Check applicable objects first
Prefilled vacuum or laminated premade bags with a consistently positionable mouth and a filled-pack thickness suited to continuous conveying
Continuous bag vacuum sealing
Continuous External-Vacuum Bag Sealing Machine
The machine conveys, externally evacuates and heat-seals prefilled bags. Confirm barrier structure, mouth flatness, product dust or liquid migration, headspace and sealant layer, then validate evacuation time, pack shape, seal strength, leakage and continuous transport with the actual product and bag.

Confirm filled-pack thickness, pouch-mouth position and vacuum sealing together
Please provide empty bags and filled products, materials, bag mouth position, vacuum appearance, sealing standards, target cycle time, and site interfaces.
Packaging materials and process must match
Pre-made bags with appropriate barrier and heat sealing properties; bag width, bag thickness, bag mouth flatness, and heat seal layer verified per sample; bagged product feeding, bag mouth positioning, vacuumizing, optional gas flushing, heat sealing, cooling, and continuous discharging
Optional modules are not standard
Optional upstream bag arranging, liquid trapping, gas flushing, seal inspection, rejection, and downstream conveying.
Parameters confirmed per project
Please provide empty bags and filled products, materials, bag mouth position, vacuum appearance, sealing standards, target cycle time, and site interfaces.

Information recommended before quotation
The more complete the samples, packaging materials, and site information, the easier it is to determine equipment route, changeover scope, and line integration boundaries.
Configuration reference
- Continuous conveying and pouch-mouth guides are designed around the filled pack thickness and pouch-opening position.
- Vacuum treatment, heat sealing, and cooling jointly verified through actual filled bag samples
- Liquid trapping, gas flushing, inspection, and rejection are optional modules
- Actual cycle time, vacuum time, and utilities confirmed per configuration and feeding stability
Prepare for selection
- Empty bags and filled products, bag width, bag thickness, and bag mouth position
- Material liquid content, dust, sharp edges, pressure resistance, and temperature conditions
- Target vacuum appearance, seal strength, or leak acceptance criteria
- Feeding method, target cycle time, vacuum source, and upstream/downstream interfaces

Key Parameters
Capacity and cycle time
Confirmed based on manual or automatic feeding, bag mouth positioning, vacuum processing time, sealing cooling, and product spacing. Actual capacity is confirmed by project trials.
Automation scope
Continuous conveying, vacuum, and sealing; upstream bag feeding, liquid trapping, gas flushing, inspection, and downstream conveying optional per project
Applicable containers or packaging
Vacuum bags or composite pre-made bags with uniformly positionable bag mouth and bag thickness suitable for continuous conveying
Applicable materials
Food, parts, granules, or other bagged products; liquid content, dust, sharp edges, pressure resistance, and temperature must be specified
Packaging materials and consumables
Pre-made bags with appropriate barrier and heat sealing properties; bag width, bag thickness, bag mouth flatness, and heat seal layer verified per sample
Basic process
Bagged product feeding, bag mouth positioning, vacuumizing, optional gas flushing, heat sealing, cooling, and continuous discharging
Tooling and changeover
Adjust conveying, guides, vacuum port, sealing, and cooling structure according to bag width, bag thickness, bag height, and bag mouth position
Power, air supply, and layout
Equipment dimensions, power, air supply, maintenance space, and upstream/downstream interfaces confirmed based on vacuum system, continuous conveying, sealing heating, cooling, and optional gas and inspection modules
Steps from sample confirmation to delivery
Confirm pouch-mouth position, filled-pack thickness, product distribution and infeed orientation.
Verify liquid/dust migration, product deformation, bag mouth, and heat seal window.
Check feeding spacing, bag mouth guide, cooling, and abnormal stop.
Check vacuum appearance, sealing, cycle time, continuous operation, and changeover.
Common configuration routes
Compare continuous, horizontal pre-made bag, and rotary vacuum solutions
A continuous external-vacuum machine accepts the mouth of a prefilled bag into the sealing zone; a chamber machine places the whole bag in a chamber. Vacuum level alone cannot make them interchangeable.
Continuous inline
Continuously feeds prefilled packs; suitable when pouch-mouth position and filled-pack thickness stay relatively consistent.
Horizontal pre-made bag
The machine picks up and opens bags, fills, then vacuum seals; automation scope differs.
Rotary vacuum
Multi-station or multi-chamber cyclic processing, suitable for different loading and cycle routes.

Frequently Asked Questions
Can it run continuously with large variations in bag thickness?
The adaptability range of conveying, bag mouth guides, and vacuum station needs evaluation; excessive variation may require separate production by specification or added adjustments.
Can products with liquid be vacuumized?
It can be evaluated, but liquid migration may contaminate vacuum and sealing; filling amount, temperature, and bag mouth need control, and optional liquid trapping should be considered.
