Kraft liner is the high-strength outer liner of corrugated board. It typically needs stronger pulp and more demanding wet-end control than testliner.

Typical inputs

  • Raw material: kraft pulp / recovered kraft; OCC blends for semi-kraft
  • Capacity: project-dependent
  • GSM: 125–300 g/m² typical
  • Width / speed: confirm per project

Process overview

Pulping / blending → cleaning & screening → headbox → wire → press → dryer → size press (often) → calender → reel → rewinder.

Used / New / Mixed

Many kraft liner projects work well as a mixed solution: proven wet end plus renewed drives and controls.

What changes the price

Pulp preparation, size press, dryer capacity, calender type, and the level of process control.

Buyer checklist

  • Kraft vs semi-kraft target
