Choose the four measures of glass protective film
Oct 13, 2019
Look: The high definition is a good film, and the inferior film looks like a misty feeling.
Smell: After tearing off the protective layer, the inferior film smells a pungent smell, while the high-grade film uses environmentally-friendly glue, which has basically no taste or a faint glue.
Touch: The high-grade film feels thick and smooth, and the inferior film is very soft and thin, lacking sufficient toughness and easy to wrinkle.
Wipe: You can wipe the surface of the film with a little alcohol or gasoline. Inferior film is easy to fade, and high-grade film is not easy to fade.
