Description

Technical Field

[0001] The present application belongs to the technical field of packaging materials, and in particular relates to a composite bubble film. Background Art

[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, air bead film, bubble cloth, bubble paper, bubble film, bubble film, air cushion film, and air cushion film. It is a chemical product used for packaging filling that is pressure-proof, moisture-proof and shock-proof.

[0003] Japanese Patent Publication No. JP3861657B2 discloses that: in a film having fine voids inside, a layer separated by the voids and a layer composed of the voids are made, and three or more layers of fine bubbles and microbubbles of the fine bubbles are alternately stacked in the thickness direction. The layer is made of a thermoplastic resin (A) and a thermoplastic resin (B) incompatible with the thermoplastic resin (A).

[0004] The above-mentioned bubble film is composed of more than three layers with fine bubbles inside and layers separating them, and each of these layers is alternately stacked in the thickness direction. The obtained bubble film has operability, wrinkle resistance and cushioning properties, but in actual use, there are still some problems, among which the most important is that there is no corresponding fireproof function. During the packaging and transportation process, the product cannot be protected from fire, and improvement is needed. Utility Model Content

[0005] The purpose of this application is to provide a composite bubble film that can solve the above problems.

[0006] The purpose of this application is to provide a composite bubble film, comprising:

[0007] The first film layer;

[0008] The second film layer;

[0009] The bubble film layer is located between the first film layer and the second film layer, wherein the bubble film layer comprises a first bubble film layer and a second bubble film layer which are arranged opposite to each other, and each of the first bubble film layer and the second bubble film layer comprises a film layer body and a plurality of buffer bubbles arranged on the film layer body;

[0010] Wherein, each buffer bubble in the first bubble membrane layer and the second bubble membrane layer is filled with gaseous fire extinguishing medium.

[0011] The above-mentioned composite bubble film is adopted, and the first film layer and the second film layer are arranged to protect the internal bubble film layer. The bubble film layer is located between the first film layer and the second film layer, and plays the main role of buffering and shock absorption. The bubble film layer is composed of two layers. The design of the first bubble film layer and the second bubble film layer makes the bubble film layer have a double buffering effect, absorbing and dispersing the external impact force through the compression and release of air, thereby protecting the internal items from damage and improving the overall protective performance.

[0012] Each buffer bubble is filled with a gas fire extinguishing medium, which has a fire extinguishing function. The gas fire extinguishing medium is composed of five gases: hexafluoropropane (FE-36), heptafluoropropane (FM-200), perfluorohexanone, incinerator gas and carbon dioxide. The gas fire extinguishing medium is an existing technology and can be quickly released when a fire occurs to effectively suppress the spread of the fire. The composite bubble film not only has buffering and protection functions, but also can play a fire extinguishing role in emergency situations, thereby improving overall safety.

[0013] Furthermore, the buffer bubbles on the first bubble membrane layer and the second bubble membrane layer are distributed alternately.

[0014] The buffer bubbles on the first bubble film layer and the second bubble film layer are arranged alternately, which means that the positions of the bubbles on the two layers of bubble films are staggered, so that when the composite bubble film is impacted by external force, the bubbles in different layers can disperse and absorb the impact force, reducing the single-point force situation. The staggered distribution of buffer bubbles also increases the contact area between the bubble film layers, improves the stability of the overall structure, and the bubbles in different layers can support and work together to resist the impact force, which can better protect the internal items.

[0015] Further: Also includes:

[0016] First wear layer;

[0017] Second wear layer;

[0018] Wherein, the first wear-resistant layer is arranged on a side of the first film layer away from the bubble film layer, and the second wear-resistant layer is arranged on a side of the second film layer away from the bubble film layer.

[0019] The first wear-resistant layer is arranged on the side of the first film layer away from the bubble film layer, and is located at the outermost layer of the composite bubble film, which can enhance the wear resistance of the composite bubble film during use and prevent external friction or scratches from damaging the film layer. The second wear-resistant layer corresponds to the first wear-resistant layer and is arranged on the side of the second film layer away from the bubble film layer, also to improve the durability of the composite bubble film. By setting the first film layer and the second film layer, the overall durability of the composite bubble film can be significantly improved, so that it can better cope with friction, scratches and other wear conditions in daily use, effectively protect various fragile, valuable or long-term storage items, ensure that they are not damaged during transportation and storage, and extend their service life.

[0020] Furthermore, the first wear-resistant layer and the second wear-resistant layer are made of nylon material, and the first film layer and the first wear-resistant layer, and the second film layer and the second wear-resistant layer are connected by bonding.

[0021] The first wear-resistant layer and the second wear-resistant layer are both made of nylon, a synthetic material with excellent wear resistance and temperature resistance. The use of nylon material, the first wear-resistant layer and the second wear-resistant layer can significantly improve the durability and service life of the composite bubble film, and effectively resist the damage to the film layer caused by external friction and scratches. At the same time, the first film layer and the first wear-resistant layer, and the second film layer and the second wear-resistant layer are connected by bonding. This connection method not only ensures the close combination between the layers, but also ensures the stability and reliability of the overall structure. The bonding connection makes the interface between the layers smoother and reduces the risk of damage.

