Manufacturers who use protective film know that the most annoying problem of protective film is residual glue. Today, Ava will analyze the causes and solutions of the protective membrane residue in detail. In the use of protective film it is easy to use protective film residue because it is impossible to choose the movie professionally. There are two main reasons:
Human Factor
The purchaser does not know enough about the protective film. The protective film looks like just a thin piece of plastic. They think that any film can meet their surface protection needs. However, there is a lot of professional knowledge involved in this. For example, in the process of use, if the product needs a long time of exposure, then anti-aging and anti-UV protective film should be used. They must be sure to keep the film surface without oil, banana water, and other chemical residues, otherwise, it is easy to cause the chemical reaction of residue and glue, resulting in the de-glue phenomenon. Please find a professional manufacturer and supplier if you don’t know the protective film.
Glue Factors
Based on the residue situation of pressure-sensitive adhesive on the protected surface and substrate, the phenomenon of protective film residue can be divided into the following three conditions:
Why？
1、The glue formula is unsuitable, or the glue quality is poor, resulting in much residual glue and degrading when tearing the protective film.
2、The protective film has no corona or insufficient corona, resulting in the poor adhesion of the adhesive layer to the protective film. Therefore, when tearing the film, the adhesion force between the glue layer and the plate is greater than the adhesion between the glue layer and the original movie, and deg rubber transfer occurs.
3、The viscosity does not match, and the adhesion between the protective film adhesive surface and the product surface is too high so that the glue layer is destroyed, separated from the PE film, and deg rubber transfer
4、The protected surface has a residual solvent that can react with the protective film adhesive layer, making the protective film challenging to tear or disclose.
Solution： If the user has this problem, you can use a clean cloth to dip in a little alcohol and repeatedly wipe the residual glue until the glue is wiped clean. However, it is necessary to pay attention not to be too hard when wiping, as this may affect the cleanliness of the profile products.
If the glue problem is more serious, it is recommended that the supplier be replaced.
