Engineered to deliver high sealing integrity, precise gas flush ratios, and seamless line integration.
The modern packaging landscape is undergoing a massive shift towards shelf-life extension, sustainability, and strict biological safety protocols. Custom OEM tray sealers have transitioned from basic mechanical heat-sealing fixtures to highly sophisticated thermodynamic instruments. Today's global food processing and medical packaging sectors depend on specialized atmosphere exchange mechanisms to retain freshness without artificial preservatives.
Overall Equipment Effectiveness (OEE) is the gold standard metric for modern packaging lines. System breakdowns, lengthy changeovers, and sealing seal micro-leaks are significant drivers of material waste and product recalls. Collins addresses this with responsive tooling adjustments, digital temperature tracking, and robust structural frames to maintain continuous uptime in high-output plants.

Take a closer look at our raw material selection, high-tolerance machining, and assembly workflows that define Collins machinery quality.
Tailored engineering solutions addressing the regulatory compliance, throughput speed, and safety standards of diverse industrial sectors.
Tray sealing machines must adapt to the unique product characteristics, shelf life goals, and mechanical stresses of each industry. Collins manufactures customized OEM tray sealing machinery tailored to specific commercial operations:
| Application Industry | Primary Challenges | Engineering Solutions & Technologies | Outcome & Advantages |
|---|---|---|---|
| Fresh Meat & Seafood | Rapid bacterial growth, moisture loss, discoloration. | High-barrier film sealing, high-vacuum evacuation, precise O2/CO2 gas backflushing (MAP). | Shelf life extended from 4 days to 14-21 days without freezing. |
| Ready-to-Eat (RTE) Meals | Multi-compartment tray sealing, steam venting requirements, sauce contamination on sealing surfaces. | Profiled sealing plate design, anti-fog films, dual-zone digital heat control. | Leak-free transport, visual product clarity, clean microwave-ready seals. |
| Medical Devices & Pharma | Sterility preservation, particulate control, strict ISO validation. | Tyvek tray sealing, particulate exclusion systems, data logging for validation. | 100% sterile barrier integrity, ISO 11607 compliant packaging validation. |
| Produce & Salads | Trays build up internal moisture; respiration rates cause film expansion. | Micro-perforated film cutting, balanced O2/CO2/N2 gas ratios. | Reduced condensation, prevented tray swelling, sustained product color. |
Integrating next-generation industrial automation, smart sensor arrays, and sustainable packaging processes.
Modern Collins tray sealers feature optional secure Ethernet/Wi-Fi modules. This lets factory teams monitor sealing cycles, pressure fluctuations, and temperature profiles in real-time, enabling predictive maintenance schedules and reduced diagnostic downtime.
We are actively developing and integrating ultrasonic sealing options. By generating localized friction heat directly inside the plastic joint zone, ultrasonic technology seals reliably through liquid residue, oils, and powder contamination, lowering scrap rates on high-speed filling lines.
Recognizing the global push away from non-recyclable multi-layered plastics, our sealing controllers run firmware tailored for compostable and bio-based films. This provides precise heating profiles to seal thin-gauge monofilaments without burning the substrate.
Combining primary machinery, secondary packaging systems, and coding technologies to streamline production.
Henan Collins Machine Co., Ltd. does not simply assemble single machines; we design fully integrated production lines. Our comprehensive equipment and consumables portfolio is built to work together, minimizing compatibility challenges on the factory floor:
Primary Packaging & Bottling Machinery: From VFFS (Vertical Form Fill Seal) systems including the VFFS 420, 520, and 620 models configured for pillow or gusset bags, to automatic multilane sachet machinery for jelly and energy gels. For bottling applications, we provide automatic bottle sorting machinery, glass bottle unscramblers, automatic liquid filling systems, and high-performance induction sealing machines.
Industrial Coding & Traceability: We supply a complete range of industrial coding equipment, including thermal transfer overprinters (TTO), ribbon coders, ink roller coders, and high-speed laser marking systems. These run on high-quality consumables like TTO ribbons, ink rollers, and carbon ribbons, ensuring clean, compliant lot and date codes on every sealed tray, bottle, or sachet.
Secondary Packaging & Shrink Systems: Wrap and consolidate finished goods efficiently using high-speed horizontal flow wrapping machines (like the BG-350 ice cream wrapper) paired with POF/PE film heat shrink tunnels and automatic sleeve applicators.
We design our machines to comply with major international directives. This includes CE safety certificates, RoHS compliance for eco-friendly electronics, and strict ISO 9001 quality audits. When importing equipment, our engineering team modifies electrical wiring, panels, safety enclosures, and emergency stop circuits to match local market regulations, including UL or CSA requirements.
Our customer service model is designed to support international operations. To prevent production downtime, we offer direct line support, virtual troubleshooting, and global dispatch options for on-site commissioning.
Insights from our engineering department regarding machine selection, operations, and optimization.
We use digital proportional gas mixing valves controlled by a central PLC. By continuously measuring and adjusting the vacuum pull pressure down to millibar resolutions, we ensure stable backflush volumes, maintaining a consistent internal environment with residual oxygen levels under 0.5%.
Yes. Our machines are built with adjustable thermal profiles and customizable dwell times. This lets you calibrate pressure and heat to suit different materials, ensuring secure seals on PLA, pulp, and paperboard substrates without burning.
We design our tooling systems for quick, tool-free changeovers. Technicians can swap tray configurations, lock the seals, and load new film rolls in under 10 to 15 minutes, minimizing idle line time.
We incorporate advanced positioning control and drip-free nozzle designs in our filling modules. For sticky materials, we can also integrate air blast mechanisms or specialized product denesters to keep liquid off the tray rim before sealing.
Yes. We construct power configurations (e.g., 220V Single-Phase, 380V/480V Three-Phase, at 50Hz or 60Hz) to match standard utilities in Europe, North America, and other export markets, and source local-spec electrical switchgear for easy maintenance.
Complete your production line with our versatile labeling, filling, sealing, and wrapping machinery.
