A rubber strip is integrally formed on the top of the sealing strip on the bag body. This invention facilitates a secure sealing operation using strong adhesive, is convenient to use, and brings convenience to the user.

[0004] The existing technical solutions described above have the following drawbacks:

[0005] The bag is sealed with an adhesive structure, which makes it difficult to open once it is glued. Users usually have to tear or cut the bag to take out the contents, causing irreversible damage to the bag structure and making it difficult to open the bag quickly. Utility Model Content

[0006] The purpose of this invention is to provide a shockproof aluminized film bubble bag to solve the defects of an existing colored aluminized film bubble bag based on strong adhesive sealing.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shockproof aluminum-coated bubble bag, including a bag body, the bag body being composed of an inner protective film, a middle bubble film and an outer protective film, wherein the inner protective film, the middle bubble film and the outer protective film are sequentially composited from the inside to the outside;

[0008] The bag body has a bag opening excess material at the bag opening position, and a tear strip is provided on the bag opening excess material through an easy-tear line, and an adhesive layer is provided on the tear strip;

[0009] A tension strip is provided at the body of the bag via an easy-tear line, and the position of the tension strip corresponds to the position of the tension strip.

[0010] Preferably, the intermediate bubble membrane is provided with bubble cavities, and the bubble cavities are arranged in a honeycomb structure.

[0011] Preferably, the bubble chambers are provided with a connecting channel, and adjacent bubble chambers are connected by the connecting channel, which is used to guide the gas to flow slowly under pressure.

[0012] Preferably, the inner protective film, the middle bubble film, and the outer protective film are formed by thermal bonding.

[0013] Preferably, both the inner protective film and the outer protective film are metallized aluminum-plated PET films.

[0014] Preferably, the adhesive layer on the tension strip is provided with an easy-tear protective film, and the outer walls of the tension strip are symmetrically provided with protruding strips at both ends.

[0015] Preferably, the easy-tear line is made of a mechanically indented line of a preset depth, forming an intermittent linear thinning band along the bag body and the remaining material at the bag opening, so as to guide the tearing path when under tension. The structural strength of the easy-tear line is less than the bonding strength between the tensile strip adhesive layer and the tensile strip.

[0016] Preferably, the excess material at the bag opening is folded over and covers the outer wall of the bag and fits the support strip position, and the protruding strip is folded and hidden at the fold between the excess material at the bag opening and the bag body.

[0017] The shockproof aluminized film bubble bag provided by this utility model has the following advantages:

[0018] In the process of using this shockproof aluminum-coated bubble bag, after the items are put into the bag, the protective film of the adhesive layer is torn off and the air inside the bag is squeezed out. Then the remaining material at the bag opening is folded over, so that the pull strip is glued to the support strip through the adhesive layer, thus completing the sealing action of the bag. At this time, the protruding strip is folded and hidden at the folded position of the bag.

[0019] When you need to access the contents of the bag, pull out the protruding strip. By applying force to the protruding strip, the strip and the protruding strip will separate from the bubble wrap through the tear line, thus opening the bubble wrap.

[0020] By setting up a tension strip and a support strip structure, combined with adhesive layer bonding and easy-tear line guidance, users can achieve a firm seal at the bag opening after packing. When taking out items, they can quickly and neatly open the bag by pulling the protruding strip along the easy-tear line without damaging the overall bag body, thus improving unpacking efficiency. The easy-tear line is formed by mechanical indentation, which makes the tearing process proceed stably along the preset path, avoiding uncontrolled damage to the bag body during the sealing tearing process, and improving tearing accuracy and ease of operation.

