There are many reasons why powder in bulk bags can stick together.
Here is a list of the 9 most common causes:
1. Hygroscopy
Some powders have a natural ability to absorb moisture from the air. When powder absorbs moisture, it can become sticky and form agglomerates.
2. Compression
When powder is stored in a bulk bag, the pressure exerted by the weight of the powder can cause it to compress, resulting in the formation of solid blocks.
3. Temperature
Fluctuations in temperature can cause moisture to condense in the bulk bag.
When the temperature drops, moisture can condense on the walls of the bulk bag as wall as on the powder leading to product agglomeration.
4. Chemical composition
Certain chemical compounds can react with each other, forming strong bonds.
For example, if the powder contains compounds that react with moisture, this can lead to the formation of agglomerates.
5. Particle size
Fine particles can agglomerate more easily than larger ones. Fine particles have a greater specific surface area, which means they have more points of contact with other particles, which can favor agglomeration.

6. Storage time
The longer the powder is stored in the bulk bag, the more likely it is to agglomerate. This is due to moisture build-up, powder compression and other factors that can promote agglomeration.
7. Movement
Vibrations or movements of the bulk bag can cause friction between particles, which can lead to agglomeration.
8. Residual moisture
If the powder has not been dried properly, or if it contains a certain amount of residual moisture, it may agglomerate. Residual moisture may come from the powder's manufacturing process, or from the environment in which it is stored.
9. Electrostatic charge
Static electricity can attract particles to one another, promoting agglomeration.
Electrostatic charge can be generated by particles rubbing against each other or by other sources, such as humidity.
