Check applicable objects first
Vacuum bags or composite pre-made bags with uniformly positionable bag mouth and bag thickness suitable for 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.

Continuous bag conveying and sealing operation video
Local silent video only shows bag mouth positioning, continuous conveying, and sealing process; evacuation effect of transparent empty bags is not obvious; this clip is not used to prove vacuum level or fixed cycle time.
See actual conditions first
Bag thickness, bag mouth position, and vacuum sealing must be confirmed simultaneously
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.
Bag thickness, bag mouth position, and vacuum sealing must be confirmed simultaneously
- Continuous conveying and bag mouth guide designed according to bag thickness and bag mouth position after bagging
- 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
Information recommended before quotation
- 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

Common configuration routes
Steps from sample confirmation to delivery
The more complete the samples, packaging materials, and site information, the easier it is to determine equipment route, changeover scope, and line integration boundaries.
Confirm bag mouth position, bag thickness, material distribution, and feeding posture.
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 inlineContinuous feeding of bagged products, suitable for projects with relatively stable bag mouth and thickness.
Horizontal pre-made bagThe machine picks up and opens bags, fills, then vacuum seals; automation scope differs.
Rotary vacuumMulti-station or multi-chamber cyclic processing, suitable for different loading and cycle routes.
Continuous bag vacuum sealing
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.

Frequently Asked Questions
Please provide empty bags and filled products, materials, bag mouth position, vacuum appearance, sealing standards, target cycle time, and site interfaces.
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.
Send samples and requirements
