The present invention relates to a double sided black light shielding tape, and to a manufacturing method thereof. More particularly, the double sided black light shielding tape comprises: a light detaching sheet layer; a heavy detaching sheet layer; and a black pigment-containing adhesive layer arranged between the light detaching sheet layer and the heavy detaching sheet layer. The light detaching sheet layer has detaching strength within a range of 3-20 gf/25 mm, and the heavy detaching sheet layer has detaching strength within a range of 30-70 gf/25 mm. The difference in the detaching strength of the light detaching sheet layer and the heavy detaching sheet layer is 27-50 gf/25 mm. The double sided black light shielding tape can be made thin in comparison to a conventional product. |
