The packaging board includes solid wood board, MDF, plywood, veneer, etc., which is mainly used for the production of equipment, instruments, parts, etc.
Solid wood planks are planks made from intact timber (logs). Solid wood boards are generally classified according to the name of the board substance (log material), and there is no unified standard specification. Solid wood boards are relative to a large number of non-solid wood boards, such as plywood produced by using wood processing scraps, crop straw, chaff, peanut shell and other materials, pressing templates, etc.
Solid wood planks are durable, natural textures, most of them have the unique aroma of natural wood, have good moisture absorption and air permeability, are beneficial to human health, do not cause environmental pollution, and are high-quality boards for making high-end furniture and decorating houses. Solid wood panels made of special materials (e.g. beech) are also ideal for the manufacture of gun butts and precision instruments.
Due to the high cost of solid wood panels and the high requirements of construction technology, they are not used much in decoration. In addition, the limited availability of wood makes it impossible to use a large number of solid wood panels for furniture and house decoration. It is a wise choice to use low-cost, high-quality and easy-to-construct man-made plywood to decorate the house, and it can also be regarded as a due contribution to the protection of forest resources and the acceleration of the construction of ecological civilization.
Plywood is a three-layer or multi-layer plate-like material made of wood segments that are rotary cut into veneer or cut into thin wood by wood planer, and then glued together with adhesive, usually with odd layers of veneer, and the fiber direction of adjacent layers of veneer is glued perpendicular to each other.
Plywood is one of the commonly used materials for furniture, one of the three major wood-based panels, and can also be used for aircraft, ships, trains, automobiles, construction and packaging boxes. A group of veneers is usually glued perpendicular to each other in the direction of the wood grain of adjacent layers, and the surface and inner layers are usually symmetrically arranged on both sides of the central layer or core. It is made of a slab made of glued veneer criss-crossed in the direction of the wood grain, pressed under heated or unheated conditions. The number of layers is generally odd, and a few have even numbers. There is little difference in physical and mechanical properties in the vertical and horizontal directions. Commonly used types of plywood are plywood, plywood, etc. Plywood can improve the utilization rate of wood and is a major way to save wood.
