Corrugated cardboard internal reinforcement structure for packing box

摘要

The present invention relates to a corrugated cardboard inner reinforcing structure, and is particularly inserted into the inner and outer spaces formed in the corrugated cardboard for packaging boxes to minimize the change in the shape of the corrugated cardboard itself during the actual use, as well as In order to alleviate the impact from the outside, the inner and outer reinforcement interlinings provided to be inserted are arranged in a predetermined interval, and inserted, but a certain portion of the reinforcement is formed so as to form several reinforcement cores tightly close to each other, the packaging box By making it possible to greatly improve the durability and robustness of the corrugated cardboard itself, it was able to effectively buffer and mitigate even when a strong external impact was applied during actual use, and also to store and store a somewhat heavy load. The door that the packing box sinks because the load cannot be overcome In addition, it is possible to prevent the product from being damaged, and furthermore, even when faced with wet weather conditions such as rainy weather, it is possible to prevent the box from decaying and deforming due to moisture, thereby effectively protecting the packaged goods. It is designed to protect and improve the quality of the packaging.
