The progress in the process and modification of PLA is discussed, and the requirement for the property of PLA for molding, extrusion fdature, blowing film is mentioned.
The results showed that the use of the analytical method can be as the instruction for the reasonable selection of process parameter in the blowing from the extrusion profile.
