What is reinforced cardboard?

About one-third the weight of wood! Introducing cardboard with strength comparable to that of wood.

Let me introduce the differences between reinforced cardboard and regular cardboard. Regular cardboard is made with a single layer of fluted material, known as the flute, which is the wavy part between the front and back surfaces of the cardboard. On the other hand, reinforced cardboard is made with 2 or 3 layers of flutes, and the paper used as raw material is thicker, harder, and has very high strength. 2-layer reinforced cardboard is called "double wall," while 3-layer reinforced cardboard is referred to as "triple wall," allowing for strength to be adjusted according to the packaging items. 【Features of Reinforced Cardboard】 ■ Weighs about one-third of wood ■ Made with 2 or 3 layers of flutes ■ Strength can be adjusted according to the packaging items *For more details, please refer to the PDF document or feel free to contact us.
