Technical

The pressure strength of paper honeycomb is depending on 3 basic values:

1. The cell size

How smaller the cell size, how higher the pressure resistance will be. The most common cell sizes are 10, 15, 20, 25 and 40 mm.

2. The paper grammage/quality

The honeycomb is made of 100% recycled paper.The most common grammage is 140, 170 and 200 gram/m2. The higher the paper grammage, the higher the pressure strength will be.

3. The moisture content

During the production process of paper honeycomb the paper will reach a moisture content of about 14% (8% of the paper and 6% of the glue). If the honeycomb is not dried with an expander/dryer the pressure strength will be about 50% lower.The highest pressure strength will be at 3% moisture content. When the dried honeycomb is placed in an area with a humidity of 70% the paper will absorb the moisture and after 30 minutes the paper honeycomb will have a moisture content of 8%.
