The first point is that the carton has the function of protecting the goods. Of course, when making the carton, it must meet the requirements on the side pressure strength, burst strength, puncture strength, adhesive strength, and compressive strength of the empty box. Physical strength is required to achieve its protective function. The second is the sales function. The exquisite printing patterns on the carton can attract people's attention, evoke people's desire to buy, and can play a good role in publicity.

Moreover, the appearance of the carton is also very beautiful. In short, the material of the carton is light, which is good for protecting the product, and is very convenient for transportation. It also has an important pulling effect on sales.
