Abstract. Rising carbon dioxide (CO₂) emissions creates a dual challenge: environmental impact and material performance limitations in packaging systems. Polyethylene terephthalate (PET), extensively applied in beverage bottles and pharmaceutical packages, has poor gas barrier performance that causes leaking of CO₂ and reduced stability of the product. PET membranes and molybdenum disulfide (MoS₂) nanosheets were engineered in this study to improve gas barrier property. The addition of two-dimensional nanofillers facilitated efficient interfacial interaction in the polymer matrix, thus suppressed the free volume channels and limit the diffusion of CO₂. Structural characterization i.e. SEM (scanning electron microscopy) confirmed uniform nanosheet dispersion, while gas permeability studies revealed a marked 86% reduction in CO₂ permeability relative to pristine PET. These developments reveal the potential of PET/MoS₂ nanocomposites as scalable, cost-effective materials for enhancement of product shelf life and reduction of carbon dioxide losses through leakage in packaging applications. This work aligns with climate action goals by advancing sustainable materials that contribute to CO₂ management through improved containment and utilization.
