What are the application precautions of self-adhesive labels in special environments (such as high t

The application of self-adhesive labels in special environments (such as high temperature, low temperature, and humidity) requires special attention to the following aspects to ensure the adhesion performance and use effect of the labels:

First, the application of notes in high temperature environment

Choose the right material: In a high temperature environment, the material of the self-adhesive label needs to have good heat resistance. Plastic materials such as polyester (PET) and polypropylene (PP) are good choices because they have better heat resistance.

Choose the right glue: Glue types such as hot melt adhesives and pressure sensitive adhesives perform better at high temperatures and can maintain good adhesion properties.

Control the ambient temperature of labeling: When labeling, the ambient temperature should be controlled within the recommended range of the material as far as possible to avoid excessive glue fluidity caused by excessive temperature, resulting in overflow and other problems.

Avoid long-term exposure to the sun: After labeling, try to avoid long-term exposure to the sun to prevent the label from fading, deformation or glue failure.

Second, the application of low temperature environment precautions

Storage ambient temperature: The storage ambient temperature of the self-adhesive label should not be too low to avoid frostbite of the material, which affects the viscosity and processing performance. It is recommended to place the material in an environment above 15 ° C.

Processing environment temperature: When processing self-adhesive labels in a low temperature environment, it is necessary to ensure that the temperature of the machine equipment, ink and substrate materials reaches the appropriate working temperature to avoid problems such as poor printing and die-cutting flymarks.

Labeling ambient temperature: self-adhesive materials have a suitable labeling temperature range, lower than the temperature will affect the stickiness of the label. Therefore, when labeling in a low temperature environment, it should be ensured that the ambient temperature meets the product requirements.

Low temperature pretreatment: If the temperature of the label material is too low due to transportation or storage conditions, low temperature pretreatment should be carried out before labeling to make the temperature of the material rise and restore the viscosity.

Control labeling pressure: When labeling at low temperature, attention should be paid to controlling the labeling pressure to ensure that the label is fully in contact with the surface of the object to improve the adhesion.

Third, the application of precautions in humid environment

Choose the right material: Some special waterproof self-adhesive materials can cope with wet environment, with good moisture resistance.

Control the storage environment: Store self-adhesive labels in a dry and cool place to avoid label distortion or glue failure caused by damp environment.

Ensure that the labeling surface is dry: Before labeling, ensure that the labeling surface is dry, clean and free of oil stains to improve adhesion.

Use moisture-proof packaging: For stock materials, use moisture-proof paper or film to seal the packaging to prevent the intrusion of damp air.

Control the temperature and humidity of the processing workshop: in the wet season or region, the processing workshop should be equipped with temperature and humidity control equipment to ensure that the temperature and humidity in the workshop is appropriate.

In summary, the application of self-adhesive labels in special environments requires attention to many aspects such as material selection, glue type, ambient temperature control, storage conditions and details in the labeling process. Following these precautions can help ensure the adhesion performance and use effect of self-adhesive labels in special environments.
