Embodiment 1
[0021] A processing method for an integrally formed protective film, comprising the following steps:
[0022] The first step, feeding: feed the double-sided adhesive with release paper by rolling, with the adhesive side of the double-sided adhesive facing upward; at the same time, place the release film on the double-sided adhesive and the transparent The glue is fed, and the double-sided adhesive is pressed together with the release film and the transparent glue to form a pressed film;
[0023] The second step, roll cutting: when the pressed film is conveyed, the release film is cut into a rectangle by rolling cutting to form a plurality of rectangular release films. The roll cutting depth of three sides is 6mm, and the other side The rolling cutting depth is 2mm. Cut the three sides of the double-sided tape and correspond to the rectangular side of the release film. Pull it off, and the remaining rectangular release film, double-sided adhesive tape and transparent adhesive ...
