Bagging and Flexible Packaging Sealing Equipment

25kg Heavy Bag Continuous Sealer

The 25kg heavy bag continuous sealer handles heavier bagged products through load-bearing conveying, bag mouth guiding, and continuous heat sealing. 25kg indicates the heavy bag application level, not that all bag types are directly compatible; bag material, bag mouth layers, dust, bag center of gravity, and conveying height must be confirmed based on filled bag samples.

Technical parameters

Capacity and Cycle Time: Confirmed based on bag weight and spacing, conveying stability, bag mouth organizing, heat sealing/cooling, and manual coordination; fixed values not published without project v...
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 straighten...

Selection guide

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, gusseting, sewing, coding, and inspection are optional modules
25kg is an application level description; actual load capacity and cycle time confirmed per project

Applications

Projects using 25kg heavy bags for powders, granules, or industrial raw materials
Lines requiring load-bearing conveying and continuous heat sealing of inner liners or plastic bag mouths after filling
Production lines with dusty bag mouths, gussets, or multi-layer structures needing special organizing
Heavy bag lines planning to add optional dust removal, sewing, coding, or inspection

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 pe...
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.
