PROBLEM TO BE SOLVED: To provide a polyolefin resin foam having a very low possibility of contaminating the surface of a partner to be contacted when used as a packaging material, excellent appearance, and uniform antistatic properties over the entire surface. An object of the present invention is to provide a production method of the above and a polyolefin resin foam. SOLUTION: The method for producing a polyolefin resin foam of the present invention is a high crystallization temperature of 110 ° C. or lower, a melt temperature at a measurement temperature of 190 ° C. and a shear rate of 100 sec −1 of 80 to 1000 Pa · s. A molecular type antistatic agent, a polyolefin resin and a physical foaming agent are kneaded in an extruder to form a foamable polyolefin resin melt, and the foamable polyolefin resin melt is extruded and foamed. A production method for obtaining a polyolefin resin foam, wherein 2 to 8 parts by weight of the polymer type antistatic agent is added to 100 parts by weight of a polyolefin resin, and the apparent density of the foam is 65 g / L or less. Extrude foam to become. [Selection] Figure 1 |
