Description

Technical Field

[0001] This utility model relates to the field of metallized film technology, specifically to a high-temperature resistant metallized polypropylene film. Background Technology

[0002] Metallized polypropylene film exhibits good physical stability, mechanical strength, and airtightness due to its stretched molecular orientation. It also boasts high transparency and gloss, and is tough and wear-resistant, making it the most widely used printing film. However, metallized polypropylene film also has some drawbacks, such as poor heat-sealing properties. Therefore, it is generally used as the outer layer of composite films. For example, when laminated with polyethylene film, its moisture resistance, transparency, strength, stiffness, and printability are significantly improved, making it suitable for packaging dry foods. With continuous social development, the application of metallized polypropylene film is increasing, and its production is also continuously growing.

[0003] Existing metallized films are mostly shipped in rolls. When the rolled metallized film is laid flat for use, the two ends inevitably curl up, making it difficult to use the metallized film flat and affecting the performance. Utility Model Content

[0004] To solve the above-mentioned technical problems, a high-temperature resistant metallized polypropylene film is provided, which solves the problem that in the prior art, metallized films are mostly shipped in rolls, and when the rolled metallized films are laid flat for use, the two ends of the film inevitably curl up, making it difficult to use the metallized film flat and affecting the performance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-temperature resistant metallized polypropylene film, comprising a metallized polypropylene film body, wherein a hollow groove is formed on the bottom end face of the metallized polypropylene film body, and a flat component is placed inside the hollow groove.

[0006] The flattening component includes two symmetrically detachable counterweights disposed inside the hollow groove. The two counterweights are located at both ends of the metallized polypropylene film body. A soft magnetic strip is glued and fixed on the innermost inner wall of the hollow groove, and the counterweights are magnetically attracted to the soft magnetic strip.

[0007] Preferably, a rubber layer is fixed inside the hollow groove, and a positioning groove adapted to the counterweight is formed on the rubber layer.

[0008] Preferably, a heat insulation layer and a flame retardant layer are sequentially sprayed onto the surface of the metallized polypropylene film body. The heat insulation layer is made of polyethylene heat insulation plastic film, and the flame retardant layer is made of flame retardant PC film.

[0009] Compared with the prior art, the advantages of this utility model are as follows: by setting two counterweights, when the rolled metallized polypropylene film body is placed flat, the counterweights can be manually placed into the hollow grooves at both ends of the metallized polypropylene film body, so that the two ends of the metallized polypropylene film body are prevented from curling under the weight of the counterweights, effectively ensuring the flatness of the metallized polypropylene film body and improving the use effect.

[0013] 1. Metallized polypropylene film body; 2. Hollowed-out groove; 3. Counterweight; 4. Soft magnetic strip; 5. Rubber layer; 6. Positioning groove. Detailed Implementation

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0015] Reference Figure 1-2 As shown, a high-temperature resistant metallized polypropylene film includes a metallized polypropylene film body 1, and a hollow groove 2 is formed on the bottom end face of the metallized polypropylene film body 1, and a flat component is placed inside the hollow groove 2.

[0016] The leveling component includes two symmetrically detachable counterweights 3 disposed inside the hollow groove 2, with the two counterweights 3 located at both ends of the metallized polypropylene film body 1.

[0017] With the setting of two counterweights 3, when the rolled metallized polypropylene film body 1 is placed flat, the counterweights 3 can be manually placed into the hollow grooves 2 at both ends of the metallized polypropylene film body 1. This prevents the two ends of the metallized polypropylene film body 1 from curling under the weight of the counterweights 3, effectively ensuring the flatness of the metallized polypropylene film body 1 and improving the use effect.

[0018] Furthermore, referring to Figure 2 As shown, it is worth noting that a soft magnetic strip 4 is glued and fixed on the innermost inner wall of the hollow groove 2, and the counterweight 3 is magnetically attracted to the soft magnetic strip 4.

[0019] With the setting of the soft magnetic strip 4, after the counterweight 3 is placed inside the hollow groove 2, the counterweight 3 and the soft magnetic strip 4 can be tightly attached under the magnetic attraction, which facilitates the fixing of the counterweight 3 at the end of the metallized polypropylene film body 1.

[0020] Furthermore, referring to Figure 2 As shown, it is worth noting that a rubber layer 5 is fixed in the inner side of the hollow groove 2, and a positioning groove 6 adapted to the counterweight 3 is provided on the rubber layer 5.

[0021] By setting the rubber layer 5, the gap inside the hollow groove 2 can be effectively filled after the counterweight 3 is placed inside the hollow groove 2, so as to prevent the middle of the metallized polypropylene film body 1 from collapsing and affecting the flatness. At the same time, the positioning groove 6 on the rubber layer 5 can still be used to position the counterweight 3, so that the counterweight 3 can be horizontally adsorbed on the end of the metallized polypropylene film body 1, so as to prevent the counterweight 3 from being placed crookedly, which would affect the anti-curling effect on the end of the metallized polypropylene film body 1.

[0022] Furthermore, referring to Figure 1 As shown, it is worth noting that a heat insulation layer and a flame retardant layer are sequentially sprayed on the surface of the metallized polypropylene film body 1. The heat insulation layer is made of polyethylene heat insulation plastic film, and the flame retardant layer is made of flame retardant PC film.

[0023] By setting flame-retardant and heat-insulating layers, the metallized polypropylene film body 1 has better flame-retardant and heat-insulating properties, enhances the high-temperature resistance of the metallized polypropylene film body 1, and avoids the occurrence of high-temperature ignition of the metallized polypropylene film body 1.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
