Provided are a method for producing pellets that are easy to be uniformly molded at the time of using the pellet for molding even when the pellets include a large amount of inorganic substance particles, the pellets, and a method for molding a resin molded article. The method for producing pellets according to the present invention includes a method for producing pellets formed from a resin composition including a crystalline macromolecule and an inorganic fine powder or organic fine powder in a mass ratio of 50:50 to 20:80, the method including the step of kneading the crystalline macromolecule and the inorganic fine powder or the organic fine powder so that the microcrystalline size of the crystalline macromolecule is 190 Å or smaller. The pellets according to the present invention are pellets formed from a resin composition including a crystalline macromolecule having a microcrystalline size of 190 Å or smaller, and inorganic substance particles in a mass ratio of 50:50 to 20:80.

Method for producing pellets, method for producing resin molded article, and pellets

Provided is a sheet not generating feeding failure in a device having a heat setting process even when a large amount of an inorganic filler is included and a thermoplastic resin composition for forming the sheet. The thermoplastic resin composition may include at least a thermoplastic resin and an inorganic filler, in which the thermoplastic resin includes polypropylene having no long chain branch (B) and polypropylene having a long chain branching structure (A) in a mass ratio of 80:20 to 98:2.
