Description

Technical Field

[0001] This utility model belongs to the field of paper corner protector technology, specifically a triangular paper corner protector. Background Technology

[0002] Triangular paper corner protectors are long, strip-shaped protective products made of paper as the base material and pressed into a triangular cross-section. They are mainly used in the packaging field. By wrapping the corners of goods, they can cushion impacts, enhance the strength of the corners, and prevent damage to the corners due to squeezing or collisions during transportation or storage. They are also environmentally friendly, recyclable, and low-cost.

[0003] In practical applications, when the size of the goods exceeds the length of a single set of paper corner protectors, it is necessary to splice two or more sets of paper corner protectors together. However, there are obvious drawbacks: due to the lack of a dedicated splicing structure, the splicing points of two sets of paper corner protectors are simply stacked or fixed with tape. The overall stability after splicing is poor, and it is easy to misalign or separate under stress, which greatly reduces the protective effect. Utility Model Content
