What matters need to be paid attention to during the packaging process of EVA film

The following matters need to be paid attention to during the packaging process of EVA film:

1. Cleanliness: Before packaging, ensure that the EVA film and battery surface are clean and dust-free to avoid dust and impurities from affecting the packaging effect and battery performance.

2. Temperature control: EVA film has certain temperature requirements during the packaging process. Too high or too low temperature may affect the viscosity and curing effect of the film, so the temperature needs to be strictly controlled.

3. Uniform pressure: During the packaging process, it is necessary to ensure that the EVA film is evenly pressed to avoid local over-pressure or under-pressure causing the package to be unstable.

4. Humidity control: The humidity of the packaging environment will also affect the performance of the EVA film. Excessive humidity may cause the film to absorb moisture and affect the bonding effect.

5. Material compatibility: Ensure that the EVA film has good compatibility with materials such as battery sheets and backsheets to avoid packaging failure due to material reaction.

6. Operating specifications: Packaging operations should follow standard procedures to avoid packaging quality problems caused by human factors.

7. Inspection and testing: After the packaging is completed, appearance inspection and performance testing should be carried out to ensure that the packaging quality meets the requirements.

By strictly complying with the above precautions, the success rate of EVA film packaging and the reliability of battery components can be improved.
