Plastic (especially polyethylene), per- and polyfluoroalkyl substances (PFAS), modified plant oils, such as acrylated epoxidized soybean oil (AESO), are commonly used for paper coatings due to their excellent packaging performance. However, plastic- plant-oil-coated is not recyclable PFAS toxic. To address these issues, a photocurable AESO emulsion was blended with degradable cross-linker, oligoacrylate lactide/glycolide, enhance the recyclability of coated paper. In parallel approach, (ESO) glycolic methacrylic groups further promote both cases, emulsions were prepared, cast onto paper, UV-cured prior testing water resistance using Cobb-1800 kit rating tests, respectively. The repulpable recyclable, validated through standard recycling methods. Furthermore, vermicomposting tests confirmed compostability This work demonstrates unique, naturally derived alternative plastics in applications.

Conventional nonfunctional polyester-coated paper is suitable for packaging, but this coated nonrecyclable. Herein, we report coating materials recyclable and industrially compostable using functionalized polyester blends. First, carboxylic acid-functionalized polylactic acid (CPLA) poly(butylene adipate-co-terephthalate) (CPBAT) were synthesized. CPLA, either alone or as a blend of CPLA CPBAT, was emulsified then applied coating. The tested to evaluate its water oil repellency, gas moisture barrier, sealing, mechanical properties index. paper's repulpability recyclability fully validated by certified methods. compostability the CPBAT- CPLA-coated papers also confirmed. This newly PFAS- persistent microplastics-free, nature fits into circular economy approach.
