Red ginger is an herbal plant that contains active components and can be used to control microorganisms. In this study, active packaging in the form of an antimicrobial sachet was developed. The red ginger essential oil was incorporated into silica-cellulose nanocomposite in powder form in a closed sachet. The silica-nanocellulose composite was fabricated through a sol-gel permeation process in nanocellulose hydrogel. Nanocellulose was isolated from oil palm empty fruit bunches by mechanical treatment, a combination of ultrafine grinding and ultrasonication. Nanocellulose hydrogel was immersed in a sodium silicate solution at three different times. The obtained gel was soaked in 2 M sulfuric acid for 4 hours to produce a silica-nanocellulose composite. Release property of red ginger essential oil from the closed sachet was observed. The effectiveness of the produced antimicrobial sachets depends on the release of the antimicrobial agent from the sachets. © Published under licence by IOP Publishing Ltd.
