000147119 5203_ $$aPhosphate derivatives contain a high number of reactive groups that interact functionally with various polymers. Tetrasodium pyrophosphate (Na₄P₂O₇), sodium tripolyphosphate (Na₅P₃O₁₀), and sodium hexametaphosphate (Na₆(PO₃)₆) were incorporated into bioplastic polybutylene-adipate-terephthalate (PBAT) blended with thermoplastic cassava starch (TPS) in blown films. Their physicochemical, morphological, thermal, and antimicrobial properties were investigated. PBAT/TPS blended films were compounded via blown film extrusion to produce functional packaging. Infrared spectra indicated starch modification through the disruption of anhydroglucose monomer units, analyzed by ATR-FTIR, providing a more amorphous fraction and altering the properties of the films. PBAT/TPS films containing phosphate compounds exhibited non-homogeneous structures, with dispersed clumps within the film matrices that decreased tensile strength. The incorporation of phosphate compounds modified the storage modulus and relaxation temperature of PBAT/TPS films, influencing molecular mobility, decreasing heat transfer efficiency in seal strength, and enhancing stiffness due to starch disruption and interaction between the phosphate compound and the PBAT/TPS matrix. Wettability and permeability of PBAT/TPS films were modified by changes in polymer structure.