[0021] The bubble wrap in the middle uses a honeycomb arrangement of bubble chambers with connecting channels between them. Under pressure, it can achieve directional and slow gas release, improving the overall pressure resistance and cushioning performance, thereby increasing the shockproof capability of the bubble bag.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-5 The present invention provides a shockproof aluminized film bubble bag, including a bag body 1. The bag body 1 is composed of an inner protective film 101, a middle bubble film 102 and an outer protective film 103 sequentially laminated from the inside to the outside. Both the inner protective film 101 and the outer protective film 103 are made of metallized aluminized PET film material. This material has excellent heat insulation, oxidation resistance and electromagnetic shielding performance, which can effectively prevent external heat sources or static electricity from affecting the items inside the bag.

[0031] The inner protective film 101, the middle bubble film 102, and the outer protective film 103 are bonded together by thermal bonding to ensure a stable and reliable structure. The thermal bonding process can ensure that the multi-layer film materials are firmly fused at high temperature to form an overall sealed structure, avoiding interlayer peeling or delamination, and improving the durability and long-term stability of the bag body 1.

[0032] In this embodiment, a plurality of bubble cavities 104 are provided on the intermediate bubble membrane 102. Each bubble cavity 104 is filled with air to provide an effective buffer space. The bubble cavities 104 are arranged in a honeycomb structure, which can achieve stress dispersion when subjected to force, prevent local crushing, and enhance compressive strength and ductility.

[0033] A connecting channel 105 is provided between adjacent bubble chambers 104. The connecting channel 105 is a narrow strip or tubular structure that runs through the adjacent chambers. It can guide the internal gas flow during pressure, thereby mitigating impact and reducing instantaneous internal pressure, effectively preventing the failure of a single bubble bursting. The innovative design of the bubble film structure significantly improves the overall pressure resistance and cushioning protection of the bag body 1, enabling the packaging bag to maintain its good shape and ensure the integrity of the contents even under transportation impacts such as multiple drops or heavy object compression.

[0034] Example 2

[0035] This embodiment also includes: a bag opening material 2 is provided at the bag opening position of the bag body 1. The bag opening material 2 is folded over and covers the outer wall of the bag body 1, and is attached to the support strip 4 at the bag body position. A tension strip 3 is provided on the bag opening material 2. The tension strip 3 is provided with an adhesive layer. The surface of the adhesive layer is covered with an easy-tear protective film for removal during use. Protruding strips 5 are symmetrically provided at both ends of the outer wall of the tension strip 3. After folding, the protruding strips 5 are hidden at the folding point between the bag opening material 2 and the bag body 1, which facilitates subsequent opening.

[0036] In this embodiment, a support strip 4 corresponding to the tension strip 3 is provided at the bag body position of the bag body 1. The tension strip 3 and the support strip 4 are bonded together with an adhesive layer to achieve a firm seal at the bag opening. Before the bag opening material 2 is folded over, the user removes the protective film of the adhesive layer and presses the tension strip 3 onto the surface of the support strip 4 to complete the sealing of the bag body 1.

[0037] When the bag body 1 is closed, it can be opened by pulling out the protruding strip 5 and applying force outward, so that the tension strip 3 and the protruding strip 5 are separated from the bag body 1 through the easy-tear line 6, completing a quick and clean opening operation. The easy-tear line 6 is made of mechanical indentation line of preset depth, forming an intermittent linear thinning band on the bag body 1 and the bag opening residue 2, guiding the tearing path. The tearing process proceeds stably along the preset direction, avoiding damage to the structure of the bag body 1.

[0038] To ensure the reliability of the easy-tear effect, the structural strength of the easy-tear line 6 is lower than the bonding strength between the adhesive layer of the tension strip 3 and the tension strip 4, ensuring that when pulled, the tear is preferentially made along the easy-tear line 6, rather than detaching or damaging other areas, thus improving the opening accuracy and ease of operation.

[0039] This utility model, through the structural cooperation of the tension strip 3 and the support strip 4, combined with the adhesive layer and the easy-tear line 6, makes the seal both reliable and firm, and also enables convenient and complete opening operations, improving packaging and unpacking efficiency. The structure of the middle bubble wrap 102 is optimized, adopting a honeycomb arrangement and connecting channel 105 combination, which greatly improves the shockproof performance.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
