Description

Technical Field

[0001] This utility model relates to the field of bubble wrap technology, and in particular to a composite pressure-resistant pearl cotton bubble wrap. Background Technology

[0002] This device belongs to the field of bubble wrap. Bubble wrap is a common cushioning packaging material, made of two layers of polyethylene (PE) film through a heat-sealing process. One layer of film is compressed to form evenly distributed closed bubbles. The bubbles are filled with air, utilizing the elasticity of air to absorb impact energy, thus providing cushioning, shock absorption, and friction protection. To address this, patent CN219928477U discloses a shock-resistant multi-layer bubble wrap, belonging to the field of bubble wrap technology. This utility model discloses a shock-resistant multi-layer bubble wrap, including an outer bubble wrap layer and an inner interlayer bubble wrap layer, which is connected to the outer bubble wrap layer via a slot. To solve the problem that the added structure increases the overall weight and manufacturing cost of the bubble wrap, and that the bubble wrap is at risk of breakage during use, rendering its internal structure unusable, a transparent adhesive layer is filled between the outer bubble wrap layer and the interlayer bubble wrap layer. This transparent adhesive layer bonds and fixes the two bubble wrap layers together, and the solidified transparent adhesive layer protects the inner interlayer bubble wrap layer, preventing sharp objects from puncturing the outer bubble wrap layer and damaging it. The existing technical solutions mentioned above have the following drawbacks: the core problem is that existing bubble wrap is prone to breakage and pearl cotton has insufficient impact resistance, leading to damage to precision instruments or fragile items due to composite stress during transportation. Utility Model Content

[0003] The purpose of this invention is to provide a composite pressure-resistant pearl cotton bubble film to overcome the shortcomings of existing composite pressure-resistant pearl cotton bubble films.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a composite pressure-resistant pearl cotton bubble film, comprising a film body one and a film body two, the lower end of the film body two is provided with the film body two, an adhesive layer is provided between the film body one and the film body two, the upper end of the film body one is provided with a double-layer bubble layer, and the interior of the film body two is provided with limiting strips distributed in a linear array.

[0005] Preferably, the membrane body II has mounting grooves arranged in a linear array inside, and a limiting strip is inserted into the mounting groove. The limiting strip is bonded to the inside of the groove. The mounting groove design enables modular assembly of the limiting strip (optional), which facilitates partial replacement and maintenance and reduces the overall maintenance cost.

[0006] Preferably, the limiting strip is designed with a tough material. When subjected to pressure, the tough limiting strip elastically deforms to absorb impact energy, maintains structural integrity after reset, and extends service life.

[0007] Preferably, the bubble layer has an inner bubble inside and an outer bubble outside the inner bubble. The nested inner / outer bubble design disperses external impact force, with small bubbles absorbing high-frequency vibrations and large bubbles resisting continuous pressure, thereby improving dynamic buffering efficiency.

[0008] Preferably, one surface of the membrane is provided with alternating reinforcing strips. The cross-network of reinforcing strips enhances the puncture resistance of the membrane surface and prevents sharp objects from puncturing the bubble layer, making it particularly suitable for packaging items with sharp edges.

[0009] Preferably, the lower end of the second membrane body is provided with grooves arranged in a linear array. The linear groove structure reduces the weight of the second membrane body and forms a stress guiding channel to avoid the risk of tearing caused by local stress concentration.

[0010] The composite pressure-resistant pearl cotton bubble wrap provided by this utility model has the following advantages: This invention innovatively implements a "tiered energy dissipation-synergistic pressure resistance" protection system. Through the interface design of the adhesive layer between membrane body one (pearl cotton substrate) and membrane body two (reinforced bubble layer), combined with the double-cavity structure of the bubble layer and the linear limiting strip of membrane body two, a three-level energy dissipation mechanism is constructed: The membrane-based pearl cotton matrix disperses large-area static pressure through a network of reinforcing strips; the double-layered bubbles utilize air elasticity to gradually attenuate shock waves, and the outer bubbles still maintain more than 50% of the buffering efficiency after the inner bubble ruptures; the tough limiting strips generate directional deformation under bending stress, consuming longitudinal torsional energy and preventing the protective structure from collapsing. By incorporating a protective structure, this collaborative system offers two disruptive improvements: 1. Dynamic stress adaptive adjustment: The groove structure guides the limiting strip to bend in a specific direction under pressure, so that the membrane body II changes from a homogeneous material to an intelligent variable stiffness structure - maintaining flexibility under low pressure, and the limiting strip forms a skeleton network under high pressure, which significantly improves the critical compressive strength threshold. 2. Innovative fault tolerance mechanism: Through the modular design of the installation slot and physical isolation from the bubble layer, the sealed gas does not leak when a single bubble bursts, avoiding chain failures. The limit strip can be replaced independently. Attached Figure Description

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.

[0014] Example 1 Please see Figure 1-4 The present invention provides a composite pressure-resistant pearl cotton bubble film, comprising a film body 1 and a film body 2 5. The lower end of the film body 1 is provided with the film body 2 5, an adhesive layer 9 is provided between the film body 1 and the film body 2 5, a double-layer bubble layer 2 is provided at the upper end of the film body 1, and a limiting strip 7 distributed in a linear array is provided inside the film body 2 5. The membrane body 2 5 has a linear array of mounting grooves 8 inside. Limiting strips 7 are inserted into the mounting grooves 8. The limiting strips 7 are bonded to the inside of the grooves 4. The design of the mounting grooves 8 enables modular assembly of the limiting strips 7 (optional), which facilitates partial replacement and maintenance and reduces the overall maintenance cost.

[0015] In this embodiment, the internal structure of the membrane body 5 is mainly described, including the position and installation mode of the mounting groove 8 and the optional limiting strip 7 inside the mounting groove 8.

[0016] Example 2 This embodiment also includes: the limiting strip 7 is designed with a tough material. When the tough limiting strip 7 is compressed, it absorbs the impact energy through elastic deformation, maintains the structural integrity after reset, and extends the service life.

[0017] The bubble layer 2 has an inner bubble 6 inside and an outer bubble 10 outside. The nested inner / outer bubble 10 design disperses external impact force, with small bubbles absorbing high-frequency vibrations and large bubbles resisting continuous pressure, thus improving dynamic buffering efficiency.

[0018] In this embodiment, it is mainly explained that the bubble layer 2 is divided into an outer bubble 10 and an inner bubble 6, which provides better double-layer protection.

[0019] Example 3 This embodiment also includes: the surface of the membrane body 1 is provided with alternating reinforcing strips 3, the cross network of reinforcing strips 3 enhances the puncture resistance of the surface of the membrane body 1, prevents sharp objects from puncturing the bubble layer 2, and is especially suitable for packaging items with sharp edges.

[0020] The lower end of the membrane body 2 5 is provided with grooves 4 arranged in a linear array. The linear groove structure reduces the weight of the membrane body 2 5 and forms a stress guiding channel to avoid the risk of tearing caused by local stress concentration.

[0021] In this embodiment, the groove 4 at the lower end of the membrane body 5 can reduce weight and disperse stress concentration, thereby optimizing the protective effect.

[0022] Working principle: The main design features of this device are the double-layered bubble wrap 2 and the limiting strip 7 used to reinforce the toughness of the membrane 5. Compared with previous bubble wrap and pearl cotton, it has a better protective effect, can prevent bending, and increases protection. After one layer of bubble wrap breaks, the other layer provides protection, optimizing the protective effect. This device has a multi-layered protective effect and is highly practical.
