In the present invention, the coating paste has the following two advantages.
First, the present invention uses a relatively smaller amount of coating than the amount of coating of the prior art coated brand tapes, where the ink penetrates relatively more easily to the back, so the applicant has creatively added a masking filler to the coating glue for ink adhesion, achieving the dual advantage of being thin and impermeable, where there is a slight loss of hand feel, after all the masking filler is in the form of a solid powder.
Secondly, according to the problems, the applicant introduces the softening agent creatively again, so that the problem of hand feeling reduction caused by the shielding filler is perfectly solved, and finally the label tape is thin, good in hand feeling and impermeable in ink, and is far superior to the common label tape on the market.
The coating adhesive is lower than the coating amount of the existing coating label tape, so that the thickness is further reduced, the hand feeling is improved, and the problem that the printing ink is easy to penetrate to the back side due to the relatively small coating amount is solved by adding the shielding filler, so that the label tape disclosed by the invention has the double advantages of being thin, good in hand feeling and incapable of realizing double-sided printing due to the fact that the printing ink is not penetrated to the back side.
The further preferred technical scheme is as follows: the dry and wet rubbing fastness of the label tape base material is more than 3.5 grade.
The further preferred technical scheme is as follows: the washing fastness of the trademark tape base material is greater than or equal to 4.0 grade.
In the invention, the dry-wet rubbing fastness and washing fastness of the label tape are superior to those of the common label tape in the market, and the label tape adopts digital ink-jet printing or other printing modes, namely oil-based ink or water-based ink.
