M-450Semi-Automatic MAP Tray Sealer
MAP tray sealing for your tray format. You load the trays by hand; the machine runs the vacuum, gas filling, sealing and cutting cycle.

*Nominal value. Actual output depends on product, tray, film, gas mixture and settings.
Applications
Fresh meat, prepared foods, fresh-cut fruit and portioned products in sealed trays.
How the M-450 Works
Vacuum-replacement MAP. The tray sits in a closed chamber; the machine evacuates it, fills it with the gas mixture, then seals and cuts the lidding film.
- 01
Vacuum Replacement
Closed-chamber evacuation, then controlled gas filling.
- 02
Gas Mixing
One, two or three gases, usually CO₂, N₂ and O₂. Mixing accuracy better than ±2%.*
- 03
PLC & Touchscreen
Siemens controls. Parameters are set once for each packaging material.
- 04
Changeable Tooling
Tool-free mold removal for format changes and cleaning.
Key Machine Modules
Control Panel
Touchscreen, two-hand start and temperature controllers.
Tray Tooling
6061 aluminum tooling made to your tray samples.
Film Handling
Lidding film roll with photoelectric print registration.
Sealed Trays
Trays sealed, cut and released in one cycle.
Trays and Film
The tooling is made to your tray. We check your tray and film before you order.
Tray Tooling
We check
- Tray shape and flange
- Tray size, up to 350 × 490 mm
- Tooling layout for your tray
Lidding Film
We check
- Composite, mono or co-extruded film
- Printed film registration
- Film width up to 450 mm, roll diameter up to 260 mm
Send us your trays and film before you order, so the tooling and settings fit them.
Technical Specifications

Test It With Your Tray
The speed is a nominal value. Your output depends on the product, tray, film and gas mixture, so we test with your tray and film before you order.

- Product and its condition
- Tray samples or drawing
- Lidding film
- Gas mixture requirement
- Required output
Guides
Buying and setup questions about this machine.
What does semi-automatic mean on the M-450?
You load the trays into the machine and take them out by hand. Vacuum, gas filling, sealing and cutting run automatically once the cycle starts.
Which gases can it use?
It can be set up for one, two or three gases, usually CO₂, N₂ and O₂. The gases and the mixing ratio are chosen for your food.
Is the gas replacement rate the same as residual oxygen?
No. The ≥ 99.5% gas replacement rate is a nominal value from the technical sheet, not a residual oxygen specification. Results depend on the product, tray, film, gas mixture and settings.
Can the tooling fit my tray?
Yes. The tooling is made to your actual tray samples, and the maximum tray size is 350 × 490 mm. Send us your tray before you order.
How do I choose between the M-450 and the T680?
The M-450 suits smaller batches and lines where trays are loaded by hand. The T680 is automatic and also runs VSP and seal-only packs, for continuous production.
