Logo Folding Metallic Packaging Boxes Custom Gold Silver Cardboard

Premium White Cardboard Material
White Cardboard (Ivory Board) is a premium, high-bulk packaging
board manufactured exclusively from 100% virgin wood pulp. Unlike
Duplex Board, it 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 material is ideal for industries requiring
superior hygiene standards, structural strength, and premium
aesthetic appeal.
Key Material Advantages
- Pure Virgin Pulp: Contains zero recycled waste paper, ensuring maximum hygiene
standards and eliminating odors
- Double-Sided Whiteness: Even with single-sided coating, the reverse side maintains clean
white appearance for sanitary interior presentation
- High Bulk Volume: Superior thickness and stiffness compared to equivalent weight
boards, offering excellent stiffness-to-weight ratio
- Premium Surface Quality: Clay-coated surface provides exceptional smoothness for
high-resolution printing including Offset, UV, Embossing, and Hot
Stamping
