Straw fiber-material was prepared using mixture of particles and acerose straw fiber as raw material, mixture of polyvinyl alcohol (PVA), urea-formaldehyde resin (UF), and starch as bond, with two stages pressing and heating processes. The influence of molding technology on physical and mechanical properties of straw fiber-material was studied. Result showed that molding pressure, molding temperature and molding time in the first stage have great influence on compressive stress and cushioning propriety of the material; increasing molding pressure, temperature, and molding time can enhance the strength, but reduce the cushioning performance of the material; lacking of molding pressure and molding time can also reduce the strength of the material; the appropriate molding pressure is 40～50 kPa, molding temperature is 150～175 ℃, and molding time 6～10 min.
