Further, the thickness of described black ink layer is 1 ~ 12 μm.
Further, the thickness of described first pressure-sensitive adhesive layer, the second pressure-sensitive adhesive layer is independently 2 ~ 10 μm.
Further, the thickness of described first release film, the second release film is independently 12 ~ 125 μm.
Further, described black ink layer is black polyester ink layer or black polyurethane ink layer or black rubber ink layer.
Further, described first pressure-sensitive adhesive layer, the second pressure-sensitive adhesive layer are independently acrylic pressure sensitive glue-line or rubber pressure-sensitive adhesive layer or polyurethane pressure sensitive glue-line.
Further, described first release film, the second release film are PET release film.
The beneficial effects of the utility model are:
The innovation of the utility model scheme is using black ink layer as laminboard layer, on the one hand, can provide support for pressure-sensitive adhesive layer, facilitate the needs of later process cross cutting, ensures that pressure sensitive adhesive is at the excessive glue of storage and use procedure, cross cutting dimensional stabilizing simultaneously; On the other hand, owing to adopting black ink layer as laminboard layer, avoid and add black pigment in pressure-sensitive adhesive layer, so there is not the risk reducing pressure-sensitive adhesive layer force of cohesion and peeling force, simultaneously the opacity of black ink layer and degree of screening enough, the total thickness of double sticky tape can be reduced further, can reach 8 μm thick (not comprising release film thickness), meet the trend that current phone field is thin.
