WIPO Patent Application WO/2024/080233

A1

To provide technology capable of producing a packing material that contributes highly to the environment.　Provided is a packing material that contains a fibrous material containing waste paper and/or pulp, a binder, sodium bicarbonate, a surfactant, and a water-soluble softener, in which the binder contains one or more selected from polysaccharides and proteins. A urea derivative having a chemical structural formula of R1, R2-N-CO-N-R3, R4 (R1 to R4: H or a C1-4 saturated and/or unsaturated hydrocarbon group) can be used as the softener according to this technology. Also, a water-soluble C3-15 polyhydric alcohol can also be used as the softener used in the packing material according to this technology. In this case, a polyhydric alcohol in which the number of carbon atoms and number of hydroxyl (OH) groups in the molecular structure is number of hydroxyl groups
