Generally speaking, the viscosity test of self-adhesive products is divided into three test indexes: instantaneous adhesion, lasting adhesion and peeling strength. Instantaneous adhesion represents the bonding speed of materials and should be tested by initial adhesion tester. For example, if the label is tilted during labeling, the initial adhesion is not strong. The lasting adhesion of self-adhesive products represents the time that self-adhesive products can keep, that is, the lasting adhesion. Some labels often have insufficient adhesion after a long time, which is the result of too fast oxidation and poor adhesion, and it needs to be detected by an adhesion tester. Peeling strength is the difficulty of peeling off the adhesive product after pasting, and it is the most important embodiment of the stickiness of the adhesive product.

To sum up, the viscosity test of the above self-adhesive products must pass three indicators * * *, and it is not enough for a single item to represent only one aspect of viscosity, but it can be controlled by using related equipment according to its own problems.

Self-adhesive, also known as self-adhesive label material, is a composite material with paper, film or special material as fabric, adhesive coated on the back and silicon-coated protective paper as backing paper. There are many coating technologies, which lead to the formation of different grades of self-adhesive materials. At present, the development direction is from traditional roll coating, blade coating to high-pressure tape casting coating, to ensure the uniformity and sensitivity of coating to the greatest extent, to avoid bubbles and pinholes and to ensure the coating quality. However, the casting coating technology is not mature in China, and the traditional roller coating method is mainly used in China. 1. Calendered writing paper and offset paper label
