Title:
CORRUGATED FIBERBOARD MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/200988
Kind Code:
A1
Abstract:
A corrugated fiberboard material (1) using a corrugated fiberboard in which a linerboard is adhered to a corrugating medium, wherein a measurement piece that has been cut out of the linerboard has a dynamic viscoelasticity within a prescribed range, as measured in a pulling/shearing mode with a temperature condition of 25 [°C] and a vibration condition of 100 [Hz] frequency. The dynamic viscoelasticity is defined by the value of the elastic modulus E' and the value of tanδ, which is the ratio of the loss modulus E'' to the elastic modulus E'. The prescribed range for the elastic modulus E' is 1.00×109 [Mpa] to 8.00×109 [Mpa], and the prescribed range for the tanδ is 2.50×10-2 to 1.50×10-1.