[0022] Furthermore, a first waterproof layer is provided on a side of the first wear-resistant layer away from the first film layer;

[0023] A second waterproof layer is provided on the side of the second wear-resistant layer away from the second membrane layer;

[0024] Wherein, the first waterproof layer and the second waterproof layer are both waterproof membrane layers.

[0025] The first waterproof layer is arranged on the side of the first wear-resistant layer away from the first film layer, which can prevent moisture from penetrating from the outside into the composite bubble film, and protect the internal items from being damaged by the humid environment. The first waterproof layer is made of a waterproof film material, which can effectively prevent moisture penetration. The second waterproof layer corresponds to the first waterproof layer, and is arranged on the side of the second wear-resistant layer away from the second film layer. Like the first waterproof layer, both enhance the waterproof performance of the composite bubble film. By respectively arranging waterproof layers on the outside of the first wear-resistant layer and the second wear-resistant layer, the waterproof performance of the composite bubble film can be effectively improved, and the composite bubble film can keep its interior dry in a humid or rainy environment, and protect the internal items from being eroded by moisture.

[0026] Furthermore, the first membrane layer and the second membrane layer are both woven from elastic fiber yarns.

[0027] Elastic fibers have excellent elasticity and resilience, which can provide better protection for composite bubble film against impact and extrusion, and enable the film layer to withstand multiple bending and stretching without being easily damaged. The elastic fibers are interwoven together through weaving to form a stable mesh structure, which enhances the mechanical strength of the film layer and also gives the film layer a certain degree of stretchability and ductility, which can adapt to packaging needs of different shapes and sizes.

[0028] The beneficial effects of this application are:

[0029] 1. The above-mentioned composite bubble film is adopted. The first film layer and the second film layer can protect the internal bubble film layer. The design of the first bubble film layer and the second bubble film layer enables the bubble film layer to have a double buffering effect, absorbing and dispersing the external impact force through the compression and release of air, thereby protecting the internal items from damage and improving the overall protection performance;

[0030] 2. By filling each buffer bubble with a gas fire extinguishing medium, the gas fire extinguishing medium has a fire extinguishing function and can be quickly released when a fire occurs, effectively suppressing the spread of the fire. The composite bubble film can not only have a buffering and protective function, but also play a fire extinguishing role in an emergency, thereby improving overall safety;

[0031] 3. The setting of the first wear-resistant layer and the second wear-resistant layer can significantly improve the durability and service life of the composite bubble film, and effectively resist the damage to the film layer caused by external friction and scratches. The two are connected by bonding. This connection method not only ensures the close combination between the layers, but also ensures the stability and reliability of the overall structure. The bonding connection makes the interface between the layers smoother and reduces the risk of damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The second film layer 200;

[0042] The bubble film layer is located between the first film layer 100 and the second film layer 200. The bubble film layer includes a first bubble film layer 300 and a second bubble film layer 310 that are arranged opposite to each other. The first bubble film layer 300 and the second bubble film layer 310 both include a film layer body 320 and a plurality of buffer bubbles 330 arranged on the film layer body 320.

[0043] Each buffer bubble 330 of the first bubble membrane layer 300 and the second bubble membrane layer 310 is filled with a gaseous fire extinguishing medium 340 .

[0044] In some implementations of the embodiments of the present application, Figure 1As shown, the above-mentioned composite bubble film is used, and the first film layer 100 and the second film layer 200 are arranged to protect the internal bubble film layer. The bubble film layer is located between the first film layer 100 and the second film layer 200, and plays a major role in buffering and shock absorption. The bubble film layer is composed of two layers. The design of the first bubble film layer 300 and the second bubble film layer 310 enables the bubble film layer to have a double buffering effect, absorbing and dispersing external impact force through the compression and release of air, thereby protecting the internal items from damage and improving the overall protective performance.

[0045] Each buffer bubble 330 is filled with a gas fire extinguishing medium 340, which has a fire extinguishing function. The gas fire extinguishing medium 340 is composed of five gases: hexafluoropropane (FE 36), heptafluoropropane (FM 200), perfluorohexanone, incinerator gas and carbon dioxide. The gas fire extinguishing medium 340 is an existing technology and can be quickly released when a fire occurs to effectively suppress the spread of the fire.

[0046] Furthermore, the buffer bubbles 330 on the first bubble film layer 300 and the second bubble film layer 310 are distributed alternately.

[0047] The buffer bubbles 330 on the first bubble film layer 300 and the second bubble film layer 310 are arranged in a staggered manner, which means that the positions of the bubbles on the two layers of bubble films are staggered, so that when the composite bubble film is impacted by external force, the bubbles in different layers can disperse and absorb the impact force, reducing the single-point force situation. The staggered distribution of buffer bubbles 330 also increases the contact area between the bubble film layers, improves the stability of the overall structure, and the bubbles in different layers can support and work together to resist the impact force, thereby better protecting the internal items.
