Protective films can be divided into digital product protective films according to their uses. Protective films are mainly used to protect the surface of objects to prevent sharp objects from scratching the surface of another object.

[0003] After searching, the existing Chinese patent announcement number is: CN219467005U, which provides a multi-layer laminating machine for the production of protective films. This patent can effectively extrude multiple films through the mutual cooperation between structures, and cooperate with the laminating machine's own pulling force to make the films fit more tightly, thereby reducing bubbles between the films, and at the same time facilitating the adjustment of the extrusion structure according to the increased thickness of the film.
