Abstract: Provided is a material suitable for producing a glass fiber-reinforced molded body with reduced generation of white haze while reducing the amount of a dispersing agent to be used. A glass fiber-reinforced propylene-based resin composition, including 10 to 50 parts by mass of glass fibers; 50 to 90 parts by mass of a propylene-based resin (provided that the both in total is 100 parts by mass); 0.3 parts by mass or more of carbon black; and a polyolefin wax having an average particle size of 1 to 40 ?m in an amount such that a mass ratio of the polyolefin wax to the carbon black is 0.75 to 1.5.

Abstract: A returnable framework structure for freight transportation capable of be assembled and disassembled in a simple manner. The structures are provided with sufficient structural strength, and are stable when disassembled structures are stacked. A plurality of frame elements are assembled on a rectangular skid, which forms the bottom surface of the structure, along the edges of the skid. An L-shaped corner guide is secured to each corner area of the skid, and the frames are fixed to the corner guides by screw members. On the upper corners of each frame, L-shaped corner guides are secured. The corner guides are secured to the other frames by screw members. The corner guides are secured to the skid in the direction perpendicular to the direction they are secured to the frame.
