The invention relates to a synthesis back glue paper and a production method. The synthesis back glue paper comprises a middle basic layer, wherein silicone oil layers, bonding layers, side basic layers and ink coating layers are sequentially arranged from the middle basic layer to both sides respectively, and the middle basic layer and the side basic layers respectively adopt plastic materials. The synthesis back glue paper has an integrated structure. By utilizing the synthesis back glue paper, double face airbrushing is realized, and the utilization and use convenience are high. The production method comprises the following steps: firstly combining the ink coating layers and the side basic layers, then treating the middle basic layer to form the silicone oil layers, and then bonding the other side after firstly bonding one side. The synthesis back glue paper has high production efficiency, and demand of efficient production is met.
