[Problem] This invention provides a mixture of PLA and CNC that retains the biodegradability inherent in PLA while improving its general-purpose properties without increasing environmental impact. [Solution] The PLA and CNC mixture of this invention is as follows: CNC with a crystallinity of 90% or higher and no chemical modification, consisting only of biodegradable substances, is added to PLA. The CNC dispersed in PLA becomes crystal nuclei, forming numerous crystals, thus forming ligands that span multiple crystals, creating a PLA crystal network structure. This structure improves the physical properties of PLA. The improvement is not achieved by cross-linking or polymerizing PLA into environmentally burdensome substances or other chemical substances, nor by adding environmentally burdensome chemicals. Instead, it is achieved by modifying the crystallinity and crystal structure of PLA by adding biodegradable, non-toxic, and environmentally unburdensome CNC. Therefore, this mixture of PLA and CNC improves the physical properties while maintaining the biodegradability inherent in PLA.
