[0002] Bubble film is a product made of high-pressure polyethylene as the main raw material, with whitening agent, opening agent and other auxiliary materials added, and extruded and blister-formed into bubbles at a high temperature of about 230 degrees. It is a new type of plastic packaging material with light texture, good transparency, non-toxicity and tastelessness, which can prevent moisture, cushion and keep warm for products. It is also called bubble pad. Since the structure of a single bubble film is relatively simple, in order to manufacture bubble films with different properties, the existing technology combines a single bubble film with pearl cotton to obtain a pearl cotton composite bubble film.

[0003] The utility model patent with the publication number CN219927174U discloses a composite bubble membrane of pearl cotton, comprising: a bubble membrane body, a pearl cotton body arranged above the bubble membrane body, a rubber ring fixed to the lower surface of the outer end of the bubble membrane body, and an outer layer wrapped around the outer side of the bubble membrane body, the pearl cotton body and the rubber ring; it also includes: a waterproof and breathable membrane is arranged on the inner side of the bubble membrane body and the pearl cotton body, and the first through hole and the second through hole are opened at equal intervals inside the bubble membrane body and the pearl cotton body respectively; a rubber strip which is an integrated structure with the rubber ring is arranged at equal intervals on the inner side of the rubber ring; and the outer layer is composed of an anti-ultraviolet film, a ceramic wear-resistant coating layer and an epoxy flame-retardant coating layer.

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0028] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0029] Embodiment 1:

[0030] like Figure 1 As shown, this embodiment provides a pearl cotton composite bubble film, including a composite film body;

[0031] The air holes 1 are provided on the composite membrane body, and there are a plurality of the air holes 1 which are evenly spaced and distributed along the length direction of the composite membrane;

[0032] The substrate 2 is pasted and arranged around the composite membrane body;

[0033] Adhesive 3, arranged on the upper side of substrate 2;

[0034] The release paper 4 is arranged on the upper side of the adhesive 3 .

[0035] In the present technical scheme, the composite membrane body is the main part of the pearl cotton composite bubble membrane. The composite structure makes the composite membrane body have certain flexibility and pressure resistance. The air hole 1 is opened on the composite membrane body. By transferring the gas from one side of the composite membrane body to the other side, the composite membrane body has good air permeability. The uniform spacing distribution of the air holes 1 helps to achieve a more uniform air permeability effect, thereby improving the air permeability of the entire membrane. The substrate 2 is pasted and arranged around the composite membrane body to play a role of reinforcement and support. The adhesive 3 is arranged on the upper side of the substrate 2. The adhesive 3 can be a hot melt adhesive, a double-sided adhesive or other suitable adhesive materials. When the composite membrane body is used to package items, it can be directly passed through the substrate 2 and adhesive 3 are packaged, and there is no need to use additional tape to package the composite film body, which improves the packaging efficiency, saves time, prevents the composite film body from being damaged, and ensures that the composite film can be firmly packaged. The isolation paper 4 is arranged on the upper side of the adhesive 3 to play a protective and isolating role. It can prevent the adhesive 3 from directly contacting the external environment, avoid weakening of viscosity or contamination, and also facilitate the use and storage of the sponge double-sided tape. In this way, the composite film body has good air permeability. At the same time, the composite film body can directly package the items through the substrate 2 and the adhesive 3, and there is no need to use additional tape to package the composite film body, which improves the packaging efficiency, saves time, and ensures that the composite film can be firmly packaged.

[0036] Embodiment 2:

[0037] This embodiment provides a pearl cotton composite bubble film, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] like Figure 2 As shown, in this embodiment, the composite membrane body is optimized to be composed of a pearl cotton layer 5 and a bubble membrane layer 6.

[0039] In the present technical scheme, the composite film body is composed of a pearl cotton layer 5 and a bubble film layer 6. The pearl cotton layer 5 provides a soft protective layer, and the bubble film layer 6 provides the heat insulation and buffering properties of the bubble structure. Such a composite structure has both the softness and pressure resistance of pearl cotton and the heat insulation, sound insulation and buffering properties of bubble film, so that the entire film has multifunctional application value; the pearl cotton composite bubble film, through its unique composite structure and fixing method, realizes the effective combination of the pearl cotton layer 5 and the bubble film layer 6, thereby giving full play to the advantages of both, providing more comprehensive protection and isolation performance, and is suitable for packaging, heat preservation, sound insulation and other application scenarios.

