What are the shortcomings or limitations of self-adhesive coated paper?

Although self-adhesive coated paper is widely used in many fields, there are also some shortcomings or limitations, mainly including the following aspects:

1.the weather resistance is relatively poor

The weather resistance of self-adhesive coated paper is relatively weak, and it is easily affected by environmental factors such as temperature and humidity. Under the conditions of high temperature, high humidity or long lighting, the self-adhesive coated paper may fade, deform or fall off, affecting the beauty and service life of the label.

2.the scratch resistance is insufficient

The surface of self-adhesive coated paper is relatively soft, and the scratch resistance is poor. If it is scratched or worn by hard objects during transportation, handling or use, the pattern and text on the label may be damaged, resulting in blurred or illegible information.

3.the viscosity is relatively weak

The stickiness of self-adhesive coated paper is relatively weak and may not meet the needs of some special applications. In the long-term use or high temperature and humidity environment, the label may decline in viscosity or fall off, affecting the robustness and durability of the label.

4.not waterproof, not oil-proof

Self-adhesive coated paper that has not been specially treated usually does not have waterproof and oil-resistant properties. In a humid or greasy environment, the label may absorb water and become deformed or contaminated with oil, resulting in blurred information or damage to the label. Although the water and oil resistance can be improved by means such as laminating, it will increase the cost and process complexity.

5.easy to tear

The stiffness of self-adhesive coated paper is relatively insufficient and soft, so it may be easy to tear during use. This is especially obvious when the label is required to withstand a certain tension or pressure.

6.scalability can lead to problems

In a dry natural environment, especially in winter, self-adhesive coated paper may expand, resulting in edge collapse or splitting. This will affect the appearance and use of the label.

7.environmental protection

Some self-adhesive coated paper may not meet environmental requirements, and may have a certain impact on the environment during production and treatment. With the improvement of environmental protection awareness, this shortcoming has attracted more and more attention.

In summary, self-adhesive coated paper needs to pay attention to its limitations in weather resistance, scratch resistance, viscosity, water and oil resistance and environmental protection in the application. In the selection and use, it is necessary to comprehensively consider according to the specific application and needs.
