Explore our premium engineered portfolio of automatic L-Bar sealers, bottle neck capping wraps, stretch blow-molding auxiliaries, and food-grade heat wrap systems built to international enterprise standards.
In modern industrial manufacturing and global supply chains, secondary product packaging acts as the critical barrier preserving product safety, freshness, and structural stability. For food processors, consumer goods manufacturers, and pharmaceutical suppliers, investing in heavy-duty tray sealing machines and automatic shrink wrapping tunnels represents a direct mechanism for lowering total cost of ownership (TCO) while securing a high yield rate.
As standard retail and logistics systems tighten compliance requirements, packaging automation can no longer rely on fragmented operations. A unified technical workflow, integrating high-speed sealing jaws with uniform thermal shrinking, eliminates weak seal boundaries, prevents leakage, and protects contents from humidity, dust, and tampering.
Tray sealing technology is no longer limited to high-barrier modified atmosphere packaging (MAP). Today, it forms a symbiotic relationship with shrink-wrap overwrappers. Combining a robust tray base with high-clarity POF or PVC sleeve shrink tunnels allows enterprises to:
Analyzing mechanical structures, material thermodynamics, and system safety components engineered to fulfill critical production line demands.
Integrated micro-switches regulate sealing pressure. High-durability alloy sealing blades treated with high-grade PTFE (Teflon) prevent film sticking and maintain precise cutting paths under high-temp runs.
Optimized dual-air recirculation fan systems blow high-speed heat evenly over the surface of POF/PVC wrap. This prevents heat spots, prevents structural melting, and ensures uniform wrinkle-free contraction.
Using servo-driven horizontal knives, machines maintain continuous horizontal sealing motion without stopping feed conveyors, offering higher speeds and clean cuts for heavy-duty box or tray wraps.
Enabling custom high-strength stretch films and hood materials. Multi-layer configuration ensures exceptional puncture resistance, high elastic retention, and superior water-proofing for pallet packaging.
Systems can connect directly to upstream production units, such as filling systems, secondary tray formers, labeling machines, or downstream robotic palletizers for continuous flow.
Shanghai Jinye Machinery Co., Ltd. is a professional manufacturer specializing in the research, development, design, production, and service of advanced packaging machinery. Headquartered in Shanghai, China, the company has established a modern manufacturing base equipped with advanced processing facilities and strict quality management systems, enabling us to deliver reliable and efficient packaging solutions to customers worldwide.
Founded with a commitment to innovation and customer satisfaction, Shanghai Jinye Machinery has accumulated extensive experience in the packaging machinery industry. Our main products include hooding machines, shrink wrapping machines, sleeve wrapping machines, automatic packaging lines, pallet packaging systems, and other customized packaging equipment.
Driven by continuous technological innovation, we integrate sales, research and development, mechanical design, precision manufacturing, electrical engineering, assembly, commissioning, quality inspection, and after-sales service into a complete one-stop operation. We continuously invest in advanced CNC machining centers, laser cutting equipment, precision bending machines, and modern manufacturing technologies to ensure high precision, stable performance, and excellent product quality.
Our manufacturing process is carried out under a comprehensive quality management system, and our equipment is designed and manufactured in compliance with international standards. We are committed to providing safe, efficient, energy-saving, and intelligent packaging solutions that help customers improve production efficiency, reduce labor costs, and enhance packaging quality.
By keeping processing steps in-house—including shearing, bending, machining, and final assembly—we ensure high mechanical tolerances and components designed to last.
As food manufacturers target circular economy benchmarks, packaging machinery design must keep pace. Shanghai Jinye Machinery builds solutions optimized for traditional and alternative film structures.
Our heating tunnels feature dual digital PID temperature controllers. PVC requires lower temperatures but generates corrosive gas, requiring our standard anti-corrosion, chrome-coated heaters. POF demands high heat and strong airflow, which are provided by our variable-frequency drive blower fans.
To accommodate PLA, starch-based, and PCR (Post-Consumer Recycled) films, our packaging lines feature high-precision pressure sensors. These calculate film stress in real-time, preventing film snaps and maintaining clean sealing margins.
Our electrical panels support Profinet, EtherCAT, and Modbus TCP interfaces. Users can monitor sealing temperatures, cycle speeds, and pneumatic pressures directly via terminal HMI panels or from centralized ERP production control dashboards.