[0040] like Figure 2As shown, in this embodiment, it is optimized that the pearl cotton layer 5 and the bubble film layer 6 are fixed by heat pressing or bonding.

[0041] In the present technical solution, this fixing method ensures the close combination between the pearl cotton layer 5 and the bubble film layer 6, prevents their separation or slippage during use, and also enhances the overall stability and durability of the film. The hot pressing or bonding method can ensure a reliable fixing effect without damaging the original performance of the pearl cotton and bubble film.

[0042] Embodiment 3:

[0043] This embodiment provides a pearl cotton composite bubble film, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] like Figure 2 As shown, in this embodiment, it is optimized that an elastic layer 7 is provided on the back of the bubble film layer 6, an antibacterial layer 8 is provided on the lower side of the elastic layer 7, a flame retardant layer 9 is provided between the pearl cotton layer 5 and the outer sides of the bubble film layer 6, the elastic layer 7 and the antibacterial layer 8, and a waterproof layer 10 is provided on the upper and lower sides of the flame retardant layer 9.

[0045] In the present technical solution, the elastic layer 7 has good elasticity and resilience, can provide additional buffer protection, and reduce the impact of external impact on the wrapped object. The antibacterial layer 8 has the function of inhibiting bacterial growth, and can maintain the hygiene and safety of the wrapped object. The flame retardant layer 9 has the ability to prevent the spread of flames, enhances the fireproof performance of the film, and improves the safety of the wrapped object. The waterproof layer 10 can prevent moisture from penetrating into the film, protecting the wrapped object from the influence of the humid environment.

[0046] like Figure 2 As shown, in this embodiment, the elastic layer 7 is optimized and formed by bonding polyurethane elastic fibers.

[0047] In the present technical solution, the polyurethane elastic fiber has good elasticity and flexibility, and can provide effective buffering and supporting effects. When external forces act on the surface of the film, the elastic layer 7 can absorb part of the impact force and disperse it to the entire surface of the film, reducing the impact on the wrapped object. The presence of the elastic layer 7 can enhance the overall protective performance of the pearl cotton composite bubble film. When encountering a slight impact or extrusion, the elastic layer 7 can effectively reduce the impact of external impact on the wrapped object and protect it from damage. The polyurethane elastic fiber has the characteristics of wear resistance and aging resistance, and can increase the service life of the pearl cotton composite bubble film. The presence of the elastic layer 7 can effectively prevent the deformation or breakage of the film and maintain its long-term stability and durability.

[0048] like Figure 2 As shown, in this embodiment, the flame retardant layer 9 is optimally made of polypropylene material.

[0049] In the present technical solution, polypropylene is a material with high flame retardant properties. When the film surface is subjected to flames or high-temperature heat sources, the flame retardant layer 9 can quickly stop the spread of flames and prevent the fire from further expanding. The presence of the flame retardant layer 9 effectively reduces the possibility of the pearl cotton composite bubble film burning in a fire, reducing the threat of fire to the surrounding environment and objects. This is particularly important for items that need to be packaged or protected using a film, especially for the packaging and transportation of flammable or high-temperature items. The flame retardant layer 9 made of polypropylene flame retardant material can effectively improve the safety of the pearl cotton composite bubble film. Whether in home, commercial or industrial places, this flame retardant property can provide additional safety protection and reduce casualties and property losses caused by fire.

[0050] like Figure 2 As shown, in this embodiment, the antibacterial layer 8 is optimized by adhering a plurality of fiber threads.

[0051] In the present technical scheme, the fiber yarn of the antibacterial layer 8 has antibacterial properties, and can release substances that inhibit bacterial growth or microstructures that produce antibacterial effects. In this way, when the film surface contacts bacteria or microorganisms, the antibacterial layer 8 can effectively inhibit their growth and reproduction, thereby keeping the wrapped object clean and hygienic. In the fields of medical treatment and food, it is very important to prevent cross infection. The use of the pearl cotton composite bubble film with the antibacterial layer 8 can effectively reduce the spread of bacteria on the surface of the packaging material, reduce the risk of cross infection, and protect people's health and safety. The presence of the antibacterial layer 8 can make the pearl cotton composite bubble film have long-term antibacterial properties, thereby keeping the packaged object clean and hygienic for a long time. This is particularly important for some items that need to be stored or transported for a long time, and can effectively extend their shelf life and service life.

[0052] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
