How to ensure the adhesion of label paper in different environments?

To ensure the adhesion of the label paper in different environments, multiple factors need to be considered, including the selection of label materials, the treatment of the surface to be affixed, the control of environmental conditions, and the correct pasting method. The following are some specific suggestions and measures:

First, choose the right label material

Adhesive type: The adhesive type of the self-adhesive label directly affects its adhesion. Depending on the environment, permanent adhesives or removable adhesives can be selected. Permanent adhesives are suitable for occasions that require long-term adhesion and are not easy to peel off, such as beer and daily chemical labels; Removable adhesives are suitable for applications that require complete stripping without leaving a trace, such as labels on TV screens.

Surface and backing paper characteristics: the smoothness, tension and thickness of the surface material, as well as the density, water absorption and stability of the backing paper, will affect the adhesion of the label. Selecting the appropriate surface and backing paper for the specific application environment can ensure that the label will maintain good adhesion properties under different conditions.

Second, treat the surface of the attached object

Clean surface: The cleanliness of the surface of the attached material is crucial to the adhesion of the label. Before pasting, ensure that the surface of the paste is clean, smooth, and free of oil and water. For pasted surfaces of different materials, different cleaning methods may be required, such as the use of water, alcohol or special cleaning agents.

Surface treatment: For some materials with rough surfaces or difficult adhesion, the surface performance can be improved by corona treatment, coating treatment and other methods, so as to improve the adhesion of the label.

3. Control environmental conditions

Temperature: Temperature is one of the important factors affecting the adhesion of the label. At low temperatures, the stickiness of the label may be reduced; At higher temperatures, the viscosity may increase. Therefore, when attaching labels, ensure that the ambient temperature is moderate and avoid too high or too low temperatures. For labels that require low temperature or high temperature resistance, the corresponding special adhesive should be selected.

Humidity: Humidity also affects label adhesion. In humid environments, labels may wrinkle and fall off. Therefore, when affixing labels, the indoor humidity should be kept appropriate to avoid too humid environment.

Fourth, the correct paste method

Grasp the correct paste steps: When pasting a self-adhesive label, you should follow the steps of "one tear, two stickers, and three presses". First, remove the label from the backing paper; Then, attach the label to the target location; Finally, the label is compacted with your finger or a scraper to ensure that the label is tightly attached to the surface.

Avoid repeated pasting: During the pasting process, avoid repeated pasting of labels. Because every time you open the label, it will cause certain damage to its adhesion. If you must re-attach, make sure that the surface of the attached object is clean and the label is not damaged.

V. Other precautions

Storage environment: The storage environment temperature of the label paper should not be too low to prevent the label paper from becoming non-stick or aging. At the same time, direct sunlight and high temperature environments should be avoided to prevent deterioration of label materials.

Label storage and use: self-adhesive labels should be stored in a cool, dry, ventilated place. Before use, check whether the label is complete and free of damage, and replace it in time if it is damaged.

In summary, the adhesion of label paper in different environments can be ensured by selecting appropriate label materials, treating the surface of the pasted material, controlling environmental conditions and mastering the correct pasting method.
