FSC 3mm Uncoated Rigid Grey Chipboard Smooth Double Grey Craft Cardboard For Packaging Backing

Sunxiang FSC rigid grey chipboard (double grey board) is an uncoated solid grey craft cardboard with a smooth, plain surface. The 3mm (3000 micron) thickness is one of our most popular specifications, offering outstanding stiffness, good flatness and stable physical performance. It is widely used as a backing substrate, for book binding, as rigid box inner support and as a stationery base material. Custom thickness and sheet sizes are available for different converting projects.

• Excellent Rigidity & High Stiffness: The solid grey chipboard structure delivers strong load-bearing performance and resists bending or deformation, making it ideal for applications requiring stable support and a rigid structure.
• Smooth Uncoated Flat Surface: No clay coating, with a uniform smooth grey surface. Consistent flatness reduces warping and suits laminating, pasting, die-cutting and manual finishing.
• Stable Physical Performance: Uniform fibre structure, low moisture fluctuation and good punching and creasing properties ensure steady performance during automatic die-cutting and folder processing.
• FSC Sustainable Material: FSC certified raw pulp meets green packaging and eco-compliance requirements for export orders.
• Customizable: Multiple grammage and thickness options available. We can cut to custom sheet sizes according to customer drawings.

• Picture frame backing boards, art print and painting support plates
• File folders, document covers, book binding and book cover substrate

1. Strong supportive property: A perfect backing material to keep frames, folders and boxes shape-stable.
2. Plain neutral grey surface: Great for lamination with decorative paper, fabric or printed face paper.
3. Cost-effective rigid substrate: Reliable stiffness at a competitive price for backing and structural packaging.
