Duplex kraft back paper is a type of paperboard that combines the characteristics of kraft paper and a white coated surface. Here are the key features of duplex kraft back paper:

1. Dual-sided Composition: Duplex kraft back paper consists of two layers – a kraft paper layer on one side and a coated white layer on the other. This dual-sided composition provides a balance between the strength of kraft paper and the printability of a coated surface.
2. Natural Brown Appearance: The kraft side of the paper typically retains a natural brown color, offering a rustic and environmentally friendly aesthetic, while the coated side provides a clean, white surface for printing.
3. Versatility: Duplex kraft back paper is versatile and finds applications in various industries, including packaging, display materials, and promotional items. The kraft side is often used for the interior of packaging, while the coated side is suitable for high-quality printing.
4. Strength and Durability: The kraft layer contributes to the strength and durability of the paper, making it suitable for applications where a sturdy material is required.
5. Printability: The coated white side of duplex kraft back paper allows for excellent printability. This makes it an ideal choice for projects where both visual appeal and structural strength are essential, such as packaging with printed graphics.
6. Environmentally Friendly: Similar to traditional kraft paper, duplex kraft back paper is often considered environmentally friendly, especially if it is made from recycled materials or sourced sustainably.
