The main load-bearing wood of the packing box is not allowed to have dead joints and missing joints that affect the strength, and allow to have joints that do not affect the strength. The size of the joints shall not exceed 40% of the width of the material, and the number of joints per meter of material length shall not be allowed. More than 5 (the joint size less than 10mm is not counted).
The main bearing wood of the packing box is not allowed to have cracks affecting the strength, and cracks with a width not exceeding 2mm are allowed, and the length of the cracks shall not exceed 1/4 of the length of the material, and the depth of the cracks shall not exceed 1/4 of the thickness of the material. There are several cracks on the surface and the cracks are not penetrated, so they should be calculated separately.
The main bearing wood of the packing box is not allowed to rot that affects the strength, the rotten area shall not exceed 30% of the width of the material, and the depth of decay shall not exceed 20% of the thickness of the material. But it is the best choice.
