Because users are not professional when choosing and applying protective
films, the protective film residue can be caused easily. Main reasons are two
1, Human factors
At the first glace, protective film is very simple product, which is just a piece
of thin plastic film. Ii is easy for irresponsible new users to have this thought.
They think any kind of protective film is suitable for and can provide protection
to their products.
But they couldn’t know that there is a lot professional knowledge about
protective film. For example, if the product with protective film will go through
process under high temperature, then high temperature resistant protective film
should be used. Before applying the film, the surface of substrates should be
without grease, banana oil or other chemical residue, otherwise these chemical
residue will set off a chemical reaction with the glue and cause glue residue.
2, Internal factors of glue
According to the residue of pressure sensitive glue on surfaces of protected
substrate and base film, there are three circumstances of protective film residue.
One. Poor glue cohesion: There is glue residue on both the protected substrates
and base film. And the side of protective film with glue coating becomes tarnished.
Two. Weak bonding between glue and base film. Surface of protected substrate
is with a lot of glue residue, while the base film can be seen on the side of pe
protective film with glue coating.
Three. Migrating residue: The surface of protected substrate is with a little
pressure sensitive adhesive residue, while the side of protective film with glue
coating is still with good gloss.
