The existing grain lettering film is mostly made by adopting a PET film, a PVC film, a PC film and the like as release films and forming a resin molding layer, a grain layer and a hot melt adhesive layer through coating by a coating process. Due to the performance limitation of the colloid of the resin molding layer, the lettering film has the defects of poor molding, scratch resistance and the like, and can not meet the requirements of zipper films and some shoe and clothes products which need scratch resistance.
Patent document CN 102936476B discloses a method for manufacturing a thermal transfer adhesive film, which is equivalent to the method for manufacturing a lettering film in practical application, and improves a hot melt adhesive layer without improving a resin molding layer, so that the overall quality of the lettering film is not improved.

4) printing a line layer on the resin molding layer;
5) coating hot melt adhesive on the grain layer to form a hot melt adhesive layer, and manufacturing a scratch-resistant grain lettering film; the hot melt adhesive layer has higher adhesive force with the surface of the printing stock, so that the grain layer is firmly combined with the surface of the printing stock, and the hot melt adhesive layer must be matched with a printing material and selected according to different printing stocks.
The further improvement is that; the thickness of the release film is 5c-10 c.
The further improvement is that: the resin molding layer adopts an extrusion coating process, a double screw is used in an extrusion stage, the temperature of each section of an extruder is 180-240 ℃, and the rotating speed of the screw is 200-400 r/min; coating the wet film with the thickness of 20c-30c, drying in a 12-section oven at 60-115 ℃ at the speed of 75-100 m/min.
