The self-adhesive label paper such as express delivery list has also become an important channel for personal privacy exposure, and the protection of personal privacy has also become a serious problem.

Toilet water eliminates handwriting test on express delivery list

There are two kinds of common express orders. One is quadruple machine printed self-adhesive label paper, which has a rough surface, also known as sub cursor label paper; The other surface is polished, which is also machine-made self-adhesive label paper. The label paper used in the express delivery order usually adopts hot melt adhesive and water emulsion, which are highly adhesive and difficult to tear off. This design is mainly to prevent the label from falling during the transportation of the express delivery, but it is not easy to tear it off easily.

We tested two kinds of label paper respectively. First of all, we sprayed a layer of toilet water on the blue handwriting on the printed matte self-adhesive label paper express sheet, and the handwriting gradually faded after a few seconds, but we could vaguely distinguish the handwriting without any external force; Two minutes later, the blue handwriting where the toilet water was sprayed magically disappeared. Then we sprayed another kind of express bill label with smooth surface, and the handwriting printed on it disappeared instantly.

But after a few minutes, after the matte self-adhesive label paper dried, the sprayed handwriting gradually appeared, but it was obviously more blurred than before spraying dew. It was sprayed again and completely melted, leaving only a layer of light blue paint on the white background. It was really successful. Facts have proved that toilet water can quickly eliminate the handwriting on the express delivery list. Let's try it.
