Biodegradable Polyester-Starch Composite Films Functionalized with Phenolic Compounds: Advances, Challenges, and Prospects for Sustainable Active Packaging.
Review in Polymers, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The growing demand for sustainable food packaging has intensified interest in biodegradable materials that can reduce environmental impact while preserving food quality. Among these materials, biodegradable polyester-starch composite films functionalized with phenolic compounds have gained attention as promising active packaging systems. They combine the melt processability and structural stability of polyesters, such as poly(lactic acid) (PLA), poly(butylene adipate-co-terephthalate) (PBAT), poly(butylene succinate) (PBS), and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) with the renewability and biodegradability of starch and the antioxidant, antimicrobial, and UV-protective functions of phenolics, such as ferulic acid, quercetin, tea polyphenols, and anthocyanins. This review discusses recent advances in the selection of biodegradable polyesters, starch and thermoplastic starch blending, phenolic incorporation strategies, and their effects on compatibility, morphology, mechanical strength, barrier properties, optical behavior, release, and active packaging functionality. The characteristics and functionality of these films are governed not only by the individual components but also by phase morphology, interfacial interactions, phenolic location, processing conditions, and release control. Key challenges include polyester-starch incompatibility, TPS moisture sensitivity, phenolic stability during melt processing, migration safety, controlled release, and industrial scale-up. Collectively, biodegradable polyester-starch films functionalized with phenolic compounds represent a promising route for developing next-generation sustainable active packaging and may contribute to circular economy approaches.
