<p>The present invention relates to a triple composite film tape for preventing discoloration. The triple composite film tape according to the present invention is manufactured by forming a first adhesive layer (4) by coating an adhesive on a printed layer (3) of the internal layer of a PET- or PC-based first film (2) which has the external surface having a primer or a corona layer (1) and the internal surface having a printed layer (3); combining white base paper (5) on the first adhesive layer (4); forming a second adhesive layer (6) by coating an adhesive on the internal surface of the white base paper (5); combining a PET- or PC-based second film (8) which has the external surface having a printed layer (7) and the internal surface having a primer or corona layer (9), on the second adhesive layer (6); forming a third adhesive layer (10) by coating an adhesive on the inner primer or corona layer (9) of the PET- or PC-based second film (8); and attaching release paper (11) to the third adhesive layer (10). The present invention has a remarkable effect of preventing discoloration by blocking foaming gas, which is a main cause of discoloration of a refrigerator door or a front cover of an air-conditioner, so that gas generated in foaming is not able to reach an ink layer, by forming an impermeable thin film with a film tape, in which films are laminated; reducing the manufacturing costs by reducing the background printing to one time printing; and preventing the foaming solution or the color on the back side from affecting the design layer of glass by printing on one side of the film.</p> |
