When using EVA film, it's important to be mindful of moisture and dust to prevent any damage. Make sure to avoid contact with colored objects and keep the film sealed in its original packaging. If you have already cut the film into slices, be sure to cover them tightly if you don't plan on using them right away. Moisture can negatively impact the film's adhesion to glass, whereas vacuuming can affect light transmittance. Additionally, the strong adsorption capacity of the EVA film means it can become easily polluted if it comes into contact with colored or dirty objects. So, it's important to handle it with care to ensure optimal performance.
