From orchard waste to packaging innovation: Nanofiber reinforced biopolymer laminations for paper packaging, TAPPICon26

In this study, lignocellulose nanofibers (LCNF) with two different lignin concentrations (5% and 7%) were successfully extracted from peach pits through a sequential and controlled process. This process involved bleaching ground peach pits, alkali treatment, and mechanical fibrillation using a planetary ball mill to yield nanoscale fibers with diameters of 3-5 nm. Further, pearl millet starch was isolated by wet milling and reinforced with LCNFs (5% and 7% lignin) to develop nanocomposite films. The films were printed with the Clemson Tigers logo. Considering the exceptional properties of films, it was further laminated on the paper using Laminator Model 7000.
