Poly(ethylene furanoate) (PEF) films, recognized for their promising barrier and mechanical properties, offer a sustainable alternative to conventional petrochemical-based poly(ethylene terephthalate) (PET). In this study, the effects of biaxial orientation parameters on properties biaxially oriented PEF (BOPEF) PET/PEF/PET multilayer coextrusion films were comprehensively investigated explore potential high-barrier packaging materials. Optimized conditions BOPEF achieved at stretch ratio 3.5, temperature 105 °C, rate 100%/s, which enhanced tensile strength 145 MPa, modulus elasticity 4.1 GPa, elongation break 88%. Moreover, these exhibited superior with an oxygen permeability 0.0083 barrer, carbon dioxide 0.0031 water vapor 5.54 × 10–15 g·cm/(cm2·s·Pa). Under same conditions, further improved by adding 20% films. The oxygen, dioxide, 32%, 50%, 74%, respectively. pilot-scale production validated laboratory findings, demonstrating stability in film performance consistent thus confirming feasibility industrial-scale applications packaging. findings from study not only underscore as high-performance material but also illustrate critical importance process optimization achieving desired properties. These results build solid foundation broader industrial application PEF, enhancing its viability scalable environmentally friendly industry.

The production of plastic materials consumes a large amount petroleum resources, leading to the depletion these resources and environmental problems associated with disposal. Recently, demand for sustainable bioplastics has increased, necessitating an appealing strategy development using raw materials, including inedible that degrade rapidly under mild conditions. In this study, poly(alkylene xylosediglyoxylates)-co-poly(lactic acid) (PAX-co-PLA) is synthesized from xylose lactic acid, which can be conditioned through two-step condensation process. thermal stability mechanical properties tuned by changing compositions copolymers. Among PAX-co-PLA, PEX-co-PLA exhibits high Tg (glass transition temperature) 106 °C PHX-co-PLA elongation at break ± 4%. biodegradability evaluated, focusing on neat PHX PHX-co-PLA, exhibit toughness. Both significant disintegration in compost. Neat BOD (biological oxygen demand) 14% 13% seawater, respectively. Furthermore, contact angle (76.2 1.7°) comparable PLA, retains its shape 2 weeks water 20 °C, shows improved resistance compared PHX. With thermoformability, resistance, partial biodegradability, PAX-co-PLA expected have wide applications address issues, reduction microplastic pollution.
