Thermoforming Vacuum Packaging Machine
The Thermoforming Vacuum Packaging Machine is an automated rollstock packaging system designed to produce standardized vacuum packs directly from flexible film. Built for continuous commercial food production, it combines package formation with an integrated automated workflow for consistent, repeatable packaging.
Thermoforming Packaging Machine for Continuous Food Packaging
The Thermoforming Packaging Machine forms packaging cavities directly from bottom rollstock film. The formed pockets advance to the loading area, where products are placed before top film is applied. The packages then enter the sealing section for vacuum extraction and heat sealing.
After sealing, the continuous web moves to the cutting section, where the finished packs are separated into individual units. This sequence combines package forming, product loading, vacuum sealing, and pack separation within a continuous rollstock packaging process.

Key Advantages of the Thermoforming Vacuum Packaging Machine
Siemens PLC, 10-Inch HMI and Fault Diagnostics
A Siemens PLC and 10-inch color touchscreen HMI provide centralized control of key packaging parameters and machine functions. Integrated fault diagnostics can stop the machine when an abnormal condition is detected and display relevant alarm information to help operators identify and resolve the issue efficiently.
Precision Printed-Film Registration
A Banner color-mark sensor works with the PLC control system to detect registration marks and synchronize printed top film with the thermoformed pack layout. This helps maintain accurate print positioning when running registered packaging film.
Automatic Film Tension and Brake Control
Automatic braking and tension-control systems maintain stable movement of the top and bottom films throughout the packaging process. Lateral adjustment allows operators to fine-tune film tracking and minimize misalignment during continuous rollstock operation.
Stable Forming and Heat-Sealing Stations
Independent pneumatic lifting and self-locking mechanisms maintain stable positioning of the forming and sealing stations during operation. Interchangeable forming molds allow the thermoforming packaging machine to accommodate different product dimensions and package formats.
Flexible Cross and Longitudinal Cutting
Independent cross-cutting and longitudinal cutting systems can be configured for different pack layouts. Cutting positions and tooling can be adjusted or changed to match the selected mold and finished package dimensions.
Dual-Side Edge-Trim Recovery
A powered edge-trim recovery system continuously collects waste film from both sides of the web after cutting, simplifying scrap handling and supporting cleaner, more organized continuous production.
Reliable Leybold Vacuum Pump
A Leybold vacuum pump provides stable vacuum performance for repeated packaging cycles, supporting reliable air evacuation and consistent vacuum conditions during continuous thermoforming production.
Thermoforming Vacuum Packaging Applications
The Thermoforming Vacuum Packaging Machine is designed for food products that can be arranged in defined pack layouts and processed through continuous rollstock packaging. Typical applications include chilled and portioned meats, sausages and processed meat products, eggs, and selected snack or convenience foods requiring formed package cavities and controlled product placement.
Chilled and Portioned Meat Packaging
Suitable for chilled meat, steaks, portioned cuts, and other regularly shaped meat products packed in formed vacuum cavities for commercial processing, storage, and distribution.
Sausage and Processed Meat Packaging
The thermoforming packaging machine is well suited to sausages and processed meat products that require organized product placement, repeatable pack layouts, and continuous packaging across larger production runs.
Egg and Portion-Pack Packaging
Snack and Convenience Food Packaging
Suitable for selected snack foods and convenience products that can be arranged in formed cavities and packaged in standardized rollstock formats for commercial production and distribution.
FAQ About Thermoforming Vacuum Packaging Machine
Does a thermoforming vacuum packaging machine use preformed pouches?
No. A thermoforming vacuum packaging machine forms individual packaging cavities directly from bottom rollstock film. Products are loaded into the formed pockets, covered with top film, vacuum sealed, and then separated into finished packs.
What is the difference between thermoforming packaging and rolling vacuum packaging?
A thermoforming packaging machine forms the package directly from rollstock film and integrates forming, loading, vacuum sealing, and cutting into one production sequence. A rolling vacuum packaging machine uses preformed vacuum pouches and a moving worktable for repeated batch sealing.
Can the machine use both printed and plain film?
Yes. The machine can operate with plain or printed top film. A photoelectric registration system detects printed registration marks and helps align the printed film with the thermoformed package position during production.
Can one machine produce different package sizes and formats?
Yes. Different mold and cutting-tool sets can be used on the same machine, provided the required package dimensions are within the machine’s working range. The mold configuration is selected according to the product size and required pack layout.
What film specifications should be confirmed before selecting the machine?
The top and bottom film width, film structure, thickness, forming characteristics, sealing compatibility, and whether printed registration is required should all be confirmed. These factors affect mold design, forming performance, sealing, and film tracking.
What vacuum pump configurations are available?
The available vacuum pump capacity depends on the machine model. The DLZ320 is configured with a 100 m³/h vacuum pump, while the DLZ420 and DLZ520 use 200 m³/h vacuum pump systems.
What utilities are required for installation?
The machine requires an appropriate electrical power supply and compressed air of at least 0.6 MPa. Final electrical and utility requirements should be confirmed according to the selected model and machine configuration before installation.
Can coding systems or additional automation equipment be integrated?
Yes. Automatic coding or printing systems can be added according to production requirements. Connection interfaces can also be reserved for robotic handling and other upstream or downstream equipment when further line automation is planned.

A suitable alternative for processors that need continuous high-throughput vacuum sealing with preformed pouches but do not require package forming from rollstock film. It offers a simpler pouch-based workflow for repeated commercial production.
Choose a modified atmosphere packaging machine when products are packed in preformed trays and require gas flushing, tray sealing, and a controlled internal atmosphere rather than thermoformed vacuum packs.
A better fit for products that require close-contact film over a tray or rigid backing board, especially where secure product positioning and retail presentation are more important than continuous rollstock forming.
A practical option for smaller or more flexible batch production using preformed vacuum pouches, particularly when an automated thermoforming line would be unnecessary for the required output or package range.
