Method for avoiding degumming of Protective Film for Aluminum

- Dec 18, 2020-

Degumming has become a common phenomenon in protective films and tapes. Of course, this phenomenon is bad. Generally speaking, the quality of the product itself should be too hard, so it is a big problem to pay attention to in production. Now, let us feel what we can do to help us avoid this situation.

Analysis shows that the general reason is that the protective film of the aluminum-plastic panel must be torn off the surface of the profile after the user equipment is constructed. However, the adhesive of the protective film does not follow the protective film, but remains on the contoured product. This is the most reluctant achievement we will see.

It may be that the pressure glue used in the protective film product generally does not meet the regulations, but that is to say, compared with the viscosity, this will cause the protective film product to peel off when the external force is greater than the internal force.

Therefore, the residues on the contour usually make the protective film of the aluminum composite panel unable to peel off effectively. Generally speaking, there are two possibilities. One is the photosensitive glue used in the protective film products of aluminum-plastic panels, and the other is the photosensitive glue not used for the protective film. However, the protective film plays a good role when sticking, but it plays a good role when peeling off. Generally speaking, it is difficult to compare them. Compared with the protective film produced by some illegal protective film manufacturers, this is also the most common problem.

Another possibility is that the material used in the aluminum-plastic plate protective film master tape is too soft, of course, it cannot withstand the tensile force during peeling, so cracking will occur during peeling. Generally speaking, this is a very headache for users.

Therefore, the key is to pay attention to the production of aluminum-plastic panel protective film. In production, we must strengthen the control and adjustment of related factors, solve problems, and help us better accomplish what we must do.
