Explore our flagship lineup of industrial-grade sealing, wrapping, and container handling systems engineered for high-throughput operational excellence.
In the modern commercial food manufacturing sector, sealing machines represent the critical barrier between production integrity and environmental degradation. The global packaging landscape demands ultra-reliable hermetic sealing parameters to prevent product cross-contamination, deter premature spoilage, and adhere to strict sanitation guidelines set forth by agencies like the FDA, EHEDG, and European Union Food Directives.
As contract food packagers (Co-packers) and global food exporters scale up their production capacities, manual processes are quickly transitioning to high-efficiency continuous, rotational, and form-fill-seal automation systems. Henan Collins Machine Co., Ltd. fills this industrial need by providing robust machinery capable of handling varying film gauges, multi-layer composite structures, and biodegradable barrier papers.
Whether processing fresh proteins using modified atmosphere technology or running high-speed vertical liquid sachet packaging, our machines maintain exact temperature stability and pressure configuration profiles, guaranteeing less than 0.1% leak-defect margins in large-scale run cycles.
Leveraging intelligence, efficiency, and sustainability to deliver the next generation of automated packaging machinery.
Our upcoming generation of high-speed sealing machines integrates sensor suites that trace heat-bar performance, pneumatic pressure, and cycling time in real-time. By sending data directly to factory ERPs via MQTT protocols, operators can predict component wear and pre-emptively schedule repairs, preventing unplanned line shutdowns.
To support temperature-sensitive products such as dairy, chocolate bars, and fresh frozen foods, Collins is advancing its ultrasonic sealing systems. Ultrasonic activation generates localized micro-frictional heat only inside the film's polymer boundaries, preserving product shape and keeping cooling costs minimal.
By employing ultra-precise Omron PID loops, Collins sealing units achieve rapid thermal recovery rates. This technology guarantees thermal stabilization within ±1°C, even during sudden cycle speed surges from 30 to 120 bags per minute, preventing under-sealed or burned edges.
Walk through our structured fabrication steps, designed to maintain strict quality standards from raw metal sheets to final tested machinery.
Food sealing requirements depend heavily on regional regulatory frameworks and local product preferences. Henan Collins optimizes and configures systems to match these conditions. Our localized scenarios cover diverse packaging styles, including retort pouch processing, modified atmosphere packaging (MAP), and vacuum skin pack (VSP) systems.
For example, in North America and Western Europe, where there is a strong focus on shelf life and chemical-free preservation, we configure our multi-station rotary vacuum machines with gas purging modules. This injects nitrogen gas to displace residual oxygen before heat-sealing, which protects nuts, dried fruits, and pet food from oxidation.
Conversely, for clients in tropical areas such as Southeast Asia or West Africa, where high relative humidity can degrade machine components, we upgrade key structural elements to electropolished SUS316L. We also build hermetically sealed NEMA 4X / IP66 control cabinets to protect delicate electronic systems from humidity and dust.
Our OEM/ODM workflow is structured to deliver dependable performance for custom packaging configurations. We start with film-compatibility trials and product density analysis to guide engineering layouts. From there, we design custom seal jaw profiles and define heat recovery steps.
Once design prototypes are finalized using 3D modeling, we program custom PLC presets and establish the machine frame structure. Every finished system undergoes a continuous 72-hour test run under full-load conditions using customer-provided packaging materials. This thorough testing guarantees that every machine arriving at a client's facility is fully optimized for immediate integration.
Henan Collins Machine Co., Ltd. operates from Henan Province, a central industrial hub in China. This location connects our operations to major steel plants, CNC component fabricators, and raw material suppliers. Our localized supply ecosystem reduces raw material transit times and minimizes overhead costs compared to coastal manufacturing sites.
Through our established supplier network, we can secure certified electrical components, precision servos, and high-tensile casting alloys without long procurement delays. This structured supply chain allows us to maintain stable lead times, even when global logistics are disrupted, ensuring consistent equipment delivery schedules.
We combine this supply network with lean manufacturing methods. Every phase of production—including CNC milling, precision welding, and final assembly—is kept in-house. This centralized approach reduces third-party dependencies, keeps pricing competitive, and ensures complete control over final quality.
Additionally, our proximity to the Zhengzhou International Logistics Hub provides reliable shipping connections to major export routes. We utilize direct high-speed freight rail to Europe and container shipping through major ports like Qingdao and Shanghai, offering flexible and cost-effective shipping options to global markets.
By coordinating our engineering, component sourcing, and export shipping, we offer international buyers a reliable supply path. This reliable workflow minimizes the delays and hidden transaction costs often found when dealing with fragmented supplier networks.
Our manufacturing processes are ISO 9001 certified, and all export-grade machines carry official CE marking, SGS verification reports, and RoHS compliance certificates, simplifying local regulatory approvals.
We provide remote video configuration guides and direct support lines staffed by experienced English, Spanish, and Russian-speaking support engineers to resolve technical issues quickly.
We maintain an inventory of standard wear items—such as Teflon tapes, heating elements, pneumatic cylinders, and cutting blades—ready for dispatch within 24 to 48 hours to minimize downtime.
For dusty filling operations (such as ground coffee, cocoa, starch, or spice packaging), we integrate dynamic bag-mouth dust-cleaning air jets. Additionally, we use customized grooved seal jaws that exert concentrated, high-pressure profiles. This ensures that any residual powder is pushed out of the sealing area, producing clean, hermetic seals without leakage.
Operators have precise control over sealing temperature limits, heat contact times, bag length dimensions, film feed speeds, conveyor feed intervals, and air extraction volumes. The touch-screen HMI supports multi-recipe storage, allowing operators to switch between different bag materials and sizes with a single preset selection.
Our machinery is designed to seal a broad range of films, including single-layer LDPE/PP, heavy-gauge multi-layer laminates, nylon co-extrusions, metalized foils (PET/AL/PE), and newer biodegradable and compostable paper structures. Temperature profiles can be configured on the PLC interface to match the exact melting point of each material.
Standard, non-customized equipment is typically shipped within 15 to 20 business days. For customized OEM/ODM projects requiring custom PLC integration, specialized tooling, or specific stainless steel grades, the build time ranges from 30 to 45 business days. This timeframe includes our mandatory 72-hour continuous test run.
