[0002] Paper corner protector is also called edge board, which is one of the most popular packaging products in the world, used to replace wood packaging and other heavy packaging methods. It has the characteristics of low price, light weight, firmness, environmental protection, etc. It is also known as paper corner protector or corner protector body, edge board, corner paper, paper angle steel, which is made of yarn tube paper and kraft paper by setting and pressing with a complete corner protector machine.
