Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bubble film packaging bags, in particular to a bubble film packaging bag. Background Art
[0002] Bubble film packaging bags are used to package some fragile items to cushion the shaking of the items during transportation. Its main structure is that the buffer bubble film is evenly attached to the bag film, and a cavity is formed inside the bag film to hold the items. The buffer bubble film is on the outside of the bag film and contacts the outside world to cushion the objects and prevent the items from being broken during transportation. The problem with the existing technology is that when the existing bubble film packaging bags are loaded with items for transportation, the buffer bubble film often suffers from severe local wear under certain conditions. Since the bubble films at the worn positions are on the same plane, they will rupture at the same time, resulting in the loss of buffering effect in the worn area. Based on the above situation, it is necessary to design a bubble film packaging bag to solve the above problem. Utility Model Content
[0003] The utility model provides a bubble film packaging bag to solve the problem in the prior art that bubble film packaging bags are prone to severe local wear during use, and the buffer bubble film in the worn area is on the same plane, resulting in all bubbles in the worn area being broken, affecting the buffering effect during the transportation of goods.
[0004] The technical problem solved by the present invention is achieved by the following technical solutions:
[0005] A bubble film packaging bag includes a bag film for packaging articles and a buffer bubble film uniformly attached to the bag film. The buffer bubble film uniformly attached to the bag film has at least two different heights, and the two buffer bubble films of different heights are adjacent to each other. The top surfaces of multiple buffer bubble films of the same height jointly form a supporting plane.
[0006] Preferably, the bag body film includes an inner film and an outer film, the buffer bubble film is arranged between the inner film and the outer film, the bottoms of the buffer bubble films of different heights are all attached to the surface of the inner film, and the top of the buffer bubble film with the largest height is attached to the surface of the outer film.
[0007] Preferably, the cross-sectional shape of the buffer bubble film is a polygon that can be fully spread on the bag film with zero gap.
[0008] Preferably, the buffer bubble membrane has two heights, namely a lower bubble membrane and a medium bubble membrane.
[0009] Preferably, the buffer bubble membrane has three heights, namely, a lower bubble membrane, a medium bubble membrane and a higher bubble membrane.
[0010] Preferably, the bag body film and the buffer bubble film are both made of degradable bio-based materials.
[0011] The beneficial effect of the present invention is that the buffer bubble film can form a plurality of different support planes by setting the buffer bubble film to different heights, thereby preventing the worn area from completely losing its buffering effect when the bubble film packaging bag is partially worn.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0023] Reference Figures 1-8 As shown, a bubble film packaging bag includes a bag film 1 for packaging articles and a buffer bubble film 2 uniformly attached to the bag film 1. The buffer bubble film 2 uniformly attached to the bag film 1 has at least two different heights, and the two buffer bubble films 2 with different heights are adjacent, and the top surfaces of multiple buffer bubble films 2 with the same height jointly form a supporting plane.
[0024] Specifically, the existing bubble film packaging bag uses a buffer bubble film 2 of uniform size. When it contacts the outside, the outermost side of the buffer bubble film 2 contacts the outside. When wear occurs, since the buffer bubble films 2 have the same size, multiple buffer bubble films 2 will wear out simultaneously, and the buffering effect of the worn area will be completely lost. The utility model sets the buffer bubble film 2 to different sizes in height, so that when the packaging bag is locally worn, only a part of the buffer bubble film 2 will be damaged, while the buffer bubble film 2 of the other part remains intact, ensuring that the surface still has a certain buffering effect. Its specific structure refers to Figure 1 and Figure 4 Two buffer bubble films 2 of different heights are arranged above the bag film 1, namely a lower bubble film 201 and a medium bubble film 202. A plurality of lower bubble films 201 form a first support plane 6, and a plurality of medium bubble films 202 form a second support plane 5. Figure 4 As shown, since the second supporting surface formed by the medium bubble membrane 202 contacts the outside world, the medium bubble membrane 202 is first worn out, as shown in FIG. Figure 3 and Figure 4 As shown in FIG, part of the middle bubble membrane 202 is worn, while the lower bubble membrane 201 is intact and can still maintain part of the cushioning performance.
