The present invention belongs to the field of biopolymer material processing technology, and discloses a PLA/PCL two-phase biopolymer composite material and its preparation method, as well as PLA/PCL products. The composite material comprises a core and a shell wrapped around the core, wherein the core is PLA, the shell is PCL, and the diameter of the core is 0.8-2.8 μ m, and the diameter of the shell is 2.7-7 μ m. This preparation method overcomes the defect problem of material molecular chain breakage and degradation caused by the existing melt blending equipment mainly based on the shear deformation principle of single and double screw extruders. In addition, the PLA/PCL two-phase biopolymer composite material has a core-shell structure and excellent tensile properties and flexibility.
