| Abstract: |
| The packaging characteristics of Poly(L-lactic acid) (PLLA) was reviewed, including mechanical, crystallization and gas barrier properties. The influence of molecular orientation, crystal habit, physical aging, blending, and multi-layer composite process of PLLA on its packaging characteristics was discussed. The working emphasis and prospects of PLLA in packaging field were put forward. |
