Toilet paper is something we often touch in our life, but do you know why there are printing and bumps on it?

Make toilet paper tighter

      As you all know, a piece of toilet paper is actually made up of two pieces stacked together. With this embossed uneven design, it can make the two pieces of toilet paper combine more closely. If it is a smooth surface, it is very easy to separate the two pieces and open them as soon as they are used. Then some people will ask why the two pieces should be glued together? In fact, it's just to make it a little thick. If it's too thin, it's not easy to wipe things and it's not easy to break.

Increase softness

       Its rugged design can also maintain its softness, so that the toilet paper will not collapse during transportation or storage, and it will be better flattened, compacted and compacted. It can also make every piece of toilet paper have a little gap between them, and will not become stiff.

Increase friction

        The particle design on the toilet paper can also make the toilet paper have better friction, which can not only prevent slip, but also better remove dirt, and can increase the surface area of the paper, thus increasing its water absorption. For example, the whole roll of toilet paper for public toilets has no embossing design, so it feels slippery and hard to tear, and often can't find the place to tear! Will often stick together, if not hanging down, often need to find the section where the mouth! So the particles and embossing design on toilet paper are very important.
