Applications of WLC & Double White Paperboard
-
In folding carton applications, material selection mainly depends on packaging design requirements and performance needs. White Lined Chipboard (WLC) and Double White Paperboard are two structural variants of the same folding carton board family, widely used for packaging applications that require excellent printability, high stiffness, and stable converting performance.
-
It is commonly applied in electronic product packaging such as mobile phone boxes, tablet packaging, earphone boxes, small home appliance boxes, and accessory packaging, as well as other consumer folding carton applications.
-
The top surface features a smooth coated white layer suitable for high-quality color printing, while the grey recycled fiber back provides stable stiffness and structural support, making it suitable for various folding carton structures.
-
Overall, WLC and Double White Paperboard combine excellent printability and structural stability, making them ideal for electronic, cosmetic, and consumer folding carton packaging.

FAQ
1. What is White Lined Chipboard (WLC) and why is the back side grey?
White Lined Chipboard (WLC) is a recycled paperboard with a coated white printing surface on the top side and a grey recycled fiber back. The grey back is made from recycled pulp, which helps improve cost efficiency and structural stability for folding carton applications.
2. What is duplex board (WLC) used for in packaging?
It is mainly used for folding carton packaging such as mobile phone boxes, tablet packaging, earphone boxes, small home appliance packaging, cosmetic cartons, and retail packaging.
3. Is grey back duplex board recyclable?
Yes. White Lined Chipboard (WLC) is made from recycled fibers and is fully recyclable, making it a widely used eco-friendly packaging material.
4. What is the difference between duplex board and ivory board in printing quality?
Ivory board (SBS/FBB) generally offers higher whiteness, smoother surface, and premium print quality. Duplex board (WLC) provides good printability with a more cost-efficient recycled structure, making it suitable for mid-range folding carton packaging.
5. What is the difference between White Lined Chipboard (WLC) and solid white board (SBS/FBB)?
White Lined Chipboard (WLC) is made from recycled fibers with a grey back, offering a cost-efficient solution for folding carton packaging. SBS/FBB boards are made from virgin or higher-grade pulp, providing higher brightness and premium printing quality, and are typically used for high-end packaging.
6. How do I choose the right paperboard for folding carton packaging?
The selection depends on packaging requirements such as print quality, stiffness, product type, and budget. WLC is commonly used for medium-grade folding cartons such as electronics and consumer packaging, while higher-grade boards are selected for premium packaging needs.
