Carbon black (CB) has the ability to be used as a filler to inrprove the thennal and mechanical properties of the packaging material. This study aimed to determine the effect of CB composition variations as a filler on low-density polyethylene (LDPE) nanoconrpositet o physical properties, rnechanical propertias, and thermal properties. The fabrication of LDPE/CB nanocomposite-basepda ckaging material was performed by hot press and cold press method with LDPUCB composition variations of 95: 5, 90:10" 85:15 and 80:20 7ofi. The effects of CB as filler on LDPE thermoplastic were characterized using FTIR, XRD, SEM, UTM, and TGA. The result of IR spectra analysis showed that the interaction between LDPE and CB in ttre solution was limited to physical bonds, the analysis using XRD generally follows the LDPE diffraction pauern. The most optimum composition result obtained from the variation of 5Vowt CB, where the surface morphology using SEM of it tends to agglomerate" the mechanical analysis using UTM showed a tensile strength of 21.45 MPa elongation at 436.21 mrn, and rnodulus yotang?y';6.22M P4 and thermal analysis using TGA showed chmges mass at a decomposition temperature of 488.70 "C.
