Key Features
Superior Structural Performance
Available in grammages ranging from 250gsm to 450gsm (customizable), the board offers excellent rigidity and load-bearing capacity. Its tight fiber structure resists warping and creasing, ensuring boxes maintain their shape during storage, transportation, and use.
Optimal Whiteness & Printability
Boasting a bright, uniform white surface (ISO brightness: 85-92%), the board provides a clean base for offset printing, digital printing, screen printing, or hot stamping. It absorbs inks evenly without bleeding, reproducing colors vividly and enhancing the visual appeal of branded packaging.
Eco-Friendly & Safe
Manufactured with FSC-certified pulp (optional), the board is 100% recyclable and free from harmful chemicals (e.g., heavy metals, formaldehyde). It meets food contact safety standards (FDA, EU 10/2011), making it suitable for food, cosmetic, and pharmaceutical packaging.
Consistent Quality & Versatility
Strict quality control ensures consistent thickness, density, and surface smoothness across batches. It is compatible with various box structures-including folding cartons, rigid boxes, gift boxes, and shipping boxes-adapting to die-cutting, gluing, and folding processes seamlessly.
