Among various biorenewable polymers, poly(2,5-ethylene furandicarboxylate) (PEF) has a large potential to replace fossil-based poly(ethylene terephthalate) (PET) for different applications. However, despite showing better gas barrier properties compared to PET, the inferior mechanical properties of PEF hinder its potential applications. This study reports the toughening of PEF with linear low-density polyethylene (PE) via melt blending by reactive compatibilization at the polymer-polymer interface and benchmarking against similar PET/PE blends. The wettability and spreading coefficient predictions indicate a preferable location of the ternary component (styrene-ethylene/butylene-styrene-graft-maleic anhydride (SEBS-
