Description

Technical Field

[0001] This utility model relates to the field of bubble wrap technology, specifically a bubble wrap with high shock absorption performance. Background Technology

[0002] Bubble wrap, also known as bubble paper or bubble wrap, is a common packaging cushioning material. It is made of two layers of polyethylene film, one of which is processed into evenly distributed closed bubbles to trap air, thus providing excellent shock absorption and protection.

[0003] As mentioned above, most existing bubble wrap bags are made of simple two-layer film. When used for shock absorption and protection, they cannot withstand instantaneous impact pressure, causing the bubbles to break and thus failing to provide safe protection for the contents.

[0004] In view of this, this technical solution designs a bubble bag with high shock absorption performance. Utility Model Content

[0005] The purpose of this invention is to provide a bubble bag with high shock absorption performance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bubble bag with high shock absorption performance, comprising a bag body, a bag opening cover on the opening side of the bag body, an adhesive seal on the inner side of the bag opening cover, an internal honeycomb bubble pad on the inner surface of the bag body, and multiple parallel external multi-level arched bubble strips on the outer surface of the bag body. The external multi-level arched bubble strips are provided with a first-level buffer bubble, a second-level buffer bubble, and a third-level buffer bubble in sequence from the outside to the inside, and the first-level buffer bubble is connected to the second-level buffer bubble, and the second-level buffer bubble is connected to the third-level buffer bubble through multiple vertically distributed one-way valves.

[0007] As a further embodiment of this utility model, the one-way valve includes a rubber sealing ring and a cross-shaped opening structure.

[0008] As a further embodiment of this utility model: the external multi-level arched bubble strip, the internal honeycomb bubble pad and the bag body are connected by a one-time molding composite, lamination composite or adhesive composite method.

[0009] As a further embodiment of this utility model: the bag body, the bag opening seal, the external multi-level arched bubble strip, and the internal honeycomb bubble pad are all made of low-density polyethylene material.

[0010] As a further improvement of this invention, an antistatic agent is added to the low-density polyethylene material.

[0011] Compared with the prior art, the beneficial effects of this utility model are: through the dual buffer design of external multi-level arched bubble strips and internal honeycomb bubble pads, the impact resistance and pressure dispersion capabilities are significantly improved; By using a one-way valve to control the gas flow in stages, the bubbles are prevented from breaking due to overpressure, thus extending the service life.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-3 A bubble wrap bag with high shock absorption performance includes a bag body 10; a bag mouth seal 11 is swung on the opening side of the bag body 10, and a straight adhesive seal 12 is provided on the inner side of the end of the bag mouth seal 11. The opening and closing of the bag body 10 is controlled by the adhesion between the adhesive seal 12 and the outer surface of the bag body 10. The inner surface of the bag body 10 is provided with a layer of built-in honeycomb bubble pad 14, which is in direct contact with the items to be loaded. With the help of the distribution structure of the built-in honeycomb bubble pad 14, the impact force can be evenly distributed, and the compressive strength can be further increased. The outer surface of the bag body 10 is provided with multiple external multi-level arched bubble strips 13 arranged in parallel. The corresponding surfaces of the bag body 10 are connected in an arc shape between adjacent external multi-level arched bubble strips 13. The external multi-level arched bubble strips 13 are used to withstand the pressure from the outside, and the internal multi-level arched bubble strips 13 are provided with a multi-layer buffer structure to gradually reduce the impact pressure. Specifically, the external multi-stage arched bubble strip 13 has a first-stage buffer bubble 15, a second-stage buffer bubble 16, and a third-stage buffer bubble 17 arranged sequentially from the outside to the inside. The first-stage buffer bubble 15 and the second-stage buffer bubble 16, as well as the second-stage buffer bubble 16 and the third-stage buffer bubble 17, are connected in one direction through multiple vertically distributed one-way valves 18. That is, by utilizing the push-to-open and close characteristic of the one-way valves 18, when the outer bubble layer cannot withstand the pressure, the one-way valves 18 automatically open due to the pressure threshold, transferring the gas in the forced bubble layer to the inside, thereby relieving the pressure and preventing the bubble layer from being damaged by pressure and causing danger. The one-way valve 18 achieves its one-way liquid discharge function through a rubber sealing ring and a cross-shaped opening. Specifically, the opening of the one-way valve 18 is sealed with rubber, and an internal cross-shaped opening is provided. When external air pressure compresses the valve, the rubber ring expands outward under force, opening the cross-shaped opening and allowing gas to flow out. After the pressure is released, the rubber ring springs back to seal the opening, preventing liquid backflow. The rubber sealing ring is elastic and can effectively seal the opening, while the cross hole design ensures unidirectional gas flow; It should be noted that the one-way valve opens when the air pressure reaches a preset threshold. This preset threshold depends on the design parameters of the bubble bag, such as material elasticity, bubble size, and valve structure. In actual production, it can be adjusted according to the buffering requirements. It is generally determined through experiments or simulations to ensure that it opens before the impact pressure exceeds the bubble's tolerance limit. For example, the preset threshold can be set within the range of 70% to 90% of the compressive strength of the bubble wrap.

[0021] The above is only a brief description of the preset threshold. Details can be set according to actual experiments or simulations, and will not be elaborated here.

[0022] In this embodiment of the utility model, the external multi-level arched bubble strip 13, the internal honeycomb bubble pad 14 and the bag body 10 are bonded together by one-time molding, coating / extrusion, or adhesive bonding. For example, in one-time molding, during the production process, two or more layers of film are directly bonded together by co-extrusion, and bubbles are formed on one of the film layers by vacuum forming, so that the bubble layer and the bag body are naturally a whole, with a firm connection and no risk of delamination.

[0023] In one embodiment of this utility model, the bag body 10, the bag opening seal 11, the external multi-level arched bubble strip 13, and the internal honeycomb bubble pad 14 are all made of low-density polyethylene, which has good elasticity and waterproofness. Preferably, adding an antistatic agent to low-density polyethylene can produce pink-labeled antistatic bubble wrap, which is mainly used for packaging electronic products.

[0024] The adhesive seal 12 uses double-sided tape, and the main component of the tape is acrylic pressure-sensitive adhesive.

[0025] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0026] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
