How to ensure that the thermal label paper is not easy to fall off after pasting?

To ensure that the thermal label paper is not easy to fall off after pasting, you can start from the following aspects:

1. Choose the right type of glue

Common types of glue used for thermal label paper include water glue, hot glue, freezer glue, and removable glue. It is important to choose the right type of glue according to the paste environment and use needs:

Water glue: Suitable for paper surface, the initial viscosity is low but the final viscosity is high, suitable for a variety of substrates (such as plastic, glass and metal containers).

Hot glue: Universal permanent rubber-based adhesive with high initial and final viscosity and excellent performance on many packaging materials.

Freeze adhesive: Low temperature resistant adhesive, suitable for low temperature and refrigeration environment, good performance on paper, carton, film and other substrates.

Removable adhesive: Universal removable acrylic latex, suitable for all temperatures, good initial viscosity, can be cleanly peeled from most applied substrates, no residual adhesive.

2. Ensure that the paste surface is clean and dry

Before attaching thermal labels, ensure that the surface is flat, clean, and dry. You can use sandpaper to remove the oxide layer and convex surface, or clean and wipe with gasoline and other solvents to ensure that the glue can fully contact and adhere to the substrate.

3. Paste correctly

Apply pressure: When pasting, press the label firmly with hand pressure to ensure that the small air gap between the adhesive joints is eliminated, so that the glue can fully play the bonding role.

Avoid bubbles and wrinkles: When attaching the label, align the label and press gently to ensure that the label is tightly fitted to the substrate to avoid bubbles and wrinkles.

4. Select proper storage conditions

The storage conditions of thermal labels also affect the adhesive effect. Should avoid direct sunlight, waterproof, sun protection, high temperature and low temperature. Storage under appropriate temperature and humidity conditions can extend the shelf life of the label and maintain the stickiness of the glue.

5. Use auxiliary fixation

In places where the environment is particularly harsh or the adhesive effect needs to be maintained for a long time, you can consider using transparent tape or other auxiliary fixing measures to enhance the stability of the label.

6. Regular inspection and maintenance

Check the adhesive status of heat-sensitive labels periodically. If it is found that it falls off or loosens, it should be re-pasted or other remedial measures should be taken in time.

In summary, by selecting the appropriate glue type, ensuring that the paste surface is clean and dry, using the correct paste method, selecting the appropriate storage conditions, using auxiliary fixing measures, and regular inspection and maintenance, you can effectively ensure that the thermal label is not easy to fall off after pasting.
