1. Understanding Powder Packing

Powder packing refers to the process of filling powders—such as spices, flour, chemicals, pharmaceutical powders, and powdered milk—into individual containers, bags, or pouches. Proper packing is essential to:

• Maintain product quality and prevent contamination.
• Ensure precise weight or volume per package.
• Enhance product shelf life and storage efficiency.
• Facilitate transportation and retail distribution.

Manual methods rely on human operators to measure, fill, and seal packaging, whereas automated machines streamline this process through advanced mechanical and electronic systems.
