Chuwi iBook x screen

Hi everyone, I just bought a Chuwi Ubook x and after I removed the protective film I noticed that there is something that looks like a screen protector because I can see a couple of tiny bubbles. I found on Amazon a tempered glass screen protector for this tablet.
My question is: is the screen film that comes with the chuwi made of plastic? And can it be removed without damaging the screen? From what I can see it looks just like a bad quality screen protector

Ubook X has a glass screen and comes with two layers of film: informative/shipping film and protective film.

OK! Thanks for the info. Then I guess
I can replace the protective film with a tempered glass screen protector
