Cartons are classified by size into standard postal cartons and customer-customized specification cartons. Postal standard cartons are currently the most sold cartons online. From large to small, there are 12 types ranging from No. 1 to No. 12. It is not difficult to notice that standard cartons are all rectangular in shape. For special-sized products, such as keyboards and LCD monitors, which are flat items, Sellers usually choose to have cardboard box factories customize. Customization not only allows for custom specifications and sizes but also enables the printing of one's own logo on them, making it look very professional. Customization requires factory mold making and also incurs design and printing costs, so the starting price is generally high, usually starting at three to four hundred yuan.

There are various materials for cartons. Good materials not only have high hardness but also are light in weight, while inferior materials often have very low hardness and are prone to deformation. The materials of cartons on the market, from top to bottom, are "KK>KA>KB>AA>AB>BB". KK material is currently the best material, with a thickness of three layers sufficient to support the weight of a normal adult. Its surface is smooth and has a good texture.
