Ivory board, also known as white cardboard, is a premium-grade paperboard manufactured by laminating multiple high-quality bleached chemical pulp sheets. It is characterized by:
- High Stiffness & Smoothness
- Surface brightness exceeds 92% (CIE standard), providing superior printability.
- Burr-free edges ensure precision in high-end packaging.
- Low Weight Variability
- Basis weight ranges from 150–400 g/m², balancing durability and flexibility.
- Eco-Friendly Composition
- Uses 100% virgin pulp, meeting food-grade safety standards for cosmetics and pharmaceutical packaging.
Core Applications of Ivory Board
Ivory board’s versatility supports diverse industries:
- Premium Packaging
- Cosmetic boxes, medicine cases, and luxury gift boxes (e.g., Mid-Autumn Festival packaging).
- Printing Products
- Business cards, invitations, certificates, and calendars due to its ink-absorbent surface.
- Commercial Labels
- High-gloss finish ideal for brand tags and promotional materials.
Market Insight: In 2024, China’s ivory board market faced oversupply pressures, yet demand for high-value rolls remained stable in sectors like premium printing.
