To overcome these constraints, this study introduces an innovative coating strategy that functionalizes PE films with a composite layer of polyvinyl alcohol (PVA), silane‐modified layered double hydroxide (ALDH) and tannic acid (TA). The optimized film (PE‐PVA/ALDH/TA 10 ) demonstrates exceptional properties, achieving an ultra‐low oxygen transmission rate of 0.033 cm 3 m −2 day −1 atm −1 and a high 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radicals with a scavenging rate of 79.2%. Structural analysis confirms that ALDH and TA promote the formation of a dense hydrogen‐bonded network within the PVA matrix, which significantly reduces oxygen permeability while imparting strong antioxidant activity. Furthermore, the coated film retains high visible‐light transparency and exhibits exceptional UV‐blocking efficiency, reaching 97.3% in the UVC–UVB range. Preservation tests using bananas validate the material's effectiveness in delaying ripening, minimizing weight loss and maintaining fruit quality. This work presents a scalable, multifunctional packaging solution that combines ultra‐high barrier performance with antioxidant functionality for extended food preservation.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to explore the effect of incorporation of carbon quantum dots (CDs) into a corn starch/polyvinyl alcohol matrix to develop pH‐mediated fluorescent sensing smart films. CDs with an average particle size of 5.496 nm were successfully prepared using a hydrothermal method incorporating citric acid and urea as raw materials, which are rich in hydrophilic groups, especially nitrogen‐containing groups, and exhibit pH fluorescence response characteristics. The CDs presented hydrogen bonding–dominated interactions with the film while having no significant effect on the microstructure and crystal structure. They were uniformly dispersed in the films, and the loading of CDs endowed the films with UV‐shielding ability, excellent mechanical properties and thermal stability. The pH‐mediated fluorescence sensing function of the film was verified by simulating pH changes in a high‐protein food storage environment using acetic acid and ammonia, showing a 62.91% increase in fluorescence intensity from pH 3.5 to 8.5. This work provided an idea for developing a new smart packaging system.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pts.70038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on the safety of the prepared dishes packaging. First, migration tests were designed to fully simulate the entire contact process between polyethylene terephthalate/aluminium foil/polyamide/retort cast polypropylene (PET/Al/PA/RCPP) composite films packaging pouches and prepared dishes throughout the full chain, based on GB 31604.1‐2023. A comparison was made with room temperature simulation tests to investigate the effects of high temperature on migrants. Gas chromatography‐mass spectrometry (GC‐MS) and ultra‐high‐performance liquid chromatography quadrupole time‐of‐flight mass spectrometry (UPLC‐QTOF‐MS) were used for the non‐target screening of the migrants. A total of 17 non‐volatile compounds were identified in the full‐chain simulation, while only seven were detected in the room temperature simulation. Especially, the oligomers of inner polyamide 6 (PA 6) migrated through the RCPP layer into the simulants. Principal component analysis (PCA) and orthogonal partial least squares‐discriminant analysis (OPLS‐DA) were employed to visualize differences in migrants between the full‐chain and room temperature simulation. Based on the quantitative analysis, risk assessment was conducted. Ethylene glycol adipate cyclic oligomers exceeded the toxicological concern threshold under full‐chain simulation, necessitating more refined risk assessment approaches. These results confirm that high temperature promotes the migration of substances from the packaging, suggesting that prepared dishes should avoid hot filling in the future. If conditions allow, consumers had better not heat them in their packaging to minimize exposure to migrants.