The invention provides a polyethylene resin foam sheet for cardboards, wherein the polyethylene resin foam sheet is excellent in buffer property and the glass is not easy to slide. The polyethylene resin foam sheet for cardboards is characterized in that the thickness, the basis weight, the surface resistivity, the arithmetic mean of the surface roughness, the maximal height of the surface roughness and the average length of the contour unit of the surface roughness thereof are respectively 0.15-0.50 mm, 15-50 g/m2, 109-1013 omega, 25-50 mum, 120-250 mum, and 200-600 mum. The result of dividing the thickness by the maximal height of the surface roughness is 1.3-3. |
