Because this trend looks set to continue, various start-ups have developed concepts for to-go items, where customers are charged on a pay-per-fill basis, while the company takes care of cleaning and replacing the packaging. And by using smart labels – microchips that can store much more data than a conventional barcode – reuse concepts can be integrated into logistics processes with optimum results. At Greiner Packaging, we too are working on a wide variety of reuse concepts for sectors such as food service.
