Vacuum & Gas Flush Sealer
Vacuum Heat Sealing Machine
Air is what makes a sealed bag swell, oxidise and take up space. This machine draws a vacuum first, then optionally backfills nitrogen or another gas, and finally clamps a 600 mm seal shut with air pressure rather than a linkage. A 750 W vacuum pump, PLC control and a 304 stainless frame make it a production machine rather than a bench accessory.

Overview
Remove the Air, Then Seal the Bag
Most sealing faults on a vacuum pack come from the seal itself, not the vacuum. A 600 mm seal is long enough that a mechanical clamp struggles to press evenly at both ends. This machine uses compressed air to close the bar, which is why it can hold a reliable seal across the whole width and change the traditional problem of weak seals.
- Three functions in oneVacuum, gas flushing and sealing are carried out in a single cycle, so no pack is handled twice.
- Air-powered clampCompressed air applies even pressure along the 600 mm bar, giving a seal that holds at the corners as well as the centre.
- Fast evacuationA quality vacuum pump rated at 10–20 m³/h removes the air quickly, so cycle time stays short.
- Adjustable heightSeal height is free to set, so short pouches and tall bags run on the same machine.
Vacuum Cycle
What Happens in One Sealing Cycle
Every pack follows the same four stages. Understanding them is what lets an operator tune the vacuum, the gas flush and the seal for a new product.
01
Load
The filled bag is positioned in the chamber with its mouth across the 600 mm sealing bar at the set height.
02
Evacuate
The 750 W pump draws air out of the bag at 10–20 m³/h, collapsing the pack and removing the oxygen.
03
Gas Flush
Optionally, nitrogen or another gas is admitted to replace the air, protecting delicate or crush-sensitive products.
04
Seal
The air-powered bar clamps and heat-seals the mouth in one stroke, closing the pack without trapped air.
No Swelling
Removing the air stops the pack ballooning in transit and keeps the pallet stable.
Less Oxidation
With the oxygen drawn out, oxidation of oils and powders slows and shelf life improves.
Smaller Volume
Flatter packs stack and transport more efficiently, which lowers the space a shipment occupies.

Bag Fit
Matching the Cycle to the Product
Not every product wants a hard vacuum. This table maps the common pack types to the cycle that protects them best.
| Bag Type | Typical Product | Cycle | Notes |
|---|---|---|---|
| Plastic bag | Dried food, hardware, sundries | Vacuum | Standard film, 600 mm seal |
| Composite bag | Meat, seafood, powders | Vacuum and optional gas | Barrier film holds the vacuum without stretching |
| Aluminium foil bag | Chemicals, electronic components | Vacuum and gas flush | High barrier and moisture protection |
| Heavy gauge bag | Grain, feed, bulk goods | Gas flush | Avoids crushing the contents under full vacuum |
| 550 × 900 mm bag | General packing | Vacuum | Reference bag size for this build |
Bag size, gas type and vacuum level are confirmed against your product before production. The sealing clamp requires compressed air on site.
Advantages
Built for Real Packing Rooms
Stainless steel where it is washed, castors where it is moved, and a PLC where settings must repeat.
Hygienic Frame
A 304 stainless steel structure is durable and easy to clean, which suits food, pharma and chemical rooms.
PLC Control
A PLC with an LCD panel stores and repeats the vacuum, gas and seal settings for each product.
Braked Castors
The machine moves on castors but locks in place, so it stays stable under the load of a full bag and a heavy seal.
Imported Components
Reliable imported parts keep performance stable across long production runs.

FAQ
Vacuum Heat Sealer Questions
A plain sealer closes the bag with the air still inside. This machine draws a vacuum first, so most of the air is removed before sealing, then optionally backfills the bag with nitrogen or another gas. That stops the pack ballooning, reduces oxidation of the contents and cuts the transport volume.
Pneumatic sealing applies a firm, even clamp across the whole 600 mm seal, which is harder to achieve with a mechanical linkage at that length. The result is a seal that does not leak at the ends, which is the usual failure point on a wide bag and the reason many traditional sealers give a weak seal.
The standard seal length is 600 mm with an 8 mm seal width, sized for bags around 550 x 900 mm. It seals plastic and composite bags used for vacuum and gas-flushed packing in food, pharmaceutical, chemical and electronic products, where the film has to hold a vacuum without stretching.
Yes. The machine can draw a vacuum and then admit nitrogen or another gas before sealing, which is the usual route for products that would be crushed by a hard vacuum or that need a controlled atmosphere to stay fresh.
The sealing height adjusts freely, so the same machine can seal short pouches and tall bags without a table change. The frame sits on castors with a braking system, so once the height and position are set the machine stays where it is put.
Control is through a PLC with a liquid crystal display panel. The machine is assembled and tested before dispatch and ships in heavy double-layer packing. Standard production is about 5 working days with express transit of roughly 4 to 6 working days, and a 2-year warranty applies.
