How to improve the stickiness of self-adhesive labels on different material surfaces

To improve the stickiness of self-adhesive labels on different material surfaces, it can be considered and improved from the following aspects:

Select the right type of adhesive:

For different material surfaces, the type of adhesive that matches them should be selected. For example, for rough or porous surfaces, viscoses with strong permeability and initial adhesion can be selected; For smooth or hydrophobic surfaces, adhesives with high surface energy need to be selected to ensure good adhesion.

Optimize label design:

The design of the label also affects its stickiness. For example, increasing the edge width of a label can provide a larger adhesive area, thus enhancing viscosity. In addition, avoid using too much ink or coating on the label to reduce the impact on adhesive performance.

Improve the labeling environment:

The temperature, humidity and cleanliness of the labeling environment have an important impact on the stickiness of the self-adhesive label. Ensure that the labelling operation is carried out under the appropriate temperature and humidity conditions, while keeping the labelling surface clean and dry to improve viscosity.

Pretreatment material surface:

For some difficult to adhere to the material, such as polyester, polypropylene, etc., can be pre-treated to improve its viscosity. For example, corona treatment or plasma treatment is used to change the polarity of the material's surface and increase its affinity for viscose.

Use tackifier:

When necessary, you can consider using tackifier to improve the stickiness of the sticker label. Viscosifier can improve the wettability and adhesion of viscose, so that it shows better viscosity on different material surfaces. However, it is necessary to choose the appropriate tackifier and follow the correct use method.

Proper storage label:

The storage conditions of the label will also affect its stickiness. Ensure that labels are stored in a cool, dry, ventilated environment, away from direct sunlight and high temperatures to maintain adhesive properties and stickiness.

In summary, by selecting the appropriate adhesive type, optimizing the label design, improving the labeling environment, pre-treating the material surface, using tackifier and properly storing the label, the stickiness of the self-adhesive label on different material surfaces can be effectively improved. In the practical application, it is necessary to choose the appropriate method to optimize according to the specific situation.
