[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0018] Referring to Figures 1-3 A kind of anti-tearing roll film, including roll film body 1, the both sides of roll film body 1 are corrugated, and multiple auxiliary grooves 12 are provided equidistantly at one end of roll film body 1, auxiliary bump 11 is installed between adjacent auxiliary grooves 12 at one end of roll film body 1, and roll film body 1 includes polypropylene layer 101, auxiliary layer 102 is arranged on the both sides of polypropylene layer 101, auxiliary layer 102 one side is provided with polyester fiber layer 103, and auxiliary coating is coated on the one side of polyester fiber layer 103.

[0019] Meanwhile, two auxiliary layers 102 are bonded on the both sides of polypropylene layer 101 by glue, and the material of auxiliary layer is polyethylene, which is a common plastic material, with good flexibility, low temperature resistance and chemical stability. Polypropylene layer can provide basic flexibility and certain tensile resistance for roll film, so that roll film can withstand a certain degree of external force pulling without being easily broken.

[0020] Polyester fiber has high strength, high rigidity and good heat resistance, chemical resistance, and polyester fiber layer can provide higher tensile strength and dimensional stability for roll film, enhance the mechanical properties of roll film, so that it can withstand greater external force without being easily deformed or damaged.

[0021] And, polyester fiber layer 103 is bonded on one side of auxiliary layer 102 by glue.

[0022] And, the cross section of auxiliary bump 11 and auxiliary groove 12 is oval, and auxiliary bump 11 and auxiliary groove 12 are staggered.

[0023] Further, auxiliary groove 12 inner wall is coated with auxiliary coating.

[0024] Meanwhile, the material of the auxiliary coating is nano-silica.

[0025] In the embodiment, the two sides of the film body 1 are set as a wavy structure, which can effectively disperse stress, avoid local stress concentration, and improve the tear resistance of the film.

[0026] Meanwhile, the auxiliary grooves 12 and the auxiliary blocks 11 can further enhance the tear resistance of the film.

[0027] In the embodiment, the two sides of the film body 1 are set as a wavy structure, which can effectively disperse stress, avoid local stress concentration, and improve the tear resistance of the film.
