It is recognised that several factors contribute to the behaviour of the paperboard, including the fibre origin, physic-mechanical treatments, bulk composition and material surface treatments. This work aimed at addressing the relationship between these factors, by conducting a deep physic-chemical characterisation of packages of cherry tomato collected in 4 European countries, in both high and low-cost supermarkets. Samples varied in terms of fibre origin, treatments (bleaching, printing), functional additives (surface or bulk agents). Statistical analysis demonstrated that it is possible to group samples according to different properties that are inter-related, such as the type of fibre and typical formulations (i.e. plasticizers and functional additives used). Materials varied significantly in their performance regarding the hydrophobicity character. Repulpability was also tested as step needed for recyclability.

PNIPAAm/LEO/PLA film controlled-release LEO with cumulative oil release rates of 24.41 % and 66.82 % at 20 °C and 40 °C after 24 h incubation, showing 39.50 % and 9.91 % elevation in comparison with LEO/PLA film. During the strawberry storage period, the PNIPAAm/LEO/PLA treatment resulted in a significantly reduced decay rate and weight loss, delayed firmness, and total soluble solid deterioration. In conclusion, the PNIPAAm/LEO/PLA film effectively controlled the release of LEO and delayed strawberry quality deterioration at various storage temperatures, thereby extending its shelf life.</div></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":"50 ","pages":"Article 101561"},"PeriodicalIF":8.5,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144571586","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}
