description PROBLEM TO BE SOLVED: To provide a cushioning material which is excellent in elastic performance at a low cost by using a molded article which consists of a mixture of a paper component and a binder containing a specified amount of gelatin or alginic acid. SOLUTION: A molded article which is used as a cushioning material for the packaging of household electric appliances, precise equipment and OA equipment, etc., is formed by mixing a paper component and a binder which contains 50wt.% or higher of gelatin or alginic acid, and preferably, the molded article is made into a foaming molded article for which the paper component and the binder containing 50wt.% or higher of gelatin or alginic acid, and before foaming, a crosslinking reaction promoter, and a softening agent are mixed. At this time, for the paper component, crushed or fiber-loosened old paper, is used, and for the binder, a natural substance is used. As the bridging reaction promoter, a crosslinking promoting enzyme, formalin, and acetaldehyde, etc., can be counted, and as the softening agent, glycerine, ethylene glycol, diethylene glycol and polyethylene glycol, etc., can be counted.
