Some protective films need to be isolated from the outside world when in use. This can be easily done with adhesive tape; unless some protective film surfaces have special materials themselves, so simple maintenance is sufficient.
When dust is found on the surface of the protective film, do not wash it with water, otherwise it will affect its adhesion, just treat it with a dry paper towel. Under normal circumstances, oil stains are the biggest opponents of protective films. Once the oil stains are occupied, not only will the protective film lose its material, but also it cannot protect the items. Therefore, oil pollution must be absolutely prohibited.https://www.pe-protectionfilm.com/
