High-Efficiency, High-Power Heavy-Duty Vacuum Packaging Machine
Custom-Engineered for 20kg+ Bulk Powders in PP Woven Bags, Kraft Paper Sacks & Aluminum Foil Barrier Pouches
Designed specifically for demanding bulk powder packaging lines, this heavy-duty vertical vacuum packaging system combines high-output vacuum performance with a motorized roller conveyor. It allows single operators to handle 20 kg to 50 kg+ heavy bulk bags effortlessly, ensuring airtight brick-pack or flat-pack vacuum seals without powder leakage or machine downtime.
⚠️ Custom-Engineered Equipment: Built to Your Exact Bag & Production Needs
Because bulk powder applications vary significantly by bag structure, material thickness, and product density, this machine is fully customized rather than built with rigid standard parameters.
To receive an accurate engineering proposal, CAD layout, and quotation, please share the following details with your inquiry:
- 1. Bag Dimensions: Total bag height, width, and required seal width/length.
- 2. Target Weight: Net packaging weight per bag (e.g., 20 kg, 25 kg, 50 kg).
- 3. Bag Material & Structure: Kraft paper composite, multi-layer PP woven, aluminum foil barrier laminate, heavy-duty PE, gusseted pouch, etc.
- 4. Internal Product: Specific product type and powder characteristics (e.g., chemical powders, food additives, flour, starch, milk/protein powder, mineral pigments).
🌟 Dedicated for Fine Powders: Internal Chamber Evacuation (No Suction Nozzles)
Traditional external-probe sealers rely on vacuum nozzles inserted into the bag mouth, which often suck up fine powder, clog air filters, blow powder out of the seal area, and damage the vacuum pump. Our system adopts an enclosed internal vacuum chamber design: the ambient air surrounding the bag is evacuated as a whole, achieving an exceptionally high ultimate vacuum degree without disturbing fine powders, ensuring clean seal areas and zero pump clogging.
