美国一家公司研制成了一种可以再生的包装新垫材，以取代目前广泛使用的泡沫塑料垫材。这种新垫材是用旧报纸的再生纸浆和水制成的，其制法是：首先按不同包装物品的保护要求，通过电脑设计制成铝模，然后将纸浆灌入铝模内，将模中的水挤出，干燥后即成为固态垫材。试验结果表 A U.S. company has developed a new, renewable packaging mat to replace the currently widely used foam mat. The new mat is made of recycled paper pulp and water from old newspapers. The method is as follows: First, according to the protection requirements of different packages, the aluminum mold is made by computer design, then the pulp is poured into aluminum mold, The water in the mold is extruded and becomes a solid mat after drying.
