Synthetic paper takes synthetic resin (such as PP, PE, etc.) as the main raw material, melts the resin through a certain process, extrudes and stretches the resin into a film, and then carries out paper-based processing to make its natural plant fiber have whiteness, opacity and printability. General synthetic paper is divided into two categories: one is fiber synthetic paper, the other is film synthetic paper.
Synthetic paper has excellent printing performance and will not break in the printing process; The surface of synthetic paper has a small concave convex shape, which is conducive to improving opacity and printing adaptability; Synthetic paper has good image reproducibility, clear dot, soft color, stable size and not easy to aging.
Embossed paper is characterized by mechanical embossing or wrinkling, forming concave convex patterns on the surface of paper or paperboard. Embossed paper improves its decorative effect by embossing to make the paper more textured. Many flexible packaging papers are often embossed before or after printing to improve the visual effect of packaging and the value of goods.
Embossing paper embossing can be divided into two types: overprint embossing and non overprint embossing. The so-called overprint embossing is to press the shape of the printed flower into a concave convex shape according to the shape of the printed flower, so as to drum up the pattern and play the role of aesthetic decoration. There is no set of relief, that is, there is no direct relationship between relief patterns and printed patterns, and there are a variety of relief patterns. Such as: cloth pattern, twill pattern, needle mesh pattern, skin pattern, hemp pattern, etc.
