Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of packaging films for steamed corn, and particularly relates to a cast polypropylene special packaging film for steamed corn. Background Art
[0002] Cast polypropylene film is a polypropylene film produced by the casting process. This film also has good heat sealability. The thickness of the cooking-grade CPP film is generally between 60 and 80 μm, and it can withstand high-temperature cooking at 121°C for 30 minutes, has good oil resistance, airtightness, and high heat seal strength. Generally, the inner layer of meat packaging uses cooking-grade CPP film, and at the same time, polypropylene film can also be used for packaging after steaming corn; however, since the surface of the polypropylene film specially used for packaging steamed corn does not have good opening, and only a section of film is needed for each corn packaging, it is relatively inconvenient to tear the wound-up film. If tools such as scissors are used, it is more troublesome. For this reason, we propose a cast polypropylene special packaging film for steamed corn. Content of the Utility Model
[0003] Aiming at the problems in the prior art, the utility model provides a cast polypropylene special packaging film for steamed corn.
[0004] The technical solution adopted by the utility model to solve its technical problems is a cast polypropylene special packaging film for steamed corn, including a film main body. Grooves for tearing are opened on both the top surface and the bottom surface of the film main body, and there are multiple groups of grooves. Concave holes corresponding to the grooves are opened on both side end surfaces of the outer periphery of the film main body, and there are multiple groups of concave holes.
[0005] Sticking strips for tensioning are bonded to both the top surface and the bottom surface of the film main body, and there are multiple groups of sticking strips. Anti-slip patterns are integrally formed on the outer peripheral surface of the sticking strips.
[0006] By adopting the above technical solution, when using the polypropylene film to package the steamed corn, the concave holes on both side end surfaces of the outer periphery of the film main body and the grooves on the top surface and the bottom surface cooperate with each other, which is convenient for tearing the film main body, so as to facilitate the use when packaging the steamed corn, and at the same time, it is more convenient to tear.
[0007] When it is necessary to tear the film to package the corn, the sticking strips bonded to the outer periphery of the film main body can improve the strength of the film main body, thereby reducing the situation of breakage when the user tears the film main body by hand, enabling the user to use the film main body more stably and conveniently, and packaging the corn. The anti-slip patterns on the surface of the sticking strips can improve the stability when the user takes the sticking strips, thus making it more convenient to tear the film main body.
[0008] Specifically, vertical holes for assisting in tearing are formed on the bottom surface inside the groove, and there are multiple groups of vertical holes.
[0009] By adopting the above technical solution, multiple groups of vertical holes are evenly distributed on the bottom side of the concave hole, making it more convenient to tear the film body.
[0010] Specifically, both the groove and the concave hole are in a V-shaped structure.
[0011] By adopting the above technical solution, it is more convenient to tear the V-shaped groove and concave hole.
[0012] Specifically, multiple groups of the grooves and the concave holes are evenly distributed on the outer peripheral surface of the film body.
[0013] By adopting the above technical solution, multiple groups of grooves and concave holes correspond to each other and are evenly distributed on the surface of the film body. At the same time, the distance between each group of grooves is just convenient for packaging one corn. When the user uses the film body to package the corn, they only need to tear along the groove at the corresponding position.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] 1. Through the design of the groove and the concave hole in the technical solution of the present application, when using the polypropylene film to package the cooked corn, the concave holes at both ends of the outer periphery of the film body and the grooves on the top surface and the bottom surface cooperate with each other, which is convenient for tearing the film body, so it is convenient to use when packaging the cooked corn, and it is more convenient to tear at the same time.
[0016] 2. Through the design of the sticker and the anti-slip pattern in the technical solution of the present application, when it is necessary to tear the film to package the corn, the sticker adhered to the outer periphery of the film body can improve the strength of the film body, thereby reducing the situation of breakage when the user tears the film body by hand, enabling the user to use the film body more stably and conveniently, and packaging the corn. The anti-slip pattern on the surface of the sticker can improve the stability when the user picks up the sticker, thus making it more convenient to tear the film body.

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.
[0023] Please refer to Figures 1-3 , an embodiment of the present utility model provides a technical solution: a cast polypropylene special film for cooking corn packaging, including a film main body 1. Grooves 2 for tearing are provided on both the top surface and the bottom surface of the film main body 1, and there are multiple groups of grooves 2. Concave holes 3 corresponding to the grooves 2 are provided on both side end surfaces of the outer periphery of the film main body 1, and there are multiple groups of concave holes 3; Sticker strips 5 for tensioning are bonded to both the top surface and the bottom surface of the film main body 1, and there are multiple groups of sticker strips 5. An anti-slip pattern 6 is integrally formed on the outer peripheral surface of the sticker strip 5.
[0024] During use, when using the polypropylene film to package the cooked corn, the concave holes 3 on both side ends of the outer periphery of the film main body 1 and the grooves 2 on the top surface and the bottom surface cooperate with each other, which is convenient for tearing the film main body 1, so as to facilitate the use when packaging the cooked corn, and at the same time, it is more convenient to tear;
[0025] When it is necessary to tear the film to package the corn, the sticker strips 5 bonded to the outer periphery of the film main body 1 can improve the strength of the film main body 1, thereby reducing the situation of breakage when the user tears the film main body 1 by hand, so that the user can use the film main body 1 more stably and conveniently, and package the corn. The anti-slip pattern 6 on the surface of the sticker strip 5 can improve the stability when the user picks up the sticker strip 5, so as to more conveniently tear the film main body 1.
[0026] Such as Figure 1 , Figure 2 and Figure 3 As shown in
[0027] During use, multiple groups of vertical holes 4 are evenly distributed on the bottom side of the concave holes 3, so that the film main body 1 can be torn more conveniently.
[0028] Such as Figure 1 , Figure 2 and Figure 3 As shown in
[0029] During use, the grooves 2 and the concave holes 3 with a V-shaped structure are more convenient to tear.
[0030] Such asFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , multiple groups of grooves 2 and concave holes 3 are evenly distributed on the outer peripheral surface of the film body 1.
