Flute, also called corrugation, is used to strengthen or reinforce the cardboard that's used in your packaging. They typically look like wavy lines which when glued to a paperboard, forms the corrugated board. Fluting in packaging gives your packaging the rigidity and helps withstand any crushing.
Flute is categorized by thickness of paper being folded (fluting paper). This can range from single walled flutes, which are smaller flutes but provide better printability and foldability. Larger flutes, which are typically double walled flute and above, provide greater strength and cushioning, making them ideal for shipping.
