[0030] In order to keep the following description of the embodiments of the present application clear and concise, the present application omits the detailed description of known functions and known components.
[0031] Embodiment one
[0032] Please refer to Figures 1-4 A bubble film with multiple buffer structures is applied in the field of bubble films, and the structure comprises a first bubble film 1, a nested buffer piece and a composite buffer piece.
[0033] The first bubble film 1 serves as the basic layer of the entire bubble film, and the surface thereof is uniformly provided with a plurality of small bubble columns 2. These small bubble columns 2 can deform when subjected to external force, thereby absorbing and dispersing the impact force and playing a preliminary buffering role.
[0034] The nested buffer piece is arranged on the first bubble film 1 to improve the buffering performance of the overall structure. Specifically, the nested buffer piece comprises a second bubble film 3 tightly hot-pressed on the top surface of the first bubble film 1. The surface of the second bubble film 3 is uniformly provided with large bubble columns 4 corresponding to the positions of the small bubble columns 2. In the manufacturing process, the small bubble columns 2 are accurately embedded into the corresponding large bubble columns 4 to form a nested structure. This nested structure not only enhances the overall strength of the bubble film, but also enables the bubble film to more effectively disperse and absorb impact force when subjected to external force, thereby improving the buffering performance.
[0035] In order to further enhance the buffering effect, the present embodiment also sets the regular quadrilateral bubble columns 5 in the gaps between the plurality of large bubble columns 4, which can also deform when subjected to external force, thereby further absorbing and dispersing the impact force.
[0036] The composite buffer is arranged at the bottom of the first bubble film 1, for further improving the buffering performance of the overall structure. Specifically, the composite buffer includes a buffer sheet 6 fixedly arranged at the bottom of the first bubble film 1. The buffer sheet 6 is made of pearl wool material, which has good buffering performance and pressure resistance, and can effectively absorb and disperse the impact force.
[0037] Embodiment Two
[0038] Improvements are made on the basis of Embodiment One:
[0039] A bubble film with multiple buffering structures, which is applied in the field of bubble films, and the structure includes a first bubble film 1, a nested buffer, and a composite buffer:
[0040] The first bubble film 1 serves as the base layer of the entire bubble film, and the surface thereof is uniformly provided with a plurality of small bubble columns 2, which can deform when subjected to external force, thereby absorbing and dispersing the impact force and playing a preliminary buffering role.
[0041] The nested buffer is arranged on the first bubble film 1 to improve the buffering performance of the overall structure. Specifically, the nested buffer includes a second bubble film 3 tightly hot-pressed with the top surface of the first bubble film 1. The surface of the second bubble film 3 is uniformly provided with large bubble columns 4 corresponding to the positions of the small bubble columns 2. In the manufacturing process, the small bubble columns 2 are accurately embedded into the corresponding large bubble columns 4 to form a nested structure. This nested structure not only enhances the overall strength of the bubble film, but also enables the bubble film to more effectively disperse and absorb the impact force when subjected to external force, thereby improving the buffering performance.
[0042] In order to further enhance the buffering effect, the present embodiment also sets the regular quadrilateral bubble columns 5 in the gaps between the plurality of large bubble columns 4, which can also deform when subjected to external force, thereby further absorbing and dispersing the impact force.
[0043] The composite buffer is arranged at the bottom of the first bubble film 1, for further improving the buffering performance of the overall structure. Specifically, the composite buffer includes a buffer sheet 6 fixedly arranged at the bottom of the first bubble film 1. The buffer sheet 6 is made of pearl wool material, which has good buffering performance and pressure resistance, and can effectively absorb and disperse the impact force.
[0044] Please refer to Figure 3The surface of the buffer sheet 6 is covered with an antistatic agent, which is used to prevent static electricity from damaging sensitive electronic components, and to prevent the generation and accumulation of static electricity during the packaging and transportation of sensitive goods, thereby protecting sensitive goods such as electronic components from damage.
[0045] The first bubble film 1 and the second bubble film 3 are both made of linear low-density polyethylene. The linear low-density polyethylene (LLDPE) has a molecular structure that allows it to better resist deformation and rupture under pressure. When packaging heavy or highly sensitive goods, LLDPE bubble film can provide more reliable protection. For example, when packaging small mechanical parts or glass products, LLDPE bubble film can better withstand collisions and extrusions during transportation. The linear structure of the LLDPE molecular chain also makes it more resistant to puncture. If the bubble film may come into contact with sharp objects during use, such as when packaging products with metal parts, LLDPE bubble film can reduce the risk of being punctured and damaged.
[0046] The bubble film with multiple buffer structures designed in the utility model has a working principle based on multi-level and multi-structure buffer design, aiming to effectively absorb and disperse external impact force, thereby protecting the packaged goods from damage. The following is a detailed description of its working principle:
[0047] Basic buffer layer:
[0048] The first bubble film 1 serves as the basic layer of the entire bubble film, and its surface is uniformly provided with a plurality of small bubble columns 2. These small bubble columns 2 can elastically deform when subjected to external force, thereby absorbing and dispersing part of the impact force and playing a preliminary buffering role.
[0049] Nested buffer enhancement:
[0050] The nested buffer piece is composed of a second bubble film 3 that is tightly hot-pressed on the top surface of the first bubble film 1. The surface of the second bubble film 3 is uniformly provided with large bubble columns 4 that correspond one-to-one to the positions of the small bubble columns 2. During manufacturing, the small bubble columns 2 are precisely embedded into the corresponding large bubble columns 4, forming a unique nested structure. This nested structure not only enhances the overall strength of the bubble film, but also allows the bubble film to more effectively disperse and absorb impact force when subjected to external force, thereby significantly improving the buffering performance.
[0051] Gap buffer supplement:
[0052] In the gaps between the multiple large bubble columns 4, there are set square bubble columns 5. These square bubble columns 5 also have elastic deformation ability and can deform when subjected to external force, further absorbing and dispersing impact force, thereby supplementing and enhancing the buffering effect of the nested buffer.
[0053] Bottom composite buffer:
[0054] The composite buffer is composed of a buffer sheet 6 fixedly arranged at the bottom of the first bubble film 1. The buffer sheet 6 is made of pearl wool material, which has good buffering performance and pressure resistance, and can effectively absorb and disperse the remaining impact force, thereby further protecting the packaged articles.
[0055] Anti-static protection:
[0056] In some application scenarios, especially when packaging and transporting sensitive articles such as electronic components, static electricity may cause damage to them. Therefore, a layer of anti-static agent is coated on the surface of the buffer sheet 6 to prevent the generation and accumulation of static electricity, thereby protecting sensitive articles such as electronic components from damage.
[0057] Material selection:
[0058] The first bubble film 1 and the second bubble film 3 are both made of linear low-density polyethylene material with high strength and good puncture resistance. This material not only has good buffering performance, but also better resists deformation and rupture when subjected to pressure, thereby providing more reliable protection.
[0059] In summary, the bubble film of the present application realizes effective absorption and dispersion of external impact force through multi-level and multi-structure buffer design and reasonable material selection, thereby protecting the packaged articles from damage.
[0060] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. In the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
