The types of edge banding common in the prior art include by material: PVC edge banding, ABS edge banding, melamine edge banding, etc. The ABS resin is one of the most advanced international materials at present, the ABS edge banding made of the ABS resin is not doped with calcium carbonate, the edge banding looks bright and smooth after trimming, and the phenomenon of whitening can never occur, however, the market price of the ABS resin is about 12800 yuan/ton, the manufacturing cost is higher, and the price is about 1 time higher than that of a PVC edge banding with the same specification in market popularization. The melamine edge banding is commonly called paper edge banding, and has the advantages of easy adhesion, difficult expansion and difficult deformation when meeting cold and heat, but easy breaking due to the characteristics of the melamine edge banding during the production and the transportation of furniture. The PVC edge banding has the advantages of being light, made of plastics, easy to process, high in quality and low in price, and the like, so that the PVC plastic edge banding is the most common edge banding on the market at present. When the PVC edge sealing strip is processed, a PVC base material consisting of PVC resin, calcium carbonate powder and various auxiliary materials (a stabilizer, DOP oil, ACR, stearic acid, carbon white powder, toner, an anti-aging agent and the like) needs to be prepared, then the PVC base material is printed by ink, and then UV paint is coated on the PVC base material in a rolling way and then the PVC base material is cured.
