Tape core of ultrathin anti-floating-word secrecy correction tape and production technology thereof

The invention discloses a tape core of ultrathin anti-floating-word secrecy correction tape and a production technology thereof. The tape core comprises a stripping layer, a writing covering coating and a pressure-sensitive adhesive layer, wherein the stripping layer, the writing covering coating and the pressure-sensitive adhesive layer are sequentially arranged on an anti-sticking base material in a coating mode, a leakproof auxiliary combining layer and an aluminum covering layer are further sequentially arranged between the writing covering coating and the pressure-sensitive adhesive layer, and a high-covering anti-floating-word structure is formed. During production, all the layers are sequentially arranged on the anti-sticking base material in a coating and connected mode. According to the tape core, the writing covering coating can not be subjected to color changing and hardening, the combining strength of the aluminum covering layer can be obviously improved through the leakproof auxiliary combining l
