文摘
- •
Multi-layer film based on poly(lactic acid) (PLA) and fish gelatin was prepared.
- •
Oxygen permeability of PLA decreased more than 8-fold due to multi-layer structure.
- •
A reduction of 91% in WVP was obtained for multi-layer film compared with gelatin.
- •
The designed multi-layer film maintains high level of optical clarity.
- •
This barrier film is a promising candidate to polymeric food packaging materials.
