Double/Triple Wall refers to corrugated board structures consisting of two (double-wall) or three (triple-wall) layers of fluted medium combined with multiple liners. The stacked flute layers greatly enhance compression strength, puncture resistance, and load-bearing capability. This type of board is commonly used for heavy-duty applications such as industrial packaging, long-distance shipping, machinery protection, chemical products, and export cartons requiring high durability and strength. Double/triple wall corrugated board is essential for packaging heavy items and ensuring safe transport.
