At the top, a box labeled “Search string (generic)” presents the search strategy. The search string reads: TITLE-A B S-KEY (“smart packag asterisk” OR “intelligent packag asterisk” OR “interactive packag asterisk” OR “active packag asterisk” OR “connected packag asterisk” OR “smart label asterisk” OR “creative packag asterisk” OR “enhanced packag asterisk”) AND TITLE-A B S-KEY (“logis asterisk” OR “supply chain asterisk” OR “operation asterisk” OR “handling asterisk” OR “transport asterisk” OR “inventory asterisk” OR “warehous asterisk” OR “distribu asterisk” OR “storag asterisk” OR “procur asterisk” OR “purchas asterisk” OR “freight asterisk” OR “rout asterisk” OR “schedul asterisk”) AND TITLE-A B S-KEY (“circular asterisk” OR “closed loop asterisk” OR “recyc asterisk” OR “reus asterisk” OR “revers asterisk” OR “re-manu asterisk” OR “remanu asterisk” OR “reduc asterisk” OR “redesign asterisk” OR “rethink asterisk” OR “refuse asterisk” OR “resell asterisk” OR “upcyc asterisk” OR “downcyc asterisk” OR “extended producer responsibilit asterisk” OR “E P R asterisk” OR “repurpos asterisk” OR “recover asterisk” OR “sharing econom asterisk” OR “obsolenc asterisk”). The search engines are “Scopus” and “Web of Science”. An arrow leads downward to a box labeled “Scopus: 1193” and “Web of Science: 1101”. To the right, a dashed box lists the inclusion criteria: “a. infinity to 31.12.2025”, “b. Articles, book chapters, and reviews”, and “c. English language”. A dased arrow from this dashed box leads to box labeled box labeled “Scopus: 1193” and “Web of Science: 1101”. A downward arrow leads to a box labeled “Records identified for title and abstract review, n equals 1762”. A dashed rightward arrow from this downward arrow leads to a dashed box labeled “Duplicates excluded, n equals 532”. Another downward arrow leads to a box labeled “Reports intended for full text review, n equals 133”. A dashed rightward arrow from this downward arrow leads to a dashed box labeled “Records excluded, n equals 1629”. Below, the exclusion criteria box reads “Exclusion criteria (E dimension, P E O): a. Not addressing smart packaging. b. Focused only on material development or packaging description without logistic relevance”. A further downward arrow leads to the final box labeled “Studies included in the review, n equals 59”. A dashed rightward arrow from this downward arrow leads to a dashed box labeled “Reports excluded, n equals 74”. Below, the exclusion criteria box reads “Exclusion criteria (O dimension, P E O): a. No clear influence of smart packaging on logistics practices. b. No identifiable implication for C E strategies”.SLR search and selection process
