Because flexo printing belongs to printing ink, water ink or paper when it is easy to cause swelling, after printing localunsmoothness and under the influence of a printing, also let napkin easily cause wrinkles, and swelling of the substrate and exacerbated the tension fluctuation, the overprinter precision fluctuations, it is difficult to produce. The product. Secondly, because the toilet paper wet strength is poor, and a printing plate, easy to loose fiber on paper to produce layout, make the printing paste version, not continuous, more seriously affect the printing quality and yield. Normal tissue paper is made of two or three layers without wrinkle toilet paper by hinges, through flexible printing, the tooth roller and

A simple combination of paper foil roll embossing forming, China napkins are part of this. Today in Europe on the table napkin before printing most of the materials were micro sizing composite, this paper napkin is smooth, wrinkle free, texture and weight, more of a kind of special product is micro plastic composite products, the printing layer in the three layer structure, it has good texture and flexibility. The surface of the product is more beautiful.

Domestic printing manufacturers should strive to change the embossed napkin, pressed into the micro method after glue printing, so as to make a qualitative leap of quality fly napkin napkin. In addition, the napkin should also increase the improvement in material, in order to narrow the gap with foreign products. As far as possible with high purity pulp production base, adding anti wetting agent enough, for the surface roughness and moisture resistant strength can meet the requirements of printing etc..
