In recent years, paper packaging containers have been welcomed by consumers because of their advantages such as low cost, resource saving, good mechanical processing performance, large-scale mechanized production, easy printing, harmless and non-toxic in use, and easy recycling. Moreover, because they conform to the concept of green and environmental protection, paper products packaging ranks first in the use of packaging materials. However, in the process of the continuous development of paper packaging, people have also found the shortcomings of paper packaging, such as poor load-bearing capacity of carton packaging, easy deformation and so on. In the face of these problems encountered in the development, paper protection has gradually emerged in paper packaging, especially in honeycomb carton packaging and corrugated carton packaging. In the whole development process, the paper corner protector also began to change its previous shape, and there were surrounding corner protector, bending corner protector and U-shaped corner protector.
In honeycomb carton packaging, first use honeycomb cardboard to make the box into a complete box, and then use paper corner to reinforce it. The combination of paper corner protector and honeycomb paperboard not only enhances the compression resistance of honeycomb carton, greatly enhances the bearing capacity of honeycomb carton, but also improves the aesthetic performance of honeycomb carton, making the appearance of honeycomb carton more perfect. After the appearance of paper corner protection, the disadvantages of corrugated box such as poor load-bearing capacity and easy deformation have also been significantly improved.
For a long time, the shape and use of paper corner guards have not changed. They are only straight strips used as edge guards for cartons. However, with the increasing demand for paper corner protection, the scope of its use is also expanding. For example, it has developed from being used as the edge protection of cartons to being used as the edge protection of barrel shaped objects such as steel coils. As another form of paper corner protection, the use of U-shaped corner protection is also increasing. Today, U-shaped corner guards are mainly used in the production of paper trays. Compared with V-shaped corner guards, U-shaped corner guards have great advantages. The use of U-shaped corner protector on the paper tray can increase the bearing capacity of the paper tray, facilitate the processing and production of the paper tray, and improve the efficiency of the production of the paper tray.
Since paper corner guards can bind products together to make the overall packaging more solid and firm, fix the goods on the pallet to protect the products and their edges, protect and support the products during the handling process and can be customized according to different specifications and requirements of customers, they are more and more widely used in product packaging. At present, there are also some manufacturers producing paper angle protection and paper angle protection production lines in China. Shanghai Lvshun Packaging Machinery Co., Ltd. is one of the earliest manufacturers specializing in producing paper angle protection production lines, paper cutting machines, paper angle protection and other packaging materials in China. According to market needs, the company has developed a complete set of paper angle protection production lines and paper cutting machines with novel design, excellent manufacturing, simple operation, complete functions and reasonable prices, It is welcomed and supported by the majority of users.
