Regardless of whether it is colored or the transparent PE protective film is not firmly attached to the protected product, it will inevitably fall off during transportation and use. The greatest possibility is that the PE protective film product is in production. The viscosity of the sensitive adhesive used is not enough. Another possibility is that the pressure of the compression molding machine used by the user is not enough when performing the stamping, or the surface of the profile is not clean, there is dust or paint, etc., which affects the sticking of the sensitive adhesive. effect!
In other words, when PE protective film is in use, if this problem occurs, it is necessary to address the cause, prescribe the right medicine, replace the sensitive adhesive, increase the pressure of the film, or pay attention to the effective cleaning of the surface of the profile when applying the film. Avoid such problems.
After that, the PE protective film performed well after being used for a period of time, but the two ends of the protective film were winged. The main reason for this phenomenon was that the protective film stretched during the pasting process on the protected profile. To a large extent, or after the protective film is attached, unnecessary shrinkage occurs in a high temperature environment. This problem mostly occurs in the products of southern customers. Therefore, the PE protective film should pay attention to the environmental temperature difference during the production process. The effect of product use, avoid unnecessary surface stretching during the pasting process.
PE protective film means that when the protective film is torn off from the surface of the product, glue is left on the surface of the product. It is not easy to remove and affects the appearance. This must be the last thing users want to see.
This phenomenon occurs because the pressure glue used for PE protective film products is quite inconsistent with the regulations, or because it is too sticky. When the PE protective film products are peeled off, the external tension is greater than the internal stress, and the remaining On the profile. At this time, we must also pay attention to choosing the appropriate pressure glue to meet the actual use effect.
