PROBLEM TO BE SOLVED: To provide the subject compsn. having excellent slipperiness and transparency, moreover capable of preventing the occurrence of a resin-tailing deposit (eye mucus called in a Japanese job-site jargon) to a dice on molding, by making a resin contain a slipping agent of glass grinds having an average particle dia. in a specified range. SOLUTION: A slippery resin compsn. is obtained by adding 0.01-1.0 wt.% of a slipping agent of glass grinds having an average particle dia. of 0.1-200μm to such a resin as polyethylene terephthalate, polypropylene, low-density polyethylene, or high-density polyethylene resins. A mixing method may be a method of using a mixing apparatus such as a mixing roll, a Banbury mixer, an extruder, a Henschel mixer, or the like, and also a method of forming previously a master batch of a resin of a small amt. and a glass grinds, then blending this to the intended resin. The glass is not limited particularly in the kind and is used of oxide glass, fluoride glass, silicate glass, etc.
