Thicker cardboard is suitable for packing light products and a serious shipping environment. Thinner material was ideal for packing heavy products with a proper shipping environment. For a single layer, B flute is the most practical flute. BE flute for double layer and ABB flute for the triple-layer (single/double/triple layer also being called single/double/triple wall)
