Key Differences Between Grey Board and Kappa Board
| Feature | Grey Board | Kappa Board |
|---|---|---|
| Composition | Made from recycled paper pulp, often with a grey core due to unbleached fibers. | Made from virgin kraft pulp, providing a cleaner, more uniform appearance. |
| Color | Typically grey or brown due to recycled content. | Bright white or off-white, offering better print clarity. |
| Strength | Good rigidity but may vary based on recycled content. | Higher tensile strength and consistency due to pure kraft fibers. |
| Surface Finish | Slightly rougher texture, may require coating for high-end prints. | Smoother surface, ideal for fine printing and laminations. |
| Cost | Generally more economical due to recycled materials. | More expensive because of premium virgin pulp. |
| Applications | Best for cost-effective packaging, bookbinding, and structural inserts. | Preferred for high-end packaging, luxury branding, and detailed graphic work. |
Which One Should You Choose?
Choose Grey Board if you need an affordable, eco-friendly option for sturdy packaging or bookbinding where print quality is not the highest priority.
Choose Kappa Board if you require superior printability, a smoother finish, and higher durability for premium packaging, displays, or branding materials.
Both materials have their strengths, and the right choice depends on your project's budget, sustainability goals, and aesthetic requirements. Whether you opt for the cost-effective Grey Board or the high-end Kappa Board, both deliver reliable performance in their respective applications.
