1. The problem of insecure paste:
Whether the color or transparent PE protective film is not firmly attached to the protective product, it will fall off during transportation and use;
The big possibility is that the viscosity of the sensitive adhesive used in the production of the protective film product is not enough. Another possibility is that the pressure of the molding machine used by the user when applying the mold is not enough, or the surface of the profile is not clean. Dust or paint, etc., affect the paste effect of sensitive adhesive!
Solution: If this problem occurs, it is necessary to address the cause, take 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 filming, which will avoid such problems.
2. Wings at both ends:
The film performs well in the middle after a period of use, but the two ends are winged. The main reason for this phenomenon is that the protective film is stretched to a large extent during the pasting process with the protected profile, or it is stuck. After the protective film, in the high-temperature environment, unnecessary retraction occurs, and this problem mostly occurs in the products of southern customers.
Solution: In the production process of PE protective film, attention should be paid to the impact of environmental temperature difference on the use of the product. During the pasting process, unnecessary surface stretching must be avoided. The problem of the above two ends being raised is basically solved.
