Super-Filled Paper Sheets

Cellulose-Reinforced, High Filler Content Products


FPInnovations has developed a new method to prepare furnishes for super-filled paper and paperboard sheets, having mineral filler content up to 90% by weight. Using this method, super-filled sheets can be fabricated using existing, conventional equipment, producing sheets with basis weights half those of commercially available plastic-based stone paper sheets at equal filler content, while having higher opacity, brightness, tensile strength, and stiffness.

By incorporating cellulosic fibrils with a binder into the furnish, low cost super-filled sheets can be produced from renewable, recyclable, biodegradable, and sustainable materials.
