What Is The Difference Between Packaging Plywood And Solid Wood?

The current wooden box packaging is mainly based on plywood or solid wood for packaging. The boxes of these two materials have their own characteristics. So what is the difference between using plywood packaging and solid wood packaging? What is the difference between solid wood.
1. Common plywood has three plywood, five plywood, nine plywood and twelve plywood. The quality of packaging plywood is much worse than that of solid wood.
2. The age of the wood of the solid wood board is different, and the density of the wood is different, so the coefficient of thermal expansion of the board is different and it is easy to deform, and it is easy to crack under the condition of dehydration. Because of its criss-cross structure, the layers are mutually restrained, and the deformation is very small. Compared with the multi-layer solid wood floor, the solid wood floor is more stable and not easy to deform.
3. The multi-layer solid wood board also needs to consider its load-bearing capacity for the ground and thermal conductivity for geothermal heat, while the general plywood does not have much consideration here.
