Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Refer to the instruction manual Figure 1-5 The utility model provides a laser polypropylene transfer film, comprising a film body 1, wherein the film body 1 comprises a base layer 2, wherein a high temperature resistant layer 3, a laser layer 4, a waterproof layer 5 and a flame retardant layer 6 are fixed on the top and bottom of the base layer 2 in sequence from the inside to the outside, wherein the base layer 2, the high temperature resistant layer 3, the laser layer 4, the waterproof layer 5 and the flame retardant layer 6 are coated with a cut resistant layer 7 on the outside, wherein the base layer 2 is a polypropylene film, and the polypropylene film is fixed between two high temperature resistant layers 3;

[0026] Specifically, the cut-resistant layer 7 is a grid line 701, and the grid line 701 is woven from a plurality of transverse fiber filaments 7011 and a plurality of longitudinal fiber filaments 7012, and a plurality of spaces 7013 are formed between the plurality of transverse fiber filaments 7011 and the plurality of longitudinal fiber filaments 7012, and each transverse fiber filament is made of ultra-high molecular weight polyethylene fiber to make the transverse fiber filament cut-resistant, and each longitudinal fiber filament 7012 is made of spandex to make the longitudinal fiber filament 7012 elastic;

[0027] In addition, metal powder 8 is laid on the outer walls of the two flame retardant layers 6 away from the base layer 2, and the metal powder 8 is fixedly bonded to the surface of the flame retardant layer 6 by thermoplastic polyester hot melt adhesive. The metal powder 8 is laid in multiple spaces 7013, so that the surface of the flame retardant layer 6 can be cut-resistant.

[0028] The membrane body 1 is composed of a base layer 2, a high temperature resistant layer 3, a laser layer 4, a waterproof layer 5 and a flame retardant layer 6. The base layer 2 is a polypropylene film. The polypropylene film has the advantages of high physical and mechanical strength, light weight, non-toxicity and moisture resistance. Therefore, the strength of the base layer 2 can be improved. The base layer 2, the high temperature resistant layer 3, the laser layer 4, the waterproof layer 5 and the flame retardant layer 6 are wrapped with a grid line 701. The grid line 701 is woven from a plurality of transverse fiber filaments 7011 and a plurality of longitudinal fiber filaments 7012. Each transverse fiber filament is made of ultra-high molecular weight polyethylene fiber. The ultra-high molecular weight polyethylene fiber is a lightweight, high-strength, wear-resistant, corrosion-resistant, impact-resistant and cut-resistant fiber material. Therefore, the transverse fiber filament can be cut-resistant. Each longitudinal fiber filament 7012 is made of spandex. Spandex is a synthetic fiber with high elongation at break, low modulus and high elastic recovery rate. Therefore, the longitudinal fiber filament 7012 can be made highly elastic, so that the grid line 701 can have cut resistance and high elasticity, and play a cut-resistant role on the outside of the membrane body 1.

[0029] Refer to the instruction manual Figure 1-5 The two high temperature resistant layers 3 are made of glass fiber material to improve the high temperature resistance of the high temperature resistant layer 3.

The two flame-retardant layers 6 include two layers of transparent films 601 fixed up and down, and a cavity 602 is formed between the two transparent films 601. A magnesium hydroxide flame retardant 603 is stored in the cavity 602 to play a flame-retardant role.

[0031] The high temperature resistant layer 3 is made of glass fiber material. The glass fiber has good insulation, heat resistance and corrosion resistance, so it can play a high temperature resistant effect on the outside of the base layer 2. The anti-counterfeiting mark on the laser graphic layer can improve the anti-counterfeiting property of the film body 1, and two layers of transparent film 601 are used as the waterproof layer 5. A magnesium hydroxide flame retardant 603 is placed in the cavity 602 between the two layers of transparent film 601.
