摘要： PROBLEM TO BE SOLVED: To produce a low-density molded product and a low-density sheet which are excellent in cushioning properties and are both useful as cushioning materials for packaging by using pulp fibers. SOLUTION: Finely fibrillated pulp with a water retention value of 210-450% is used in an amount of 3-65wt.% and curled fibers with a water retention value of 25-65wt.% and a wet curl factor of 0.5-1.0 in an amount of 35-97wt.% based on the whole fiber weight are mixed to prepare an aqueous slurry. Then, the slurry is cast in a mold provided with a mesh, molded by draining and dried to give a molded product. Further, the water slurry of this mixture is made into a sheet with a wet type paper-making machine and the sheet is dried to give the objective sheet.

摘要： PURPOSE: To receive the weight of a product under the condition that the product is prevented from being damaged, and safely pack the product by absorbing vibration by a method wherein thermoplastic synthetic resin is hardened under the condition that fiber stock, the thermoplastic synthetic resin in which is melted and which is compressed so as to have the density in response to the gap of molds. CONSTITUTION: After the thermoplastic synthetic resin containing fiber stock 11 obtained in waste paper material is heated so as to melt the thermoplastic synthetic resin, the fiber stock 11 is fed between molds 13 and 15 and the melted thermoplastic synthetic resin is hardened under pressure so as to mold a paper packing material 1. Under the condition that the gap t1 between the molds 13 and 15 in response to an upright wall 5 and a flange part 7 is set to be narrower than the gap t2 between the molds 13 and 15 in response to a housing recessed part 9, the thermoplastic synthetic resin, paper fibers and threads in response to the upright wall 5 and the flange part 7 are turned to have high density and high strength due to high pressurizing force. Thus, the product housed in the housing recessed part 9 can be surely received and, at the same time, the external force such as vibration applying at transport or the like can efficiently be absorbed.
