Abstract: Provided are a matting polymer composition having excellent weather resistance and impact resistance, and a matte sheet including the same. The matting polymer composition according to the present disclosure includes two kinds of styrene-acrylonitrile copolymers having different acrylonitrile contents, and a matting agent, and thus, a molded article manufactured by an extrusion or injection process has mechanical properties such as excellent weather resistance and impact resistance, and also may show an effective matting effect and excellent appearance quality.

Abstract: The present disclosure relates to a matting agent including polymer particles, a matting polymer composition including a matting agent, and a method of producing polymer particles. The polymer particles may be produced by a simple process using a suspension polymerization method, and is relatively easy to control a degree of crosslinking. In addition, in a case where a matting polymer composition is prepared using a matting agent including the polymer particles, it is possible to manufacture a molded article having excellent appearance and matting effect without deterioration of the existing mechanical properties such as impact strength and tensile strength of a thermoplastic polymer, and in particular, an excellent matting effect may be exerted even in the extrusion processing, which has been difficult to achieve in the related art.

Abstract: A large capacity welding wire container for storing welding wire, in which an outer shell, an inner shell, a base plate and upper and lower fixtures are mostly made of paper as well as application of steel is minimized so that the container is readily discarded after exhaustion and coupled/disassembled, and a welding wire package using the same. The welding wire container comprises: an upper protrusion enlarged in diameter beyond the outer shell for structurally reinforcing an upper outer portion of the outer shell; a lid sized for covering the outer shell; and an upper fixture for fixing and wrapping the lid at an upper end of the outer shell to obtain structural reinforcement, wherein the upper fixture includes a flange extending inward along an outer edge of the lid, a supporting face folded from the flange and extending along an outer periphery of the upper protrusion and a folded groove arranged under the supporting face and having a diameter smaller than that of the upper protrusion.
