250g Color Metallic Cardstock for Art Projects
White Cardboard (Ivory Board) is a premium, high-bulk packaging board manufactured exclusively from 100% virgin wood pulp. Unlike standard Duplex Board, this material features consistent whiteness on both top and bottom surfaces, including the core. The multi-layer construction combines bleached chemical pulp on exterior surfaces with mechanical pulp in the middle layer, delivering exceptional bulk and stiffness. This makes it the preferred choice for applications demanding superior hygiene, structural strength, and premium aesthetics.
Key Material Advantages
- Pure Virgin Pulp: Contains zero recycled waste paper, ensuring maximum hygiene standards and eliminating any odor concerns
- Double-Sided Whiteness: Even with single-sided coating, the reverse side maintains inherent whiteness, providing clean, sanitary appearance for box interiors
- High Bulk Volume: Superior thickness and stiffness compared to other boards of equivalent weight, offering excellent stiffness-to-weight ratio
- Premium Surface Quality: Clay-coated surface ensures ultra-smooth finish ideal for high-resolution printing techniques including Offset, UV, Embossing, and Hot Stamping
