Resin composition and molded article containing the same

Abstract

The present invention provides a resin composition and a molded article containing the same, which exhibits excellent moldability for various molded articles, including thin films, even when using cellulose powder with a relatively large average particle size, and enables the production of highly practical molded articles. [Solution] The resin composition is a resin composition containing cellulose powder, wherein the 50% particle size D50 of the cellulose powder is 10 μm or more and 36 μm or less, and satisfies at least one of the following conditions [Condition 1] and [Condition 2]. [Condition 1] The 90% particle size D90 of the cellulose powder is 75 μm or less. [Condition 2] The value obtained by dividing the difference between the 90% particle size D90 and the 10% particle size D10 of the cellulose powder by D50, (D90-D10) / D50, is 2.45 or less.

Claims
