Detergent capsules are a laundry innovation based on water-soluble polymer films that ensure ease of use and accurate dosing. Polyvinyl alcohol (PVA) is widely used due to its water solubility and environmental friendliness; however, it is sensitive to moisture, which may reduce film strength. The addition of microfibrillated cellulose derived from oil palm empty fruit bunch (OPEFB) waste has the potential to reinforce PVA films and support the development of more sustainable detergent capsules. This study aims to produce microfibrillated cellulose as a reinforcing material, fabricate MFC-based composite films for detergent capsule applications, and determine the appropriate MFC concentration based on water absorption, tensile strength, elongation at break, and water vapor transmission rate (WVTR). MFC was obtained through delignification, bleaching, and acid hydrolysis. PVA films were prepared with MFC variations of 0–12.5% (w/w). The addition of 2.5% MFC showed the best performance, with a tensile strength of 63.33 MPa, elongation at break of 110.64%, WVTR of 4.09 g/h·m², water absorption of 139.74%, capsule dissolution time of 49 seconds, and elongated fibril morphology observed by SEM.
