Cellulosic microfibrils (SMF) and microparticles (SMP) extracted from soybean hulls were used in films and also combined with wood-based micro and nanofibrillar cellulose (MNFC) in hybrid systems. During film consolidation a remarkable reduction in water drainage was observed in the presence of SMF and SMP. The hybrid films displayed strength (elastic modulus and strength at rupture) and barrier performance similar to those of neat MNFC films, thus offering an option for reduced cost while keeping a performance from synergistic contributions of the components. Furthermore, dense films with low-porosity, a characteristics essential for barrier properties, can be easily produced by replacing up to 75 % of MNFC with SMF or SMP.
