Explore our advanced vertical form fill seal, tray sealing, skin packaging, and recycling solutions engineered for high performance and stability.
Industrial Food Packaging Systems & Global Integration Leadership
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. Driven by years of sector experience, we assist enterprises in streamlining their output pipelines.
Our extensive product line 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/filling systems, and fully automated packaging lines.
Every system undergoes rigorous testing protocols to verify reliability, durability, and processing safety. We leverage flexible OEM and ODM services to deliver custom machinery suited to specific floor configurations, production speeds, and environmental requirements across Europe, the Americas, and APAC.
Understanding B2B market dynamics and processing challenges in modern food distribution systems.
Global food logistics depend on MAP to preserve structural integrity, color, and nutritional value. Displacing ambient oxygen with custom food-grade gas mixtures (CO₂, N₂, O₂) inhibits microbial proliferation, extending product shelf life without relying on chemical preservatives.
VSP contours a flexible top film over products without distorting their texture or shape, fixing the product firmly to the tray to prevent liquid migration. This visual presentation enhances product appeal in retail settings and secures protein products against freezer burn.
Environmental policies drive the adoption of recyclable paperboard, bio-plastics, and thin monomaterial films. Our sealing heads use advanced heat control algorithms to consistently seal heat-sensitive green plastics, helping brands meet their sustainability goals.
Tailored packaging technologies engineered to meet the strict operating guidelines of diverse market sectors.
Automated multi-compartment tray sealing lines with integrated MAP help ready-meal manufacturers protect complex food profiles, prevent flavor migration, and transition smoothly from cold distribution chains to microwave heating.
Constructed with IP65-rated or higher stainless steel chassis, our protein packaging lines handle intensive washdown cycles. By incorporating high-vacuum VSP, these systems prevent oxidation and discoloration in fresh beef, poultry, and seafood.
Using micro-perforated breathable films and precise gas-flushing systems, our produce packers slow down product respiration. This preserves crisp textures and prevents condensation build-up inside the trays.
Developing next-generation smart control, precision heat distribution, and durable tooling designs.
Independent heat-loop sensors maintain uniform heat levels across the sealing plate. This prevents cold spots and over-melt zones, ensuring leak-free hermetic seals even with variable film thicknesses.
Multi-axis servo systems coordinate film tensioning, tray feed, and tool actuation. This eliminates mechanical shocks, reduces vibration wear, and ensures high accuracy during fast production runs.
Our rapid-swap tooling allows operators to change tray formats in minutes. The built-in locating pins self-align, reducing downtime during product changeovers.
A tour of our production facility, assembly floors, and precision CNC milling departments.
Aligning production with regional standards and providing reliable remote and on-site engineering services.
All Nexa machinery complies with CE directives for electronics and machinery safety. Critical system options are available with UL and CSA-certified components, and we use food-contact-approved materials for all parts that touch product lines.
We perform Factory Acceptance Testing (FAT) with your sample trays and materials before shipment. We also support on-site Site Acceptance Testing (SAT) and commissioning to help you quickly ramp up production.
With optional IoT telemetry modules, our engineers can remotely troubleshoot PLC settings, update software, and analyze cycle times, resolving technical issues without waiting for site visits.
Expert answers to common engineering, operational, and maintenance questions.
By using multi-stage gas flushing and high-vacuum evacuation systems, our machines consistently reduce residual oxygen levels to below 0.5% to 1.0%. The exact rate depends on the film structure, product density, and packaging speed.
With our quick-release design, a format changeover takes approximately 10 to 15 minutes. This tool-free process includes changing the upper sealing plate, lower tray nests, and film cutting blade assemblies.
Yes. Our controllers feature precise digital heat profiles and adjustable sealing pressure ramps. This allows the system to run eco-friendly alternatives, like PLA, paperboard, and monomaterials, without burning or failing to seal.
Most of our industrial-grade, continuous tray sealers run on a three-phase 380V/415V, 50Hz/60Hz electrical supply. They require clean, dry compressed air at 0.6 to 0.8 MPa, along with a constant cooling water supply for the sealing frame.
Every shipment includes detailed user manuals, electrical schematics, and recommended spare parts lists. We also offer on-site technician training, video assistance, and priority global shipping on critical components like heating elements, gaskets, and thermocouples.
Standard machines are generally built and tested within 30 to 45 days. Customized projects, including integrated multi-head weighers, automated tray denesters, custom mold shapes, or specific CIP washing setups, typically take 60 to 75 days.
From fine powder filling to structural foam granulating, these systems help you build a complete, high-capacity production line.
