摘要：PURPOSE: To increase the cushioning property, heat insulation property and hot insulation property by overlapping or meshing with a continuous layer on which a corrugation is applied, and at the same time, forming an air layer (chamber) between the layers. CONSTITUTION: Flutes 2, 3 which large and small corrugations of different pitches are overlapped or mesh with on one surface of a surface liner 1, so that a double layer packaging material X with corrugation on one surface is constituted. Preferably, for the forming of the double layers, B flute 3 with a large corrugation is overlapped or meshed with the top of A flute 2 with a small corrugation, and the ridge of the half corrugation of the B flute 3 with the large corrugation wraps of includes at least one ridge of the half corrugation of the A flute 2 with the small corrugation. In this case, the overlapping or meshing with the flutes 2, 3 can be manufactured by repeating a corrugating process by a publicly known one surface corrugated fiberboard manufacturing machine while changing the corrugation pitches.
