Sticker WholesaleAnd we talk about adhesive label paper material quality should be how to identify?
Adhesive label paper materials, such as adhesive materials, pressure-sensitive materials or stickers, are the basic materials for label printing and are mainly used for packaging and decorative printing. The use of adhesive label paper can be divided into adhesive label paper printing, decorative materials, sealing materials and special materials.Sticker WholesaleThe following mainly introduces the printing materials of adhesive label paper. The basic composition of adhesive label paper printing materials. They are mainly composed of surface printing layer, packaging layer and release layer.
Sticker WholesaleIt is said that the self-adhesive label paper material has been widely improved in the paper industry, and its use method is simple and mature. The quality of self-adhesive label paper can be basically improved. The structure of the self-adhesive label material is composed of three parts from the surface, namely, the surface material, the paper and the paper base. Sticker wholesale and everyone to talk about adhesive label paper material quality should be how to identify?
1. Sticker Wholesale-Surface Material: Surface Material is an adhesive that accepts positive printed graphics and mobile phones and is coated on pasted paper. In general, all deformable materials can be purchased as self-adhesive label stock material. The surface material must be able to adapt to printing and printing, have good ink printing, and have the ability to ensure various processing. The poor ink absorption uniformity of the material also determines the color of the label print.
2. Surface coating: used to change the surface characteristics of the surface material. For example, improve the surface tension, change, increase the protective layer and so on. Make the ground easy to absorb and print, to achieve anti-fouling, increase the ability to dry ink to prevent printing. Surface coatings are used for non-absorbent materials such as aluminum foil, aluminized paper and various films. The coating strength of the surface material determines whether a large amount of paper powder will be produced during the printing process, and it is also an important indicator of printing quality.
3. Sticker wholesale-primer coating: the same as the coating, only coated on the back of the surface material. The main purpose of primer coating is:
(1) Protect the material to prevent penetration.
(2) increase the possible invisibility;
(3) Increase the binding force between the material and the surface material;
(4) Prevent the plasticized tackifier of the plasticizer in the plastic material from penetrating into its performance, reduce the force of the label, and the label falls off.
4. Peel coating (silicone coating): Coat a layer of silicone oil on the surface of the base paper. Silicone oil can make the surface concentration of the base paper very low and the surface is very firm.
5. Collocation: One group is the combination of label material and foundation, which plays a major role. According to its characteristics, it can be divided into single type and adaptive type. According to different ground materials and different environments, there are many combinations. Dry adhesive is an important part of the material technology of adhesive label paper, and it is also the key to the label application technology.
6. Base paper: The function of the base paper is to accept the release agent coating, protect the adhesive at the bottom of the surface material, support the surface material, and cut, discharge and label the labeling machine. Like the surface, the uniformity and strength of the base paper thickness are related to the printing performance, and are also important indicators to determine the synchronization of die cutting, waste discharge speed and paper edge breaking speed.
7.Sticker Wholesale-Back coating or back printing: Back coating is a protective coating on the base paper to prevent waste. The correct amount of makeup remover directly affects the peeling force between the label and the base paper, and the peeling force directly affects the cutting speed and machine of the waste product. The peel force also determines the labeling state of the label. It will also affect the glue penetration of the end face of the self-adhesive label paper.
