[0002] PVC stretch film is a special stretch film, which is often used to wrap wires and cables, various finishing rollers, mechanical equipment, hardware accessories, hoses, steel pipes, furniture, building decoration materials, travel sports shoes, non-woven fabrics and other special-shaped product packaging.

A wear-resistant layer 4 is fixedly connected to the top of the moisture-proof layer 3, and the wear-resistant layer 4 improves the wear resistance of the wrapping film". Although the moisture-proof layer 3 can be made of a polyperfluoroethylene propylene film layer to improve the moisture-proof performance, and the wear resistance of the wrapping film can be improved by using the wear-resistant layer 4, it is slightly complicated and two film layers are needed to achieve moisture-proof performance and wear resistance.

[0024] The moisture-proof insulating structure 2 includes a moisture-proof and wear-resistant layer 201, a flame-retardant layer 202, an insulating layer 203, a stretching layer 204 and a reinforcing layer 205. One side of the surface of the sleeve 1 is connected to the moisture-proof and wear-resistant layer 201, one side of the surface of the moisture-proof and wear-resistant layer 201 is connected to the flame-retardant layer 202, one side of the surface of the flame-retardant layer 202 is connected to the insulating layer 203, one side of the surface of the insulating layer 203 is connected to the stretching layer 204, and one side of the surface of the stretching layer 204 is connected to the reinforcing layer 205. When it is necessary to improve the moisture-proof and insulating performance of the PVC wrapping film, fluorinated ethylene propylene copolymer is added to the moisture-proof and wear-resistant layer 201 to increase the P In order to improve the moisture resistance and wear resistance of VC wrapping film, polyvinylidene chloride is added to the flame retardant layer 202 to increase the flame retardancy of PVC wrapping film when exposed to fire, polyimide is added to the insulating layer 203 to increase the insulation and non-conductivity of PVC wrapping film, polypropylene is added to the stretching layer 204 to increase the extensibility of PVC wrapping film, and polyethylene is added to the reinforcing layer 205 to increase the aging resistance and flexibility of PVC wrapping film and prevent breakage at low temperature. Polypropylene and polyethylene are added to PVC wrapping film at the same time, and their advantages and disadvantages can complement each other, thereby increasing the practicality of PVC wrapping film.

[0025] Furthermore, the moisture-proof and wear-resistant layer 201 is a fluorinated ethylene propylene copolymer layer, and the moisture-proof and wear-resistant layer 201 is in contact with the sleeve 1. Through the setting of the moisture-proof and wear-resistant layer 201, when in use, fluorinated ethylene propylene copolymer is added inside the moisture-proof and wear-resistant layer 201, which can make the PVC wrapping film more friction-resistant and moisture-proof at the same time.

[0026] Furthermore, the flame retardant layer 202 is a polyvinylidene chloride layer, and the flame retardant layer 202 is bonded to the moisture-proof and wear-resistant layer 201. Through the setting of the flame retardant layer 202, when in use, polyvinylidene chloride is added to the inside of the flame retardant layer 202. Polyvinylidene chloride has a high melting point and has good flame retardancy. At the same time, it also has the characteristics of corrosion resistance and good air tightness. After adding polyvinylidene chloride, the PVC wrapping film can increase certain flame retardancy, corrosion resistance and air tightness.

[0030] Furthermore, the picking mechanism 3 includes a roller 301, a picking rod 302, an anti-sweat sleeve 303, a middle groove 304 and a placement plate 305. The roller 301 is embedded in the sleeve 1, and the inner side of the sleeve 1 is connected to the picking rod 302. One end of the picking rod 302 is sleeved with the anti-sweat sleeve 303. The inner side of the picking rod 302 is provided with a middle groove 304, and the surface side of the picking rod 302 is connected to the placement plate 305. Through the arrangement of the roller 301, the picking rod 302, the anti-sweat sleeve 303, the middle groove 304 and the placement plate 305, when in use, the worker holds the picking rod 302 with both hands and fixes one end of the PVC wrapping film on the object to be wrapped. The pick-up rod 302 is then pulled, and the sleeve 1 starts to rotate continuously under the action of the roller 301. At this time, the PVC wrapping film can quickly wrap the article. At the same time, the sweat-proof cover 303 set at one end of the pick-up rod 302 can absorb the sweat on the workers' hands when they sweat while wrapping the articles. After wrapping the articles, one end of the placement plate 305 can be aligned with the middle groove 304 inside the pick-up rod 302, and then the pick-up rod 302 can be put down, so that one end of the placement plate 305 is embedded in the middle groove 304 inside the pick-up rod 302, so that the pick-up rod 302 can be placed on the placement plate 305, which is convenient for next use.

[0031] Furthermore, the surface of the anti-sweat cover 303 is a porous structure, and one end of the picking rod 302 passes through the roller 301. Through the arrangement of the anti-sweat cover 303 and the picking rod 302, when in use, the anti-sweat cover 303 can absorb sweat on the workers' hands and prevent the workers' hands from slipping. The picking rod 302 allows the workers to conveniently use PVC wrapping film to wrap items.

[0032] Working principle: first place the sleeve 1. When it is necessary to improve the moisture-proof and insulating properties of the PVC wrapping film, add fluorinated ethylene propylene copolymer in the moisture-proof and wear-resistant layer 201 to increase the moisture-proof and wear-resistant properties of the PVC wrapping film. Add polyvinylidene chloride in the flame-retardant layer 202 to increase the flame retardancy of the PVC wrapping film when exposed to fire. Add polyimide in the insulating layer 203 to increase the insulating and non-conductive properties of the PVC wrapping film. Add polypropylene in the stretching layer 204 to increase the elongation of the PVC wrapping film. Add polyethylene in the reinforcing layer 205 to increase the aging resistance and flexibility of the PVC wrapping film and prevent it from breaking at low temperatures. Adding polypropylene and polyethylene to the PVC wrapping film at the same time can complement each other, which increases the practicality of the PVC wrapping film. When picking up items, the worker holds the picking rod 302 with both hands, fixes one end of the PVC wrapping film on the items to be wrapped, and then pulls the picking rod 302. Under the action of the roller 301, the sleeve 1 starts to rotate continuously. At this time, the PVC wrapping film can quickly wrap the items. At the same time, the sweat-proof cover 303 set at one end of the picking rod 302 can absorb the sweat on the workers' hands if they sweat when they are wrapping the items. After wrapping the items, one end of the placing plate 305 can be aligned with the middle groove 304 inside the picking rod 302, and then the picking rod 302 is put down, so that one end of the placing plate 305 is embedded in the middle groove 304 inside the picking rod 302, so that the picking rod 302 is placed on the placing plate 305, which is convenient for next use. In this way, a moisture-proof PVC wrapping film is completed.
