A 5-ply corrugated box is a sturdier type of packaging box, made from five layers of material. It is designed to offer enhanced strength and protection compared to a 3-ply corrugated box.

• Increased Strength: The additional layers of fluting and linerboard make 5-ply boxes significantly stronger and more durable than 3-ply boxes.
• Greater Protection: Ideal for heavy, fragile, or valuable items, as the extra layers provide superior resistance to crushing, impacts, and moisture.
• Heavier Weight: Due to the additional material, 5-ply boxes are heavier and more robust, which can slightly increase shipping costs but offers better protection.
