[0002] In modern logistics and transportation, cartons, as a primary packaging material, play a crucial role in protecting products. During transportation, the corners of cartons are particularly susceptible to crushing and collisions, compromising the safety and integrity of products. Therefore, traditional cartons often fail to effectively address these challenges. This is why corner-reinforced cartons have emerged, designed to enhance their strength and impact resistance. This type of carton design incorporates reinforcements or structures at the four corners, significantly enhancing its resistance to pressure and impact. Corner-reinforced cartons not only improve packaging safety but also extend the carton's lifespan and reduce potential damage during transportation. This design is suitable for industries requiring high product protection, such as electronics, precision instruments, and fragile items. Using this technology, companies can improve logistics efficiency, reduce losses due to product damage, and ensure the safe arrival of products at their destinations.

[0003] However, after the items are packaged and stored in the corner-reinforced packaging carton, if the items stored inside the carton need to be transported and moved, the user needs to put his palm into the hole reserved inside the carton, and then lift the carton and the items stored inside it upwards. However, because the carton has poor toughness, it is easy to tear the carton during the lifting process. In addition, during the transportation and movement process, if foreign objects squeeze the carton, the carton itself has poor strength and toughness, so it is easy to be squeezed by foreign objects and deformed and damaged.
