This vffs packaging machine packs powder products into bags from roll film, then checks weight and metal contamination after sealing. It works for milk powder, flour, protein powder, seasoning powder, coffee powder, chemical powder, and similar dry powders. The powder packaging machine fits food factories, supplement plants, and powder processing lines that need filling, sealing, checking, and rejection in one layout. For buyers comparing vffs machine manufacturers, this model gives a more complete powder packing line than a basic VFFS machine.
