Experiments are conducted to study the effects of the forming process on the properties of high strength packaging materials made from waste corrugated containers. The results are as follows. With the same degree of beating, increase of the hotpressing pressure can improve the tensile strength, elongation at break, and modulus of elasticity; Increase of the hot- pressing temperature can only improve the tensile strength and modulus of elasticity. When the hot-pressing temperature is 165℃, beating degree is 35°SR and hot pressing pressure is 2 MPa, the elongation at break is the largest. And the peak of burst degree appears at the condition of 150℃, 27°SR, and 5 MPa. The higher the hot press temperature, the smaller the pressure and, the better the stiffness. The results also show that in order to save energy and shorten the preparation cycle, a better molding process scheme uses 27°SR beating degree and 165℃ hot-pressing temperature, while 5 MPa hot pressing drying or 0.08 MPa vacuum drying condition can be selected according to the specific demand.
