PROBLEM TO BE SOLVED: To provide a plastic molding with excellent combustibility imparted, which, by the addition of a very small amount of an organic acid aluminium having a specific carbon number, is made excellent in combustion efficiency, is not colored by the material itself, is not reduced in strength, and can be colored by the addition of a pigment depending on uses. SOLUTION: By incorporating in a plastic 0.005-1.0 wt.%, in terms of aluminum, of an organic acid aluminum having a carbon number in the range of 2-30, the combustibility of the plastic is improved. The plastic used may include polyolefins such as polyethylene and polypropylene. As the organic acid aluminum, the aluminum salt of 12-hydroxystearic acid shows particularly excellent effects.
