How to improve the viscosity of the sticker label

To improve the stickability of self-adhesive labels, we can start from many aspects, including choosing the appropriate adhesive, optimizing the surface of the object, controlling the environmental conditions and improving the labeling technology. Here are some ways to do it:

First, choose the appropriate adhesive

High-quality adhesive: the use of high-quality adhesive is the key to improve the sticeness of the sticker label. High quality adhesive not only has good viscosity, and good heat resistance, not easy to deteriorate. In the selection, you can consider the composition of the adhesive, the viscous strength and the applicable environment and other factors.

High temperature and humidity resistant adhesive: in the environment of high temperature and high humidity, high temperature and humidity resistant adhesive should be selected to ensure that the viscosity of the label is not affected.

Second, optimize the surface of the pasted object

Clean the surface: before labeling, be sure to clean the surface of the pasting, remove oil, dust and other impurities, to ensure that the adhesive and the surface of the pasting are fully in contact, improve the viscosity.

Surface treatment: according to the material and characteristics of the surface of the object, the appropriate surface treatment. For example, for smooth surfaces, corona treatment can be used to increase surface energy and improve viscosity; For rough surfaces, the stickiness can be improved by coating treatment or increasing the weight of glue.

3. Control environmental conditions

Temperature control: The viscosity of the sticker is greatly affected by temperature. In general, the higher the temperature, the greater the stickiness of the sticker. But too high a temperature may make the adhesive too sticky and damage its performance. Therefore, when using self-adhesive labels, the ambient temperature should be controlled in the appropriate range.

Humidity control: too high or too low humidity will affect the viscosity of the adhesive. In the labeling process, the indoor humidity should be kept appropriate to avoid too wet or dry environment.

Iv. Improve labeling technology

Apply appropriate pressure: when labeling, appropriate pressure should be applied to make the label and the surface of the sticker closely fit, exclude air, and improve viscosity. However, attention should be paid to avoid deformation or damage of the label caused by excessive pressure.

Use of professional tools: Tools such as a suitable compactor or roller can be used to apply pressure to make the labeling process more uniform and precise.

V. Other matters needing attention

Choose the right label material: According to the characteristics of the object and the use environment, choose the right label material is also an important factor to improve the viscosity. For example, for occasions requiring water and oil resistance, label materials with corresponding characteristics should be selected.

Pay attention to the shelf life: self-adhesive labels have a certain shelf life. Tags that exceed their shelf life may experience a decrease in stickiness. Therefore, the shelf life of the label should be checked before use to avoid using expired labels.

To sum up, improving the stickability of self-adhesive labels needs to start from many aspects, including selecting the appropriate adhesive, optimizing the surface of the pasting, controlling the environmental conditions and improving the labeling technology. By considering these factors comprehensively, it can be ensured that the self-adhesive label has good viscosity and stability during use.
