Core plies number, strength and production cost of plywood in China
- The number of plywood layers will increase by 2 for every 3mm increase in plywood thickness;
- Plywood with the same thickness has higher strength with more layers; For example, the strength of 15 layers of 18mm plywood is greater than that of 13 layers of 18mm plywood;
- For plywood of the same thickness, the more layers, the higher the price; For example, the price of 7 layers of 6.5mm plywood is higher than that of 5 layers of 6.5mm plywood. Reason: The more layers, the more glue is used, and the higher labor and production costs are, so the higher the price is.
In general, the more layers of plywood with the same thickness, the better the quality.
