不干胶材料的结构从表面上看是由三部分组成,即表面材料、粘合剂和底纸,但从制造工艺和保证质量角度上分析,不干胶材料是由七部分组成.
From the surface, the structure of the self-adhesive material is composed of three parts: surface material, adhesive and backing paper. But from the perspective of manufacturing technology and quality assurance, the self-adhesive material is composed of seven parts
表面涂层。目的是为改变面材的表面特性。如改善表面张力、改变颜色、增加保护层等,使其更好地接受油墨和易于打印,达到防止脏污、增加油墨粘合力以及防止印刷图文脱落的目的。表面涂布主要用于非吸收性材料,如铝箔、镀铝纸以及各类薄膜材料。一般纸类材料不需涂布,但特殊面料如热敏纸、热转移纸则要求表面涂布。
Surface coating. The purpose is to change the surface characteristics of the surface material. Such as improving the surface tension, changing the color, increasing the protective layer and so on, to make it better accept the ink and easy to print, to prevent dirt, increase the adhesion of the ink and prevent the printed text from falling off. Surface coating is mainly used for non absorbent materials, such as aluminum foil, aluminized paper and various film materials. General paper materials do not need coating, but special fabrics such as thermal paper, heat transfer paper requires surface coating.
