Duplex board, a versatile paperboard material, has become essential in modern packaging and printing industries. This laminated paper substrate features two distinct layers bonded together - typically a high-quality top layer and a coarser bottom layer - providing exceptional printability and structural integrity. With increasing demand in food packaging and premium consumer goods, understanding the technical specifications and advancements in duplex board is critical for manufacturers and packaging designers.

According to the International Corrugated Packaging Association, the global paperboard market is projected to reach $285 billion by 2027, with duplex board accounting for over 25% of food-grade packaging solutions. Technological innovations in coating processes have enabled enhanced moisture resistance and print fidelity, expanding applications across diverse industries.
