed to run standard laminated films, including PET/AL/PE, PET/PE, and Paper/AL/PE. Additionally, we offer custom heat and ultrasonic sealing configurations compatible with eco-friendly alternatives such as recyclable mono-materials and compostable PLA films.
For powders, we use servo-driven micro-augers where each lane is independently controlled. This allows for precise rotational adjustments during operations. We also integrate feedback systems with checkweighers to auto-correct feeding parameters in real-time.
We supply standard validation support, including IQ/OQ templates, component material certificates (specifically for food-contact components), calibration certs for sensors, and full documentation to support your facility's FDA or GMP certification audits.
A standard line takes 60 to 75 days to manufacture. Highly customized setups with auxiliary systems (like cartoning lines or specific dosing systems) typically require 90 to 120 days. This timeline includes rigorous factory acceptance testing (FAT) before shipment.
Quality is built from the ground up. Below is a look inside our manufacturing floor, assembly lines, and testing stations. Here, every system undergoes 72 hours of dry and wet testing under simulated production conditions before final release.
