Explore our elite engineering series featuring precision filling, hermetic sealing, and customized atmosphere modulation solutions.
In the modern international logistics and agricultural supply chain, Modified Atmosphere Packaging (MAP) has transitioned from an optional preservation technique to an absolute requirement. As leading CE certified manufacturers and exporters, we resolve the central challenge of global food commerce: extending shelf life organically without chemical preservatives or freezing, while maintaining visual, textural, and nutritional perfection.
By integrating advanced gas-flushing systems with robust mechanical design, our machinery creates a hermetically sealed environment with precisely regulated concentrations of Oxygen (O2), Carbon Dioxide (CO2), and Nitrogen (N2). This limits bacterial proliferation and preserves cellular moisture.
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 the food and pharmaceutical supply chain, machinery safety, high sanitary standards, and operating reliability are non-negotiable. The CE Mark on our Modified Atmosphere Packaging systems indicates compliance with European Union directives. For our global buyers, this certification ensures:
Conventional packaging machinery often achieves gas flushing at the expense of sealing integrity or gas concentration accuracy. Our proprietary dual-stage vacuum/gas-exchange method ensures residual oxygen levels are consistently kept below 0.5%. This control arrests oxidative degradation and rancidity in lipid-rich foods, and halts mold spore respiration in bakery products.
Sourcing Modified Atmosphere Packaging systems from Ningbo, China, offers significant cost, lead-time, and engineering advantages:
Situated next to the Port of Ningbo-Zhoushan, we minimize international shipping logistics overhead and shorten delivery schedules.
Proximity to advanced precision toolmakers allows us to prototype custom packaging tooling and sealing molds in days rather than weeks.
By pairing Western control components (like Siemens PLCs, Omron thermoregulators, and SMC pneumatics) with localized structural engineering, we deliver reliable equipment at a lower capital cost.
How Ningbo Nexa Machine Co., Ltd. addresses the preservation demands of various industries.
Every food category requires a distinct gas profile and mechanical handling strategy to ensure long shelf lives and product stability. Our MAP solutions are tailored for three primary sectors:
These proteins require a high-oxygen mixture (typically 70% to 80% O2) combined with Carbon Dioxide (20% to 30% CO2). The elevated O2 level maintains myoglobin oxygenation, keeping beef and pork a bright, appealing red. Meanwhile, the CO2 dissolves into the food's aqueous phase, lowering the pH to inhibit aerobic spoilage bacteria.
Fungal pathogens like mold thrive in aerobic atmospheres. For products like sliced bread, cakes, and filled pastries, our machines purge the oxygen using 100% Nitrogen (N2) or a Nitrogen-Carbon Dioxide blend. This process prevents mold growth without drying out the product, eliminating the need for synthetic preservatives.
These dry products are highly vulnerable to lipid oxidation and pest infestation. A pure Nitrogen purge is applied to create an inert environment inside the bag, which maintains crispness, preserves flavor profiles, and prevents package collapse.
