Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the subject powder formed product, capable of preventing environmental pollution and excellent even in dispersibility by packaging a cracked powder formed product with a film. SOLUTION: This packaged powder formed product is obtained by packaging a powder formed product, in which many powder particles of an inorganic pigment, e.g. carbon black or an organic pigment, e.g. Madder Lake are aggregated to form a prescribed shape and the density thereof is 1.2-6 times based on the bulk density of the raw material powder with a film (e.g. an ethylene/ vinyl acetate copolymer) so as not to substantially leave a space between the formed product and the film and subsequently cracking the formed product by a physical force, e.g. vibration or pressurizing. In the form, the dispersion thereof into a vehicle can be improved and the bulking can be reduced even as compared with those of the powder which is the raw material.
