What are the characteristics of hydrosol (water glue) self-adhesive label paper

Hydrosol (water glue) self-adhesive label paper has a series of unique characteristics, which make it perform well in specific application scenarios. The following is a detailed summary of the characteristics of hydrosol self-adhesive label paper:

First, environmental protection and non-toxic

Environmental protection: Hydrosol self-adhesive label paper is mostly made of environmentally friendly and non-toxic materials, which meets the requirements of modern society for environmental protection. This makes it widely used in food, pharmaceuticals and other fields that require high safety standards.

Second, strong viscosity

Low initial viscosity, high final viscosity: The viscosity of the hydrosol self-adhesive label paper may be relatively low when it is first pasted, but over time, its viscosity will gradually increase to achieve a higher final viscosity. This feature helps to ensure that labels remain stable over time.

Third, good temperature resistance

High temperature resistance: Compared with hot melt adhesive, hydrosol self-adhesive label paper has better high temperature resistance. Although the specific temperature range may vary from product to product, most hydrosols can withstand high temperatures below 90 degrees Celsius, and some can even withstand high temperatures of about 150 degrees. This makes it perform well in situations where it is required to withstand certain temperature changes.

Fourth, liquidity and leveling

Good fluidity: The hydrosol self-adhesive label paper shows good fluidity during the coating process, which helps to achieve a uniform gluing effect. At the same time, its leveling property is also good, and it can form a flat and bubble-free paste layer on the surface of the paste.

5. Application restrictions

Poor low temperature labeling performance: Compared with hot melt adhesive, the labeling performance of water-sol self-adhesive label paper may be poor in low temperature environment. If there is slight water or oil stains on the surface of the paste, the viscosity of the hydrosol may be affected, and the problem of dropping or warping the mark may easily occur.

6. Fields of application

Widely used: Because the water-sol self-adhesive label paper has the characteristics of environmental protection, non-toxic, strong viscosity, good temperature resistance, etc., it is widely used in food, drugs, daily chemical products and some industrial supplies with strict environmental protection requirements. These areas have high requirements for the safety and stability of labels, and the hydrosol self-adhesive label paper just meets these needs.

7. Other features

Easy to use: Hydrosol self-adhesive label paper does not need to brush glue, paste and other auxiliary materials, tear off the paste, easy to use.

Strong durability: Choose the appropriate surface material and adhesive according to different applications, and the water-sol self-adhesive label paper can achieve heat resistance, moisture resistance, corrosion resistance, etc., to ensure that the label can maintain a stable paste effect for a long time.

In summary, the self-adhesive label paper of hydrosol (water glue) performs well in terms of environmental protection, viscosity, temperature resistance, and so on, and has good fluidity and leveling. However, there may be some limitations in low temperature labeling performance. In actual applications, you need to select appropriate self-adhesive labels based on specific requirements and scenarios.
