Duplex board with a grey back, commonly referred to as gray-backed board, is a versatile material used widely in the packaging industry. There is also white-backed cardboard, where the front is white and smooth while the back is usually gray. The term "gray-backed board" specifically refers to this dual-sided construction.
In contrast, a white-backed board features a white, smooth surface on both sides, with the core of the paper being gray. This type of cardboard is primarily used for color box printing in the packaging sector, typically for single-sided printing.
This type of board is known for its high rigidity, durability, and smooth finish. The surface is not only smooth but also visually appealing, making it suitable for a variety of packaging needs. Its uniform ink absorption ensures consistent print quality, while the tough paper surface offers excellent folding resistance.
Mainly utilized for single-sided color printing, gray-backed board is then converted into various forms of packaging. It is commonly certified with quality standards such as ISO 9001:2000, ISO 14001:2004, SGS, and FSC, ensuring high environmental and production standards.
