- May 09, 2018 -

As a manufacturer of protective film, Hua Li Bao Co. and Ltd have two reasons for the production of protective film residue: 1. factors; 2. in the use process of internal factor protection film, it is easy to cause protective film residual glue because of the inability to choose the membrane with the film professionally.


First, human factor

Many peaple think that protection film is very simple, just a thin plastic film. The irresponsible new person is very easy to have this idea, thinking that any kind of film can meet the needs of the coating protection of their products.


Actually there are still many professional knowledge. For example, the high temperature protection film is needed in the process of high temperature, and it is necessary to keep the chemical residue of the sticker surface without oil and water. Otherwise, it is easy to cause the chemical reaction of the residue and glue, and cause the degumming phenomenon and so on.


Two. Intrinsic factors of glue


According to the residual condition of pressure sensitive adhesive on the protected surface and substrate, the phenomenon of residual film can be divided into 3 situations:


(1) cohesive failure: pressure sensitive adhesive is used on the protected surface and substrate, and the film on the protective film is tarnished.


(2) adhesive damage: there are more rubber residues on the protected surface, and PE protective film can be seen on the adhesive surface.


(3) migration residue: a small amount of pressure-sensitive adhesive remains on the protected surface, and the gloss of the PE protective film is kept well.
