Three Common Finishes for Plywood

Regarding plywood Finishes, we may often hear processes such as direct pasting, pasting, and multi-layer encryption, but what do they mean? Which of them works best?

Let’s talk about the three common finishes of plywood: direct sticking, double sticking, and multi-layer encryption.

Direct application is to apply the facing paper directly to the plywood substrate.

For re-adhesion, the decorative paper and texture are pressed on the technical veneer with a steel plate, and then the technical veneer is pressed onto the plywood base material.

In the early days, everyone used direct stickers, but direct stickers have high requirements on the flatness of the substrate. If you are not careful, defective products will appear, and the yield rate is low. Therefore, there was the emergence of the re-adhesive process later. Because the re-adhesive process divides the veneer process into two steps, the pressing time is reduced and the temperature is lowered. Therefore, the overall yield rate is much higher than that of the direct paste.

Finally, let’s talk about multi-layer encryption. Multi-layer encryption is a new process that has emerged in recent years. It is a plywood substrate with an ultra-thin MDF attached. At present, the more common encryption methods are 16+1+1, 14+2+2, 17+1, etc. 16+1+1 means adding a 1mm density board on both sides of the 16mm substrate, and 17+1 is single-sided encryption.

Direct sticking has high requirements on the flatness of the plywood base material, and the flatness of the encrypted plywood base material will be greatly enhanced, no matter the next direct sticking or double sticking, it is easy to handle.

However, after all, multi-layer encryption is to paste a density board on the base material, so the overall environmental protection performance of the plywood will be reduced.
