What is Clay Coated Kraft Back (CCK) Paperboard?
Clay Coated Kraft Back (CCK) paperboard is a versatile, recyclable packaging material that combines a white clay-coated front with a natural brown kraft back. The clay coating provides a smooth, printable surface ideal for high-quality graphics, while the kraft back ensures strength and moisture resistance. This dual-sided design makes CCK a popular choice for gift boxes, retail packaging, and food-safe applications.
Manufactured using the Kraft process, CCK starts with renewable wood fibers, which are processed and coated with a thin layer of clay to enhance printability. Available in single-sided (clay front, kraft back) or double-coated (clay on both sides) variants, CCK balances sustainability with aesthetic appeal.

How to Choose CCK for Gift Packaging
Selecting the right CCK variant ensures your gift boxes meet both functional and aesthetic goals. Consider these factors:
- Single vs. Double Coated: Single-sided CCK (white front, kraft back) offers a classic look, while double-coated (white both sides) suits a premium, uniform finish.
- Weight & Thickness: Use 14–16 pt for lightweight to medium boxes; opt for 24–28 pt for rigid or luxury sets requiring added durability.
- Finish Options: Choose matte for an elegant, non-reflective surface or semi-gloss for enhanced brightness and print clarity.
- Sustainability: Prioritize FSC-certified or high recycled-content options for eco-friendly packaging.
For best results, align the thickness with your gift’s weight and the unboxing experience you want to create.
