In order to achieve the above object, the utility model provides a following technical scheme: a high barrier biaxially oriented polyethylene film comprising: the novel cutting tool comprises an outer frame, a roller and a polyethylene film, wherein the inner part of the outer frame is rotatably connected with the roller, the surface of the roller is connected with the polyethylene film, a cutting blade is installed at the bottom end of the inner wall of the outer frame, a through hole is formed in the surface of the polyethylene film, and the polyethylene film comprises a polyethylene film base film, a biaxial stretching film and a low-density polyethylene film.
Preferably, the roller rotates along the opening in the outer frame, and the roller is wound and connected with the polyethylene film.
Preferably, the convex strips on the surface of the biaxially oriented film are matched with the grooves on one side of the low-density polyethylene film, and the polyethylene film base film, the biaxially oriented film and the low-density polyethylene film are connected through hot pressing.
Preferably, the two cutting blades are arranged and are symmetrical about the longitudinal central axis of the outer frame, and the cutting blades are made of stainless steel.
Preferably, the through holes are oval in overlook, the through holes are provided with a group, and the group of through holes are uniformly distributed on the transverse axis of the polyethylene film.
Compared with the prior art, the beneficial effects of the utility model are that:
the high-barrier biaxially oriented polyethylene film can be transversely and longitudinally stretched through the inner biaxially oriented film, then the interference of external ultraviolet rays is blocked through the low-density polyethylene film, then the edge end of the polyethylene film is contacted with the cutting blade, and then the polyethylene film is neatly cut through the use of the through hole, so that the cutting end of the polyethylene film cannot be drawn, and the polyethylene film is convenient to use.
