The HYL Series Automatic Roll Stock Thermoforming Food Packaging Machine is an advanced integrated packaging solution designed for high-efficiency production lines. As a professional thermoforming packaging machine (also known as roll stock packaging machine or stretch film vacuum packaging machine), it eliminates the need for pre-made containers by completing stretch film forming, material filling, vacuum sealing, and cutting in one continuous process. Equipped with premium components like German original vacuum system and Siemens drive positioning, this machine delivers consistent performance for food, medical, and industrial applications. Available in models DZR620, DZR520, DZR420, and HYL-520/420/320, it caters to diverse production scales with low energy consumption and short cycle times.
The machine integrates AF automatic feeding auxiliary system, automatic quantitative canning system, and laser ink jet printing, realizing fully automated production from material feeding to finished packaging.
US-imported three-color sensor tracking ensures accurate film alignment.
Siemens three-proof electrical cabinet and drive positioning guarantee stable operation in harsh environments.
Swiss customized wear-resistant linear bearings reduce friction and extend service life.
Crafted with food-grade SS304 stainless steel and aviation-grade customized high-strength alloy body, the machine offers exceptional corrosion resistance, high strength, and minimal deformation.
The computer fault intelligent processing system automatically detects issues (e.g., phase loss, high/low voltage, leakage) and stops operation, displaying error reasons. Safety switches and protective covers are installed in key areas for operator protection.
Equipped with a torque-adjustable motor, the scrap recycling process is clean, quiet, and convenient, reducing material waste and environmental impact.

Ideal for packaging cheese, sausage, pickles, fresh meat, seafood, fruit jam, and chilled meat. The airtight vacuum seal locks in freshness and extends shelf life, suitable for large food processing plants and retail brands.
Seals pharmaceutical products, medical equipment, and sterile components. The automated process ensures hygiene and compliance with medical industry regulations.
Protects metal parts, electronic components, and mechanical accessories from rust, dust, and moisture. Perfect for manufacturing and automotive industries.
Load upper and lower film rolls into the machine.
Set parameters (forming temperature, vacuum level, cutting size) via the touch screen.
Start the machine; it automatically completes film forming, filling, vacuum sealing, and waste recycling.
Electric protection against phase loss, high/low voltage, and leakage.
Safety switches and protective covers in molding chamber, heat sealing chamber, and cutting areas.
Automatic machine shutdown and error display in case of faults, preventing accidents.
We provide tailored solutions to match specific production needs:
Mold Customization: Multiple mold options are available; custom molds can be designed for unique product shapes and sizes.
Parameter Adaptation: Adjust film width, vacuum level, and production speed to fit different product requirements.
Component Upgrades: Optional upgrades for advanced coding systems, high-speed feeding, and specialized film compatibility.
No. The machine stretches and thermoforms film on-site, eliminating the need for pre-manufactured containers, reducing costs and increasing flexibility.
All models offer a vacuum level of ≤200 Pa, ensuring strong airtight seals for long-term product preservation.
Yes. Depending on the film material used, the machine can produce both flexible and rigid packages, suitable for diverse product types.
We offer technical consultation, spare parts supply, and on-site maintenance guidance. The intelligent fault system also simplifies troubleshooting.
