Traditional paper machines typically have only one forming wire, on which the pulp is dewatered to form a single sheet of paper. A “three layer” machine, however, has three independent forming wires.

1. Top forming wire: Forms the top layer of the cardboard.

2. Middle forming wire: Forms the middle layer of the cardboard.

3. Bottom forming wire: Forms the bottom layer of the cardboard.

Three Layer Corrugated Paper Machine Final Products

1. High-grade linerboard: Used for manufacturing the face and linerboard of heavy-duty corrugated boxes.

2. Linerboard: Often referred to as “kraft linerboard,” this product uses high-quality virgin wood pulp for the surface, while the middle and bottom layers may use recycled pulp, ensuring surface strength and printability while controlling costs.

3. High-strength corrugated base paper: Although less common, it can be used to produce very high basis weight corrugated core paper.

4. Specialty industrial paperboard: Industrial padding paperboard requiring high thickness and high strength.
