This study aimed to produce bilayer films spiked with white round grapefruit essential oil and apply them to preserve <i>Lycium barbarum</i>. A chitosan/polyvinyl alcohol film doped with white round grapefruit essential oil was prepared as an inner film, and a polyethylene terephthalate film was prepared as an outer film through a solution casting method. The volatile compounds of white round grapefruit essential oil (87.5573%), mainly d-limonene (34.389%), <i>cis-p</i>-mentha-2,8-dien-1-ol (5.1
