Three ply corrugated box has a minimum thickness of 3 mm. It is used in the packing of lightweight products. These types of boxes are used to pack products like toys, jewelry, edible oil, water bottles, pizza and etc. It is also known as a double wall box. Corrugated layers are made with high-end technology called fluting. Fluting fills the sheets with ridges that are sandwiched between two layers of cardboard making them resistant to a great deal of weight and pressure. When you use corrugated boxes for packaging you can be assured that any fragile object you have packed is given the safest cushioning in transit and handling. It is a perfect packaging box type for electronics, glassware, porcelain and other fragile materials.