[0025] Furthermore, the buffer bubble membrane 2 has three heights, namely, a lower bubble membrane 201, a medium bubble membrane 202 and a higher bubble membrane 203, thereby enabling the buffer bubble membrane 2 to form three different support planes, namely, a first support plane 6 formed by multiple lower bubble membranes 201, a second support plane 5 formed by multiple medium bubble membranes 202 and a third support plane 4 formed by multiple higher bubbles. When wear occurs, the higher bubbles in the third support plane 4 will first wear out. When the higher bubbles in the third support plane 4 rupture and the second support plane 5 contacts the outside, the medium bubble membrane 202 and the lower bubble membrane 201 can still remain intact, and the bag film 1 can still have a certain buffering performance.
[0026] It can be seen that as long as a plurality of buffer bubble films 2 of different heights are provided on the bag body film 1, it can be achieved that when the packaging bag is locally worn, its local buffer bubble films 2 will not be broken at the same time due to being in the same plane, and it can still be guaranteed to have a certain buffering effect. This is the inventive point of the present utility model. Although only two buffer bubble films 2 of different heights and three buffer bubble films 2 of different heights are cited as examples above, it is easy to imagine that the above-mentioned effect can still be achieved by using four or five buffer bubble films 2 of different heights.
[0027] Further, such as Figure 2 As shown, the bag film 1 includes an inner film and an outer film, the buffer bubble film 2 is arranged between the inner film and the outer film, the bottoms of the buffer bubble films 2 of different heights are attached to the surface of the inner film, and the top of the buffer bubble film 2 with the largest height is attached to the surface of the outer film.
[0028] Specifically, in order to prevent the buffer bubble film 2 from direct contact with the outside and easy damage, the bag film 1 is set to a double-layer structure. The bag film 1 includes an outer film and an inner film. The buffer bubble film 2 is arranged between the outer film and the inner film. The outer film is in contact with the outside. When a wear area appears on the outer film, the higher bubble film 203 is exposed to the outside, thereby further realizing the service life of the bubble film packaging bag.
[0029] Furthermore, the cross-sectional shape of the buffer bubble film 2 is a polygon that can be fully spread on the bag film 1 with zero gap.
[0030] Among them, such as Figure 8 As shown, the cross section of the conventional buffer bubble film 2 is circular. There is a certain gap between the circular bubble films on the bag film 1 within a unit area. The gap is mainly formed by the gap 3 generated between adjacent buffer bubble films 2. Figure 8 The gap 3 is mainly formed by four buffer bubble films 2 with circular cross sections. Since there must be gaps 3 between the buffer bubble films 2 with circular cross sections, it is impossible to achieve full coverage on the bag film 1. Full coverage is interpreted as enabling the buffer bubble film 2 to fully cover the bag film 1. The laying area of the buffer bubble film 2 directly affects the buffering effect. Therefore, the larger the coverage area of the buffer bubble film 2 per unit area of the bag film 1, the better the buffering effect. Therefore, preferably, the cross section of the buffer bubble film 2 adopts a polygon to ensure that the buffer bubble film 2 per unit area of the bag film 1 is fully covered, that is, there is no empty gap on the bag film 1. Specifically, the polygon can be as follows Figure 6 The rectangle shown, or Figure 7 The regular hexagon shown in the figure still reserves a certain gap to facilitate observation of the shape of the buffer bubble membrane 2. However, in the actual production process, the adjacent buffer bubble membranes 2 can be fully covered in the case of polygons to ensure the buffering effect.
[0031] Furthermore, the bag body film 1 and the buffer bubble film 2 are both made of degradable bio-based materials, and the use of degradable materials is more environmentally friendly.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
