Ningbo Nexa Machine Co., Ltd. presents its primary selection of thermoforming and high-speed vacuum sealing systems custom-configured for industrial applications in the Vietnamese agricultural, meat, and pharmaceutical sectors.
Optimized for medium-capacity shaping and sealing. Perfect for processing local grains, beans, and compact food packs in Southern Vietnam.
Flexible chamber design supports modified atmosphere packaging (MAP). Ideal for meat processors supplying urban retail networks.
Engineered for medical cleanrooms. Form-fill-seal system for syringes, ampoules, and medical instruments.
Continuous roll-stock design ensuring airtight seals, clean cutting, and extended shelf life for dairy products.
The manufacturing landscapes in industrial zones across Vietnam—spanning from Binh Duong, Dong Nai, and Long An in the South to Bac Ninh, Hai Phong, and Hung Yen in the North—are undergoing a massive paradigm shift. Driven by free trade agreements such as the EVFTA (EU-Vietnam Free Trade Agreement) and CPTPP, local food, agricultural, and medical device exporters are scaling up their infrastructure. High-speed, automated packaging systems are no longer luxury acquisitions; they are essential compliance baselines.
Conventional pre-made vacuum bags limit throughput and incur high manual assembly labor costs. Roll-stock thermoforming packaging machines operate by feeding flat lower plastic film into a forming station, heating and shaping it to match custom-machined cavities, loading products automatically or manually, evacuating air (or injecting protective gas mixtures), sealing with a top web film, and cutting into finished packages. This continuous automation yields consistent retail pack presentation, optimized material consumption, and eliminates manual pouch-opening contamination risks.
Different industrial sectors demand custom-engineered engineering properties from their thermoformer suppliers. Ningbo Nexa Machine Co., Ltd. configures specialized thermoforming machine parameters for target markets:
Seafood processors exporting frozen shrimp, pangasius fillets, and squid require heavy-duty, corrosion-resistant machines. Our thermoformers utilize SUS304 food-grade stainless steel structure, IP69K-rated washdown electronics, and specialized moisture separators to ensure machine reliability in high-salinity, wet production plants.
Vietnam's cashew nut exporters, dried jackfruit producers, and agricultural logistics centers require modified atmosphere systems to retain flavor, block ambient humidity, and stop bug infestation. Integrated nitrogen gas flushing options help keep oxygen levels below 0.5% inside the finished pack.
Packaging syringes, medical IV sets, and high-precision electronic modules calls for dust-free, cleanroom-certified forming processes. Rigid ABS and PET blister trays protect sensitive products during transport, complying with cleanroom particulate standards.
Ningbo Nexa Machine Co., Ltd. builds thermoforming equipment incorporating advanced components designed to lower total cost of ownership (TCO) and maximize equipment uptime in tropical processing environments.
Vietnam's high ambient relative humidity (often exceeding 85%) presents corrosion issues for electronics and steel supports. Nexa machines feature sealed electrical cabinets with dynamic cooling fans (or optional active heat exchangers), ensuring internal moisture does not condense. All frame members are constructed from structural stainless steel, avoiding carbon steel exposure.
Our thermoformers employ optical film registration sensors and Siemens/Omron servo-driven chain advance mechanisms. This permits the handling of printed top-web films (for brand designs) and keeps registration within ±0.5 mm tolerances. Combined with optimized rotary knife systems, scrap edges are minimized, saving film costs.
Different thermoforming materials (such as APET, PVC, PP, and eco-friendly PLA) require narrow temperature forming windows. Nexa machines use PLC-integrated PID controllers with multi-zone plate heaters, guaranteeing temperature uniformity across the forming tool within ±1°C.

Q1: Which plastic films are best suited for thermoforming machines in Vietnam's tropical climate?
A1: For standard vacuum applications, flexible films like PA/PE (Polyamide/Polyethylene) co-extrusions are typically used. For high-barrier configurations (such as MAP or long shelf-life retail products), films containing EVOH are recommended. If packaging rigid trays, APET or PP films are chosen. In Vietnam's humid conditions, using top-quality film with proper anti-fog additives helps avoid internal moisture condensation, maintaining excellent product presentation.
Q2: How does Nexa ensure machine durability in wet and salty seafood packaging environments?
A2: All Nexa seafood packaging thermoformers are built using heavy-gauge SUS304 stainless steel. Electrical cabinets are IP65 or IP69K rated. They feature double-sealed doors and internal cooling vents designed to exclude washdown water. Dynamic mechanical components are constructed from anti-corrosive materials, and pneumatic lines are routed internally where possible to prevent exposure to corrosive spray.
Q3: What is the typical lead time and installation schedule for deliveries to Vietnam?
A3: Manufacturing lead times range from 45 to 60 days, depending on mold complexity. Shipping from Ningbo Port to Haiphong or Ho Chi Minh City ports takes 5 to 10 days. Once the machine arrives at your factory, Nexa engineers can be dispatched to oversee physical placement, hook up utility connections (power, compressed air, cooling water), and train operators within 5 to 7 days.
Q4: Can Nexa machines handle variable power supplies in different industrial parks?
A4: Yes, we build all control cabinets to match your facility's power specs. The standard configuration for industrial installations in Vietnam is 380V, 50Hz, 3-Phase. We integrate high-quality electrical components (Siemens, Schneider, or Omron) that handle voltage fluctuations within standard tolerances, safeguarding your PLC and motor drives.
Q5: How easy is it to change molds for different product sizes on a Nexa thermoformer?
A5: Our thermoformers are designed with rapid-change mold mechanics. An experienced operator can swap forming plates, sealing plates, and cross-cut knives within 30 to 45 minutes. The PLC system allows storing multiple recipes, so you can call up pre-saved heating times, vacuum depth parameters, and gas values instantly.
Q6: What maintenance steps are recommended to ensure long-term vacuum pump efficiency?
A6: Weekly checks of pump oil levels and oil clarity are essential, especially when processing wet products. Oil filters and exhaust filters should be replaced every 500 to 1000 operating hours. Using high-quality vacuum oil prevents moisture emulsification, keeping your vacuum system performing at peak capacity.
