Detailed Description
Carbon black, toner and iron-oxide pigment are ultra-fine powders that fly easily and absorb moisture. Specialised powder valve bags fill dust-free with a self-sealing valve; an optional film liner adds a moisture barrier to prevent powder escaping or caking.
The block-bottom structure leaves a flat base after filling, so bags stack stable for warehouse and transit; width, length, valve position and print are customised to your recipe weight and packing speed.
Material is selected by powder particle size and humidity — high-density kraft or paper–plastic composite, all custom. Paper cost flexes with your budget.
