1.) The plainness of the glass is poor (especially the tempered glass). Make sure the thickness of the inserted film is more than the deformation scale of the two overlapping glasses.

1.) Processing temperature or heal-holding time(keeping that temperature) is not enough.
2.) The best working period for film is within 6 month. Please use the film within the period.
3.) The glass surface is not clean. Please clean the glass surface.
●Self-exposing
