[0006] A novel PET refraction embossed card structure comprises an upper PET film layer, a silver card paper layer, a single copper paper layer and a lower PET film layer arranged in sequence from top to bottom, wherein the upper PET film layer and the silver card paper layer are hot-pressed and laminated to form an upper layer combination, the single copper paper layer and the lower PET film layer are hot-pressed and laminated to form a lower layer combination, and the upper layer combination and the lower layer combination are laminated.
[0007] It should be noted that the silver card paper layer can be replaced by a photoetching paper layer, wherein the silver card paper layer or the photoetching paper layer is printed with images and embossed with a relief pattern before being hot-pressed and laminated with the upper PET film layer, and the image printing is at room temperature and the pressure is 20 Pa.
[0008] It should be noted that the silver card paper layer or the photoetching paper layer is hot-pressed and laminated with the upper PET film layer, and the bottom of the upper PET film layer is coated with hot melt adhesive before the hot-pressing and lamination.
[0009] It should be noted that the single copper paper layer can be replaced by a double copper paper layer, wherein the single copper paper layer or the double copper paper layer is printed with images before being hot-pressed and laminated with the lower PET film layer.
[0010] It should be noted that before the single copper paper layer or the double copper paper layer is connected by hot pressing and pasting with the lower PET film layer, the bottom of the lower PET film layer is coated with hot melt adhesive.
[0011] It should be noted that the image is a pattern or text, or a combination of patterns and text.
[0012] It should be noted that during the process of hot pressing and pasting of the silver card paper layer or the photoetching paper layer and the upper PET film layer, the hot pressing temperature is 155 DEG C, and the pressure is 10 Pa.
[0013] It should be noted that during the process of hot pressing and pasting of the single copper paper layer or the double copper paper layer and the lower PET film layer, the hot pressing temperature is 155 DEG C, and the pressure is 10 Pa.
[0014] It should be noted that during the process of pasting and connecting of the upper layer combination and the lower layer combination, glue is used for pasting and connecting.
[0015] The beneficial effect of the utility model lies in that the PET refraction embossed card combined with the structure can greatly reduce the requirements for workshop and equipment, is easier to produce, is easier to control quality, and thus increases benefits. BRIEF DESCRIPTION OF DRAWINGS
