As the most popular board at present, multi-layer boards are mainly used in decoration and furniture production industries. So what are the issues that need to be paid attention to when selecting materials for multi-layer boards?

　　There is a difference between the front and back of the multilayer board. When selecting, the plywood should have clear wood grain, smooth and clean front, no roughness, and smooth and non-sluggish hand feeling. The multi-layer board should not have defects such as damage, bruises, bruises, scars, etc. The multilayer board has no degumming phenomenon. Some multi-layer boards are made by pasting two veneers with different textures together. Therefore, in the selection, attention should be paid to the tight joints of the plywood, and there is no unevenness.

　　When selecting multilayer boards, pay attention to choosing plywood that does not disperse glue. If the sound is brittle when knocking on each part of the plywood by hand, the quality is good. If the sound is dull, it means that the plywood has appeared loose glue.
