Check Applicable Objects First
Plastic bags, composite bags, or lined bags with fill weight approximately 25kg or similar heavy-duty applications; actual weight and bag type confirmed per sample
Heavy Bag Load-Bearing Conveying and Continuous Sealing
Heavy-Duty Continuous Bag Sealer for Approx. 25 kg Applications
For approximately 25 kg-class or similar heavy-duty bag applications. Confirm actual filled weight and center of gravity, bag and liner construction, mouth layers and folds, dust or trapped product, conveyor height and seal acceptance. The 25 kg reference is not a fixed claim for every bag type.

Recommended Information 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
- Load-bearing conveying and bag straightening confirmed by filled bag weight, center of gravity, and shape
- Bag mouth guiding, heat sealing, and cooling verified based on bag material layers and contamination
- Dust removal, bag-mouth folding, bag sewing, coding and inspection are optional modules.
- 25kg is an application level description; actual load capacity and cycle time confirmed per project
Prepare for selection
- Filled bag product, actual weight range, bag width/height, and center of gravity
- Bag material structure, liner, bag mouth layers, gusset, and heat seal layer data
- Dust, bag mouth contamination, seal strength, and transport acceptance standards
- Conveyor height and direction, target cycle, power supply and downstream palletizing interface

Key Parameters
Capacity and Cycle Time
Confirmed based on bag weight and spacing, conveying stability, bag mouth organizing, heat sealing/cooling, and manual coordination. Actual capacity is confirmed by project trials.
Automation Scope
Heavy bag load-bearing conveying and continuous sealing; bag mouth cleaning, dust removal, gusseting, sewing, and inspection are optional per project
Applicable Containers or Packaging
Plastic bags, composite bags, or lined bags with fill weight approximately 25kg or similar heavy-duty applications; actual weight and bag type confirmed per sample
Applicable Products
Powders, granules, raw materials, or industrial products; dust, temperature, bag mouth contamination, center of gravity, and conveying stability must be specified
Packaging Materials and Consumables
Bag mouth materials or liners suitable for continuous heat sealing; layers, thickness, coating, gusset, and seal width confirmed per bag sample
Basic Process
Filled bag load-bearing conveying, bag straightening, bag mouth organizing and guiding, continuous heat sealing, cooling, and discharge
Tooling and Changeover
Adjust conveying, bag guiding, sealing, and cooling structures according to bag width, height, fill weight, bag mouth layers, and seal position
Power, Air Supply, and Layout
Determine equipment dimensions, power, air supply, maintenance space, and upstream/downstream interfaces based on load-bearing conveying, sealing heating/cooling, bag straightening, dust removal, and optional sewing equipment
Steps from Sample Confirmation to Delivery
Confirm actual weight, center of gravity, bag stability, bag mouth, and dust conditions.
Test bag mouth organizing, temperature, pressure, cooling, and seal strength.
Check straightening, spacing, seal position, discharge, and emergency stop.
Use agreed filled bag product to check sealing, cycle time, load capacity, and changeover.
Common Configuration Routes
Compare Standard Continuous Sealing, Heavy Bag Sealing, and Sewing Combinations
Continuous heat sealing, sewing, folding-and-sewing and liner heat sealing suit different bag constructions and sealing targets; dust and trapped product can change the route.
Standard Continuous Sealing
Suitable for lighter bagged products, with relatively lower requirements for conveying and bag support.
Heavy Bag Continuous Heat Sealing
Equipped with load-bearing conveying and bag straightening, verify bag mouth guiding with filled bag product.
Heat Sealing Plus Sewing
Optional bag sewing or top-folding station for projects requiring two-stage bag-mouth closing.

Frequently Asked Questions
Does 25kg mean all 25kg bags can be sealed directly?
No. Bag material, bag width, bag mouth layers, filled bag shape, center of gravity, and conveying conditions must also be checked; actual load capacity confirmed per sample.
Is sewing required after heat sealing?
Depends on bag material and logistics requirements. Sewing can be an optional station, confirmed together with inner liner heat sealing, gusseting, and bag mouth structure.
Send Samples and Requirements
