Paperboard Grades and When to Use Them

  • SBS (Solid Bleached Sulfate): Bright, white board ideal for high-impact graphics, embossing, and food packaging.
  • SUS (Solid Unbleached Sulfate): Natural kraft fiber board designed for heavy loads and multipacks.
  • CRB (Coated Recycled Board): Recycled fiber content with reliable printability, widely used for food and consumer goods.
  • FBB (Folding Box Board): Multi-ply construction that is light but strong, offering sustainability and luxury print potential.
  • URB (Uncoated Recycled Board): Chipboard option for rigid structures where folding is not required.
  • Micro-Flute: Thin corrugated board with direct print capability, offering strength for large cartons and displays.

Paperboard That Runs & Finishes Well

Each grade pairs differently with print and finishing. Choose right to avoid waste and keep cartons sharp on shelf.

  • Teams needing embossing, foil, or sharp graphics → SBS
  • Heavy multipacks that require coatings and stiffness → SUS
  • High-volume CPG runs seeking cost efficiency → CRB
  • Luxury packs using soft-touch or foil finishes → FBB
  • Large or fragile cartons and displays needing rigidity → Micro-Flute
