Have also had bad experiences with the film during lamination: pushed a bit too oblique: The bottom half of the film is wrinkled after lamination and does not stick. This has (Olympia) always still worked out great in my previous films!
These films (Fellowes) not sticking to each other so as my old, but also keep the inserted prior to laminating paper pieces not so well the position: you shift at the slightest movement of the film, so she finally fall into each other during lamination. = (
For my purposes, therefore not be used!
Maybe I've even got a mounting goods, I do not buy anyway at Fellowes!
