1. Polypropylene Bags One of the most commonly used materials today is polypropylene, a durable plastic that provides excellent moisture resistance. These bags are lightweight, cost-effective, and can be printed with high-quality designs. They often come equipped with features like resealable closures to enhance convenience for consumers.

2. Regulatory Compliance Depending on the product being packaged—especially food items—businesses must ensure their packaging complies with relevant health and safety regulations. This may involve using food-safe inks and materials.

Flour is traditionally packaged in paper bags for several reasons, which stem from both practicality and cost-efficiency. The nature of flour itself—fine and powdery—makes paper a suitable material because it can contain the flour without requiring an airtight seal. Paper bags are also breathable, which prevents condensation and keeps moisture levels low, protecting the flour from spoilage and mold.
