Demonstrates improved performance of alginate-PBAT blend films for sustainable packaging, suggesting a viable alternative to traditional plastics.

Explore methods to enhance the performance of sodium alginate films for sustainable packaging applications.
Compared ionic crosslinking with polymer blending methods.
Formulated and tested films using sodium alginate and PBAT.
Measured tensile strength, water vapor transmission, and thermal stability.
Ionic crosslinking improved tensile strength to 41 MPa but increased brittleness.
Polymer blending with 30 wt% PBAT yielded films with 47 MPa tensile strength.
Blended films exhibited better moisture barrier properties and thermal stability.
