[0002] In short, PETG is a transparent plastic that can be made into complex-shaped container packaging. It has the advantages of high blister strength, high transparency, high gloss, easy printing, and not easy to fall off. During the winding and unwinding process of PETG film, due to the rapid friction with the guide roller, static electricity will be generated, which can easily cause damage to production equipment. Static electricity can easily absorb dust, resulting in poor production quality.

[0003] In the existing production, a static-eliminating brush is generally used to remove static electricity from PETG film, but it is easy to scratch the surface of the PETG film when in contact with the PETG film, which affects the quality of the PETG film. Therefore, we propose a static-eliminating device for PETG film production. Utility Model Content
