The issue of the box's length, width, and height. Generally, for a three-layer box, the thickness is set around 3.5mm, while for a five-layer box, it's around 7mm. The box size design can be determined by first measuring the dimensions of the items to be stored, then adding the thickness of the box board. This yields the outer box dimensions. When customizing boxes, it's crucial to clearly inform the manufacturer whether you need the inner box or outer box dimensions.
