Wood is used in wine packaging because the physical properties of wood include density, moisture content, shrinkage and expansion, and odor. The wood of the wine packaging box has different voids due to different water content and density. The high density is called heavy material, and its strength is high, the deformation is large, the nail holding force is also large, and the nail is easy to crack when nailed; the density is small. It is called light material, its strength is low, its deformation is small, its nail holding power is also small, and it is easy to crack when nails are nailed. The moisture content of the wine packaging box directly affects the strength of the wood. If it is too high, it will reduce its bending and tensile properties. The wine packaging box generally uses wood with a water content of 20% to the left. The shrinkage, expansion and flammability of wood are the three major shortcomings of wood, especially as packaging materials for wine packaging. After long-distance transportation, the temperature changes greatly, or because the storage warehouse has different humidity, it will cause the box and strip of the wood container. The board undergoes different degrees of contraction or expansion. The wine box wood also contains a special smell of resin, gum, volatile oil, tannin and other ingredients. When using the box, consider the smell of wood. Such as pine, cedar, eucalyptus, etc. should not be used as tea boxes, honey buckets, candy boxes, so as not to stain the turpentine or camphor smell; while using wood to hold wine, the included tannins can increase the taste of the wine .
