Description

Technical Field

[0001] The utility model belongs to the technical field of packaging, and particularly relates to an inflatable packaging film. Background Art

[0002] An inflatable packaging film is a buffer device for packaging in logistics transportation, and is often used for packaging some fragile and valuable items. After the production of the inflatable packaging film, a roller transportation device is required. That is, the roller transportation device has several roller groups, and one side of the inflatable packaging film is clamped between two clamping wheels of each roller group to realize the transportation of the inflatable packaging film. However, since the rollers between the roller groups may have asynchronous rolling speeds, it is easy to tear the partition between the regions through dotted broken lines during transportation, affecting the product quality. Therefore, it is very important to obtain an inflatable packaging film that is not easily broken. Summary of the Utility Model

[0003] To solve at least one of the above technical problems, the utility model provides an inflatable packaging film, including:

[0004] A film main body;

[0005] A plurality of air bags, arranged in the film main body;

[0006] Dotted broken lines, arranged on the film main body, and the dotted broken lines include a plurality of break points penetrating the thickness direction of the film main body and connecting parts between adjacent two break points;

[0007] At least one side of the film main body forms a matching part for conveying, and the dotted broken line extends from the matching part to the opposite side of the matching part;

[0008] The density of the break points near and / or located at the matching part is less than that of the break points of the dotted broken line in the middle part of the film main body.

[0009] The air bags are strip-shaped or ribbon-shaped, and a plurality of inflatable films form partitions, and the dotted broken lines are arranged between adjacent two partitions.

[0010] The density of the break points decreases from the middle part to the side of the matching part.

[0011] The density of the break points of the dotted broken line within the range of the air bag is x, and the density of the break points of the dotted broken line at the matching part is y, and y < x. The density of the dotted broken line changes from the air inlet of the air bag.

[0012] Compared with the prior art, the advantages of the utility model are as follows: The structure of the utility model is simple. Since the density of the break points at the matching part in contact with the rollers is small, during the transmission process, it is not easily torn, ensuring the integrity of the product and improving the product quality.

[0017] In order to enable those skilled in the art to better understand the present utility model and thus more clearly define the scope of protection required by the present utility model, the present utility model will be described in detail below with respect to certain specific embodiments of the present utility model. It should be noted that the following are only some specific embodiments of the concept of the present utility model, and only a part of the embodiments of the present utility model. The specific and direct descriptions of the relevant structures are only for facilitating the understanding of the present utility model, and the specific features do not of course and directly limit the scope of implementation of the present utility model.

[0018] Referring to the attached drawings, the present utility model adopts the following technical solutions. An inflatable packaging film includes:

[0019] Film main body 1;

[0020] A plurality of inflatable airbags 2 disposed within the film main body 1;

[0021] Dotted line 3 disposed on the film main body 1, the dotted line 3 includes a plurality of break points 4 penetrating the thickness direction of the film main body 1 and a connecting portion 5 between adjacent two break points 4;

[0022] At least one side of the film main body ① forms a fitting portion 6 for conveying, and the dotted line 3 extends from the fitting portion 6 to the opposite side of the fitting portion 6;

[0023] The density of the break points 4 of the dotted line 3 near and / or located at the fitting portion 6 is less than that of the break points 4 of the dotted line 3 in the middle of the film main body 1.

[0024] The inflatable airbag 2 is in a strip or strip shape, and a plurality of inflatable films form a partition 7, and the dotted line 3 is disposed between adjacent two partitions 7.

[0025] The density of the break points 4 decreases from the middle to the side of the fitting portion 6. [[ID=I40]] [[ID=I41]]

[0026] [[ID=I42]]Among them, the present utility model can be a strip-shaped packaging film or a dot-shaped inflatable film.

[0027] The density of the break points 4 of the dotted line 3 within the range of the inflatable airbag 2 is x, and the density of the break points 4 of the dotted line 3 at the fitting portion is y, and y < x. The density of the dotted line 3 changes from the inflation port of the inflatable airbag 2.

[0028] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is simple. Since the density of the breakpoints 4 of the mating part 6 that contacts the roller is small, it is not easy to tear during the transmission process, thus ensuring the integrity of the product and increasing the product quality.

[0029] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
