Luminescent biodegradable films have recently emerged as a promising class of smart packaging materials that combine sustainability with optical sensing functionality. These films are not only compostable but also capable of detecting spoilage markers, including pH changes, gas emissions, and moisture levels. Therefore, this review critically examines recent advancements in biodegradable film materials, luminescent sensing technologies, and fabrication strategies, with a focus on developments reported primarily after 2015. In addition to summarizing progress, key challenges related to luminescence stability, safety and migration concerns, production cost, scalability, and regulatory compliance are highlighted. The dual functionality of compostability and responsiveness to spoilage indicators position luminescent biodegradable films as transformative innovations with the potential to extend shelf-life, increase consumer confidence, and reduce food waste. However, their widespread commercialization remains constrained by technical and regulatory barriers. This review further identifies research gaps and future directions necessary for translating luminescent biodegradable films from laboratory-scale demonstrations to commercially viable, safe, and sustainable intelligent food packaging systems.</div></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":"55 ","pages":"Article 101778"},"PeriodicalIF":10.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148184878","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a nanoparticle-free and fluorine-free strategy for fabricating superhydrophobic paper utilizing exclusively Generally Recognized as Safe (GRAS) additives—shellac and alkyl-ketene dimer (AKD)—in conjunction with the intrinsic micrometer-scale roughness of commercial kraft paper. By optimizing a 25 vol% shellac loading relative to the AKD emulsion, a hierarchical micro/nano-textured film was formed via spontaneous phase separation and covalently grafted to cellulose through β-ketoester linkages using a single wire-rod pass. The resulting paper attained a static water contact angle of 155.3°, a sliding angle of 4.74°, and a surface free energy of 2.50 mJ/m², comfortably exceeding the superhydrophobic threshold. Water absorption was reduced by 87.8% (to 3.2 g/m²), while the mechanical integrity remained largely on par with the base paper. The surface demonstrated exceptional self-cleaning performance, resistance to staining from diverse aqueous media, and robust durability against thermal stress (up to 120 ℃), mechanical abrasion, and 12-month environmental aging. Free from fluorinated moieties and inorganic nanofillers, this material is fully recyclable and compliant with food-contact regulations. The integration of green chemistry with high-throughput manufacturability offers a practicable platform for scalable, plastic-free food packaging within a circular economy framework.</div></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":"55 ","pages":"Article 101781"},"PeriodicalIF":10.6,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148184879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
