Abstract
Recently, paper cushioning has been used extensively for product protection. A molded pulp cushioning is one of the typical paper cushioning and eco-friendly materials. However, there are some technical issues for molded pulpcushioning to improve further. Unlike block form cushioning which design process is standardized(ｅｇ. expanded polystyrene, formed polyurethane), molded pulp cushioning which have thin wall structures and formed for each product haven't been standardized for the cushioning design method. The prediction of the
acceleration level during impact is difficult particularly. Additionally, ｉｔ ｍｉｇｈｔ ｂｅ ａ Pｒｏｂｌem ｔｈａｔ ｔｈｅ lｅａｄ ｔiｍｅ ｗｏｕｌｄ ｂｅ lｏｎｇ ｉｆ ａ ｍｏｌｄ ｔｏｏｌ ｎｅｅｄｓ ｔｏ ｂｅ ｆｉｘｅｄ ｏｆｔｅｎ.

It is feasibIe to predict the acceleratｉｏｎ ｌｅｖｅｌ ｂｙ ｕｓｉｎｇ ａ ｓｅｔ ｏｆ ｍｏｌｄｅｄ ｐｕｌp components which cushioning property is known. Furthermore, this mold tool would be able to adjust a number of products even in one tool because of the frexibility to change the position of components or the quantity of them in a base plate.
