Stretch-proof polyethylene film

The utility model relates to the technical field of plastic films, in particular to a stretch-proof polyethylene film which comprises a negative Poisson's ratio grid film, a first adhesive layer, a second adhesive layer, a first low-density polyethylene film and a second low-density polyethylene film. The warp film strips and the weft film strips are in hot melting connection to form a swastika shape, the upper surface of the first low-density polyethylene film is in hot bonding with a stain-resistant and scratch-resistant film, the lower surface of the second low-density polyethylene film is coated with a PE laminating glue layer, and the lower surface of the PE laminating glue layer is bonded with release paper. The tensile expansion characteristic of the negative Poisson's ratio grid film is utilized, the shear modulus, the anti-notch performance, the anti-fracture performance and the resilience toughness of the film are improved, the manufacturing process is simple, surface protection is carried out throu
