Have only five films. One long side of the laminating film is closed and the other three sides. The laminating film is strong enough in itself, so that no wrinkles during lamination occurred. The film did not look so that they quickly electrically charged and so may attract dust. I had no lint trapped after lamination without having embarrassing previously removed any lint off the table. A film was as good as the other. Although the borrowed laminator can officially only films to 80 mic laminating it went well with the purchased 100 mic. The review of the films is after lamination better than a transparent envelope. (250 grams per square meter) Since I have taken stronger paper, I can not judge whether the film is also in simple paper in itself as stable after lamination. Subsequent cutting with a conventional scissors went smoothly (no kinking or cracking). Just to round the corners (radius 3 mm) much me something difficult.
