An interlayer comprising a thermoplastic resin, various amounts of epoxidized vegetable oil, and optionally a conventional plasticizer. The use of thermoplastics, epoxidized vegetable (plant) oils, and, in some cases, conventional plasticizers, may be associated with other properties typically associated with increased fluidity (eg, increased blocking and creep, leaching, surface It creates a synergistic effect that can increase the fluidity of the interlayer without sacrificing roughness formation, reduced mechanical strength, reduced production capacity. In this regard, the epoxidized vegetable oil acts as a fluidity improver, resulting in a high fluidity interlayer. As a result, the resulting thin interlayer has improved flow characteristics, so a thinner interlayer can be utilized when forming a multilayer panel.
