Background
Along with the national policy requirement for green package development, express enterprises continuously develop a series of green package products, and the requirement for product package is reduced for secondary package. On the basis of traditional package protection, the whole fragile product generally has protection requirements for reinforcing the package, and the edges and corners of the packaging box are generally reinforced and designed in the form of edge protection and corner protection so as to protect the appearance of the product and support the product. At present, the main materials of the edge protection and the corner protection in the market mainly comprise corrugated paper, pearl cotton, polypropylene, polyethylene and the like. The protection edge is mainly in an L-shaped and U-shaped structure, the protection angles are mainly in the form of three-face protection angles and four-face wrap angles, the four-face wrap angles are mainly used for angle protection of flat products, and the protection of the whole box of express products is mainly in the form of three-face protection angles.
With the promulgation and implementation of national plastic banning, the traditional three-sided corner protectors made of plastic materials such as pearl wool, polypropylene, polyethylene and the like are also at risk of being replaced gradually. The paper corner protector is more environment-friendly due to the fact that the paper corner protector is made of materials, the production process is simple, and the paper corner protector is a key object for developing the future environment-friendly corner protector. However, the traditional paper corner protector has two main problems, namely, the bottom or side structure of the traditional corrugated paper corner protector is relatively thin, and the shock resistance is poor; secondly, the traditional honeycomb paper corner protector generally adopts an adhesive to bond and fix the three-sided paper board, and the bonding part is easy to crack under special environment.
