The invention relates to PVA foaming resin suitable for simple foaming equipment and a preparation method of the PVA foaming resin. The PVA foaming resin comprises the following components in parts by weight: 10-80 parts of PVA; 0 to 80 parts of starch; 5-40 parts of an environment-friendly plasticizer; 0.1 to 4 parts of a compatilizer; 0.5 to 10 parts of a foaming agent; 0.5 to 8 parts of a nucleating agent; 0.2 to 3 parts of a lubricant; and 0.2 to 2 parts of an antioxidant. The PVA foaming resin disclosed by the invention is simple in foaming process and low in equipment investment; the foaming device can be used for foaming in a small and simple foaming device, and can be used for various cushion packages. According to the invention, the problems of high transportation cost and small sales radius of the foaming buffer filling material can be perfectly solved; the PVA foaming resin can be completely biodegraded, can be subjected to subsequent treatment in a water dissolving manner after being discarded, ca
