This research investigated the effect of foam cushioning from potato starch by the extruder screw single aimed to study the effects of Inputs include the moisture content of the material.The rate of expansion, density, water solubility index wage compression stress strain and modulus from the study, it was found that the moisture content influence the properties of the foam cushioning, potato starch By.The rate will result in swelling, density, water solubility index, labor and decreased but the stresses and stress strength increasing.
