Dry glue material is widely used in the printing industry, the use method is also increasingly mature, the quality of adhesive material is also not improving, of course, the quality of some of the inferior counterfeit, and how to distinguish the quality of the dry glue material?

面材

Surface material

       即表面材料。一般来说，凡是可柔性的材料都可以作为不干胶材料的面料，面材的种类取决于最终的应用和印刷加工工艺。

It is a surface material. Generally speaking, any flexible material can be used as the material of self-adhesive material. The type of surface material depends on the final application and printing process.

面材要能够：

The surface material should be able to:

A. 适应印刷和打印，具有良好的着墨性

A. is suitable for printing and printing, and has good ink penetration.

B. 有足够强度能够接受各种加工

B. has enough strength to be able to accept all kinds of processing

C. 面材的表面光泽和颜色的一致性、密度的均匀性,这决定了不干胶材料吸墨的均匀性和同批标签印品的色差。

The surface gloss and color consistency and density uniformity of C. surface material determine the uniformity of ink absorption and the color difference of the same batch of labels.

表面涂层

Surface coating

       用于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。

It is used to change the surface properties of the surface material. Such as improving the surface tension, changing the color, increasing the protection layer and so on, making it better to accept ink and easy to print, to prevent dirty, increase the adhesion of ink and prevent the printing from falling off.

A.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。

A. surface coating is mainly used for non absorbent materials, such as aluminum foil, aluminized paper and various kinds of thin film materials.

B.涂层强度决定了印刷时是否会产生大量纸粉，是决定印刷质量的重要指标。

The strength of B. coating determines whether a large amount of paper powder will be produced during printing, which is an important index to determine the quality of printing.

涂底层

Bottom layer

       其同表面涂层一样，但是涂布在面材的背面，涂底层的主要目的是：

It is the same as the surface coating, but is coated on the back of the surface. The main purpose of coating the bottom is:

A.保护面材，防止粘合剂渗透

A. protects surface materials to prevent penetration of adhesives

B.增加面料的不透光性;

B. increases the light permeability of the fabric.

C.增加粘合剂同面材间的粘结力;

C. increases the bonding force between the binder and the surface material.

D.防止塑料面材中的增塑剂渗透到粘合剂中，影响其粘合剂性能，导致标签的粘结力降低，标签脱落。

D. prevents the plasticizer in plastic surface from penetrating into the adhesive, affecting its adhesive properties, resulting in the decrease of the adhesive force of the label and the drop of the label.

胶水

glue

       胶水是标签材料和粘结基材之间的媒介，起连结作用。按其特性可以分为永久性和可移除性两种。它有多种配方，适合不同的面材和不同的场合。粘合剂是不干胶材料技术中的最重要的成分，是标签应用技术的关键。

Glue is the medium between label material and adhesive base material, and it acts as a link. According to its characteristics, it can be divided into two types: permanent and removable. It has a variety of formulations, suitable for different surface materials and different occasions. Adhesive is the most important ingredient in the technology of self-adhesive materials, and is the key to the application technology of labels.

底纸

Bottom paper

       底纸的作用是接受离型剂涂布，保护面材背面的粘合剂，支撑面材，使其能够进行模切、排废和在贴标机上贴标。同面材一样，底纸厚度的均匀性和强度指示不仅关系到印刷性能，还是决定模切均匀性和排废时速度与纸边断裂的重要指标。

The function of the base paper is to accept the coating agent, to protect the adhesive on the back of the surface material, to support the surface material, so that it can be die cut, waste and sticker on the labeling machine. As for the same surface material, the uniformity and strength indication of the thickness of the base paper not only relates to the printing performance, but also the important index to determine the uniformity of the die cutting and the breaking of the edge of the paper.
