The rugged solution for DIY Construction Powders. This Heavy-Duty VFFS machine packs fine powders like Tile Grout, Wall Putty, and Gypsum into 1kg-5kg bags. It features a specialized De-aeration System to squeeze air out of the product, preventing "balloon bags" and ensuring stable palletizing.
Are your powder bags puffy and hard to stack? Fine construction powders trap a lot of air during filling, resulting in "balloon bags" that burst during transport or slide off pallets. The LTC Construction Powder Machine solves this with a dual-stage De-aeration System. It uses a specialized auger probe and external rollers to force air out of the product before and after sealing, creating a solid, brick-like brick pack.
Air Expeller (De-aeration): Removes excess air from the bag to reduce volume and prevent bursting.
Abrasion Resistant: The auger screw and filling tube are hardened to withstand the wear and tear of abrasive materials like sand and cement.
Heavy-Duty Pulling Belts: Reinforced vacuum belts ensure reliable film transport for heavy bags (up to 5kg).
Dust-Tight Sealing: Special jaw design ensures a hermetic seal even in extremely dusty environments.
Designed for the DIY and Hardware market (1kg - 5kg bags):
Tile Grout / Joint Filler
Wall Putty / Skim Coat
Plaster of Paris / Gypsum Powder
White Cement
Dry Mix Mortar

Q: Can this machine handle abrasive powders containing sand?
A: Yes, we use hardened steel or ceramic-coated auger screws to resist abrasion from sand and silica content.
Q: Why do I need de-aeration?
A: Without it, your bags will be full of air. De-aeration makes the bag smaller (saving box space) and flatter (safer for pallet stacking).
