Duplex board cartons are versatile and cost-effective packaging solutions made from a two-ply paperboard, featuring a white-coated exterior for a clean appearance and a grey interior. These cartons are commonly used for a wide range of products due to their durability and strength. The duplex board provides a balance of rigidity and lightweight characteristics, making it suitable for everything from food packaging to industrial products. The white outer layer allows for good printability, while the grey core offers added strength and a more economical choice for various packaging needs.
