Medium Liner Paper
Medium liner paper is the fluted layer between two liners in corrugated cardboard. The quality of the medium largely determines the stacking strength and crush resistance of the box, making it a critical component in the packaging industry.
- The core fluting layer of cardboard
- High ring crush for stacking strength
- Consistent grammage and strength
- Supports predictable cardboard performance
The role of medium in cardboard
The medium layer provides the fluted structure that resists bending and stacking pressure. Good ring crush lets the box withstand loads when stacked high in the warehouse and during shipping.
- Withstands stacking pressure
- Adds rigidity to the box walls
- Keeps the box shape stable
Consistent quality for production
We keep the grammage and strength of the medium consistent so that cardboard performance is predictable on our customers' production lines. This consistency is important for corrugator machine efficiency.
Frequently Asked Questions
What is ring crush in medium paper?
Ring crush is a measure of a paper's compressive strength when formed into a ring — an important indicator of cardboard stacking strength.
What is the difference between medium and liner?
Medium is the fluted layer in the middle, while the liner is the flat layer on the outside. Together they form corrugated cardboard.
