Problems solved by technology

[0003] The above usage has the following problems in operation: it is not convenient to use, and it is not easy to break the plastic wrap on the rack of the carton, especially for the plastic wrap with large stretchability; The problem of not being able to withstand repeated tossing and repeated use is that the carton can only be used once for about 30 meters before being discarded and useless, which is not conducive to environmental protection and resource recycling; in addition, the tip of the teeth exposed outside the packaging is also easy to cause scratches. And there are certain safety hazards for children
