[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] The packaging uses a protective film, such as Figure 1 and Figure 5As shown, the bubble wrap 1 includes several airbag protrusions 2 formed on one side of the bubble wrap 1. The bubble wrap 1 is made of high-pressure polyethylene as the main raw material, with the addition of whitening agents, opening agents and other auxiliary materials. It is formed by extrusion and vacuum forming at a high temperature of about 230 degrees Celsius. Therefore, during vacuum forming, the airbag protrusions 2 are integrally formed on the bubble wrap 1, ensuring the stability of the connection between the airbag protrusions 2 and the bubble wrap 1. Unlike traditional bubble wrap, one side of the airbag protrusions 2 in this application is open to the outside. The side of the bubble wrap 1 away from the airbag protrusions 2 is fixedly connected with an adhesive layer 3. The setting of the adhesive layer 3 allows the bubble wrap 1 to be glued and fixed when wrapped on the item. The bubble wrap 1 is not easy to shift, which improves the protection effect on the item. After the bubble wrap 1 is completely fixed on the item, the area around the airbag protrusions 2 is sealed, maintaining the arched state of the airbag protrusions 2 to achieve buffering against external impacts.

[0023] like Figures 1-4 As shown, a support shell 4 is detachably connected to the bubble wrap 1 via an adhesive layer 3. The support shell 4 has a higher hardness than the bubble wrap 1. An arched shell 5 extending into the airbag protrusion 2 is fixedly connected to the side of the support shell 4 near the bubble wrap 1. The support shell 4 and the arched shell are injection molded from plastic material with a hardness greater than that of high-pressure polyethylene. The arched shell supports the airbag protrusion 2, keeping it in an arched state. The support shell 4 also increases the thickness of the bubble wrap 1, reducing the occurrence of damage during the transportation of the bubble wrap 1. The support shell 4 is made of plastic material, and several deformation grooves 6 are arrayed on both end faces of the support shell 4. The cross-sectional shape of the deformation grooves 6 is triangular. The deformation grooves 6 reduce the overall strength of the support shell 4, allowing the bubble wrap 1 to be rolled up by pulling the support shell 4, in order to meet the transportation requirements of the existing bubble wrap 1. The triangular cross-sectional shape is also designed to facilitate the smooth rolling process of the support shell 4, improving the practicality of this application.

[0024] like Figure 1 As shown, an expansion piece 7 is fixedly connected to one side of the support shell 4. The expansion piece 7 is also integrally formed during the injection molding process of the support shell 4, making the connection between the expansion piece 7 and the support shell 4 more stable. The expansion piece 7 protrudes from the support shell 4, increasing the force application point of the support shell 4. When bubble wrap 1 is needed, pulling the expansion piece 7 can remove the entire support shell 4, and then the bubble wrap 1 can be glued to the outside of the item, improving the safety of transporting the item wrapped in bubble wrap 1.

[0025] like Figures 1-5As shown, the bubble wrap 1 has a protective shell 8 detachably connected to one side where the airbag protrusion 2 is located. The protective shell 8 has several through slots 9 for the airbag protrusion 2 to pass through. Deformation slots 2 and 10 are fixedly connected to both sides of the protective shell 8. The positions of deformation slots 2 and 6 correspond to those of deformation slots 1 and 6. The support shell 4 supports the airbag protrusion 2 to keep it in an arched state, while the protective shell 8 protects the airbag protrusion 2 from friction and breakage. The double protection of the bubble wrap 1 is safer. At the same time, the protective shell 8 is also made of the same plastic material as the support shell 4. On the one hand, the plastic material is lightweight and will not increase the difficulty of transporting the bubble wrap 1. On the other hand, the plastic material can be recycled and reused, reducing the waste of resources.

[0026] like Figures 1-3 As shown, the cross-section of the deformation groove 2 10 is also triangular. Similarly, in order to protect the shell 8 and roll it together with the bubble film 1, and to minimize the impact of the added structure on the bubble film 1 itself, the airbag protrusion 2 is located at the position of the through groove 9, which reduces the material used in the protective shell 8, and also achieves the same protective effect on the airbag protrusion 2, thus maximizing the utilization of resources.

[0027] like Figures 1-5 As shown, an expansion piece 7 is also fixedly connected to one side of the protective shell 8, and a connecting block 11 is fixedly connected to each of the four corners of the protective shell 8. The connecting block 11 is fixedly connected to the bubble wrap 1. The thickness of the connecting block 11 and the protective shell 8 is equal to or greater than the depth of the airbag protrusion 2. Several spikes 12 are fixedly connected to the side of the protective shell 8 near the bubble wrap 1. The height of the spikes 12 is less than the height of the connecting block 11. When the bubble wrap 1 is attached to the item, air bubbles are easily generated in the area where the adhesive layer 3 is set during the pasting process. The generation of air bubbles will affect the bonding strength of the bubble wrap 1. The air bubbles need to be punctured to release the gas. For example, a needle or other sharp object. When the protective shell 8 is pulled out, according to the actual force analysis, after the protective shell 8 is pulled and bent, the bent part will deform towards the bubble wrap 1. At this time, the spikes 12 on the protective shell 8 will puncture the air bubbles generated when the bubble wrap 1 is bonded, so that the gas inside can be released and the bonding strength can be improved.

[0028] like Figures 2-5 As shown, the connecting block 11 can increase the thickness of the protective shell 8, ensuring that the protective shell 8 is higher than the airbag protrusion 2 to achieve the protective effect. The spike 12 is also fixedly connected to the protective shell 8 by injection molding. At the same time, the connecting block 11 can also support the spike 12 so that the spike 12 is not easy to pierce the bubble film 1 during transportation. Even if the spike 12 pierces the bubble film 1 during transportation, the supporting shell 4 can protect the bubble film 1, and the bubble film 1 is not easily damaged, thus achieving stable protection for the bubble film 1.

[0029] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
