The adaptation of biopolymers into flexible packaging offers sustainable alternatives to polyolefins but presents challenges in processing and performance.
Brittleness, sensitivity to shear, temperature, and hydrolysis complicate transitions from polyolefins. Strategies such as blending or incorporating masterbatches enhance processability and mechanical properties, broadening application potential.
Six‑month studies of monolayer films provide critical insight into shelf life and structural stability compared to petroleum-based packaging.
