In the use of anti-rust film, if the packaged items have sharp corners, it is very easy to scratch the anti-rust film. To what extent does it affect the anti-rust effect of the anti-rust film? To what extent is there no impact?

In the application of anti-rust film, if the packaged items have sharp corners or protrusions, it is very easy for the film surface to be scratched or damaged, thereby affecting the anti-rust effect. When the surface of the film is cut or punctured, the sealing property and protective atmosphere of the anti-rust film will be disturbed, the evaporation of the anti-rust agent will accelerate its release, and it may even completely fail. The degree and location of damage are directly related to the rust prevention effect. If the area of the scratch or puncture is large, especially if multiple parts of the film are damaged, the anti-rust effect will be significantly reduced, because the anti-rust agent cannot effectively form a protective atmosphere around the packaged item. In addition, if the damage to the film occurs during long-term storage or transportation, the anti-rust agent will be quickly exhausted, thus failing to provide continuous protection for the metal. Relatively speaking, if the film only has minor cracks or scratches and the damaged area is small, the overall anti-rust effect of the film may not be greatly affected. At this point, the anti-rust film can still maintain a certain degree of integrity, and the evaporation of the anti-rust agent and the protective atmosphere can continue to play a role. Therefore, the degree of scratch or puncture directly determines the protective ability of the anti-rust film. For minor damage, the anti-rust effect can be maintained for a period of time, but large-scale damage may lead to the complete failure of the anti-rust effect.
