DESCRIPTION
The ZONESUN ZS-DLZ420 thermoforming vacuum packaging machine combines lower-film forming, a product-loading area, vacuum sealing and package cutting in one production line. A SUS304 stainless steel frame and touchscreen controls support setup for compatible food packaging applications.
Listed operating efficiency is 5–7 cycles per minute, not individual packs per minute. Finished-pack output depends on the mold layout, product dimensions, loading method, film and process settings.

Configuration note: The specification lists 380V / 50Hz, while the voltage selector also lists 110V and 220V. Confirm the complete machine's electrical requirements before purchase. The listed forming vacuum pressure of 0.15 MPa is retained as supplied; confirm its pressure reference and measurement point with the technical team. Verify compressed-air supply, vacuum equipment, installation access and included accessories for the quoted configuration.
Touchscreen Control Panel
Set operating parameters, monitor machine status and access troubleshooting functions through the touchscreen. The illustrated panel includes Chinese and English language selection alongside physical run, stop and emergency-stop controls.
Lower Film Forming
The lower film feeds into the heated forming station, where it is shaped into product cavities. Match the film specification and forming mold to the required package dimensions and product depth.
Upper Film Sealing
Upper film covers the loaded cavities for vacuum sealing and heat sealing. Film compatibility, sealing temperature, dwell time and the condition of the seal area must be matched to the product and package.
Horizontal and Longitudinal Cutting
The cutting system separates the sealed film web into individual packages. Confirm the cutting layout, cavity arrangement and finished-pack dimensions when specifying tooling.
Film Trim Collection
The illustrated reel collects excess film edges after cutting, helping keep trim organized at the discharge end of the machine.
Selection and Ordering Guide
Provide product samples, length, width, height, target pack weight, desired cavity layout, film details and required finished-pack output. Confirm mold dimensions, forming depth, loading arrangements, utility requirements and the equipment included in the quotation. Film width and maximum forming depth are not specified here and should be confirmed before ordering.
Frequently Asked Questions
Does the ZS-DLZ420 use premade vacuum bags?
The illustrated process uses lower roll film to form cavities and upper roll film to seal them. It is a thermoforming packaging workflow rather than a machine for loading individual premade bags.
Does 5–7 cycles/min mean 5–7 finished packs/min?
No. Cycles refer to machine operations. The number of finished packs depends on how many cavities are produced in each cycle, as well as product loading and process settings. Confirm output using the proposed mold layout and product samples.
Is a shrink tunnel included?
The illustrated line identifies forming, loading, sealing, cutting and film collection stations; a separate shrink tunnel is not identified. Do not assume a post-sealing shrink stage is included. Confirm any shrink-film process and additional equipment in the quotation.
What power and compressed air are required?
The published specifications list 380V / 50Hz, maximum power of 10 kW and compressed air pressure of at least 0.6 MPa. Because the selector also lists 110V and 220V, confirm the exact electrical configuration and air demand before installation.
Why Choose the ZS-DLZ420?
The ZS-DLZ420 brings film forming, vacuum sealing and package separation into one line. Its touchscreen interface, SUS304 stainless steel frame and organized film-trim collection provide a practical basis for configuring a repeatable packaging workflow around a tested product and film combination.
Ideal Applications
Consider the ZS-DLZ420 for compatible portioned-food packaging projects that require formed film cavities and vacuum-sealed top film, such as tested corn, sausage, bean, nut and seafood packs. Confirm package geometry, product handling and storage requirements with samples before finalizing the machine configuration.