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"39 4","pages":"471-484"},"PeriodicalIF":0.0,"publicationDate":"2025-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pts.70046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147881857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a ratiometric fluorescent nanofibre film was successfully developed for real‐time visual monitoring of shrimp freshness. The film was constructed by embedding an amine‐responsive fluorophore, fluorescein isothiocyanate (FITC) and a stable reference fluorophore, Eu (DBM) 3 Bpy, into an electrospun polyvinyl alcohol (PVA) matrix. The sensing principle relies on the pH‐driven enhancement of FITC's green emission (530 nm) in the presence of biogenic amines, whereas the Eu‐complex provides a constant red reference signal (610 nm). This dual‐emission system creates a clear fluorescence colour change from orange to yellow‐green as shrimp spoils. The sensor exhibited high selectivity and a rapid response, detecting spoilage within 6 h at 25°C. The maximum colour difference (ΔE) reached 64.78, allowing for unambiguous visual detection. This robust and easy‐to‐fabricate nanofibre film holds great promise for practical applications in food safety and intelligent packaging technology.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"39 3","pages":"299-313"},"PeriodicalIF":0.0,"publicationDate":"2025-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pts.70035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147908929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impacts of CS‐TP nanoparticles on the physicochemical, antioxidant and antimicrobial properties of CMC/S film were evaluated, along with the effects of composite films on pork preservation. The introduction of CS‐TP nanoparticles strengthened the mechanical strength and water vapour barrier performance of the CMC/S film while reducing its hydrophilicity. The CMC/S films containing CS‐TP nanoparticles exhibited excellent UV‐blocking and antioxidant properties, as well as strong antibacterial effects against Staphylococcus aureus and Pseudomonas aeruginosa . The in vitro release results demonstrated a sustained release of TP from the composite films, with the release kinetics fitting the Weibull model ( R 2 = 0.9742–0.9867). The release of nano‐encapsulated TP is collectively governed by surface erosion, nanostructural degradation, molecular diffusion and polymer chain relaxation. Furthermore, preservation experiments demonstrated that CMC/S films containing CS‐TP nanoparticles effectively inhibited microbial growth and oxidative deterioration in refrigerated (4°C) pork loin while preserving colour and texture properties. This eco‐friendly, sustained‐release, multifunctional material shows considerable promise for food packaging applications and provides valuable insights for designing other food preservation materials.","PeriodicalId":19626,"journal":{"name":"Packaging Technology and Science","volume":"39 2","pages":"161-180"},"PeriodicalIF":0.0,"publicationDate":"2025-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/pdfdirect/10.1002/pts.70027","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147330391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three treatment systems were evaluated: laccase (L) alone, an L/lauryl gallate (LG) binary system, and a L/LG/chitosan (CTS) ternary system. The optimal conditions for the L/LG/CTS system were determined as 40.0 U·g −1 L, 1.0 wt.% LG, 1.0 wt.% CTS, 3.0 wt.% pulp consistency, a reaction temperature of 50°C, and a reaction time of 4 h. Compared with untreated moulded pulp products, which exhibited poor barrier properties (static water contact angle: 0°, Cobb 60 : 141.21 ± 5.24 g·m −2 , Kit test: 0/12) and limited mechanical performance (tightness: 1.04 ± 0.03 g·cm −3 , tensile index: 29.86 ± 1.32 N·m·g −1 , bursting index: 0.85 ± 0.07 kPa·m 2 ·g −1 , tear index: 5.72 ± 0.28 mN·m 2 ·g −1 , folding resistance: 82 ± 2), the L/LG/CTS‐treated products demonstrated notable improvements. Specifically, hydrophobic/oleophobic properties improved markedly (static water contact angle: 104.5° ± 2.9°, Cobb 60 : 14.83 ± 0.71 g·m −2 , Kit test: 8/12) and mechanical strength increased substantially (tightness: 1.18 ± 0.03 g·cm −3 , tensile index: 34.78 ± 0.96 N·m·g −1 , bursting index: 1.88 ± 0.09 kPa·m 2 ·g −1 , tear index: 6.23 ± 0.30 mN·m 2 ·g −1 , folding resistance: 93 ± 5).

These findings indicate that the L/LG/CTS ternary system is a highly effective and sustainable strategy for enhancing both barrier and mechanical properties of moulded pulp products, positioning them as a promising alternative to petroleum‐based plastics for food packaging applications.

The film exhibited good mechanical properties as well as excellent water resistance and antioxidant properties.
