Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper, in particular to an anti-static plastic-substitute packaging bag. Background Art

[0002] Static electricity is generated during the long-term friction of electronic components in the packaging bag. When the static electricity accumulates to a certain amount, it may damage the electronic components. In order to prevent static electricity from damaging electronic components, effective anti-static measures need to be taken. At the same time, with the continuous development of the packaging industry, the environmental protection requirements for packaging materials for electronic components are getting higher and higher. Traditional plastic packaging materials are difficult to degrade in the natural environment. After long-term accumulation, they will cause serious pollution and damage to the soil and water sources. Therefore, people have developed degradable materials such as plastic substitute paper to replace traditional plastic packaging materials. Plastic substitute paper is usually made of degradable materials, such as paper, biodegradable materials or renewable resources, which can be naturally degraded in a short time and will not cause long-term pollution and damage to the environment.

[0003] Based on the above situation, a patent with publication number CN115723407A is a packaging bag layer material, which belongs to the technical field of electronic device packaging materials. The packaging bag layer material includes a polyurethane outer layer, a polyurethane aluminum-plated composite layer and a PE composite layer from the outside to the inside. The polyurethane aluminum-plated composite layer includes a polyurethane inner layer and a vacuum aluminum-plated film, wherein the vacuum aluminum-plated film is connected to the polyurethane outer layer, and both the polyurethane outer layer and the polyurethane inner layer are degradable; a plurality of through holes penetrating to the polyurethane inner layer are formed in the PE composite layer. The above-mentioned layer material adopts the design of a polyurethane outer layer, a polyurethane aluminum-plated composite layer and a PE composite layer, wherein the polyurethane outer layer and the polyurethane inner layer both have degradable characteristics, so that the packaging bag made of the above-mentioned material layers has good degradability, which helps to reduce environmental pollution and waste of resources.

[0004] However, in response to the special needs of electronic device packaging, the packaging bags made of the above-mentioned layer materials have insufficient buffering and anti-static functions. Although the polyurethane aluminum-plated composite layer contains a vacuum aluminum-plated film, which may help conductivity to a certain extent, it is not enough to provide sufficient electrostatic protection, especially for electronic devices that are sensitive to static electricity. At the same time, the lack of buffer components in the structure makes it impossible to guarantee the safety and reliability of electronic devices during transportation and use.

DETAILED DESCRIPTION

[0019] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. The implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0020] like Figures 1 to 3As shown, an antistatic plastic substitute packaging bag comprises a packaging bag main body 1, wherein the packaging bag main body 1 is provided with a base paper layer 15, and the packaging bag main body 1 is provided with an open end 4. The base paper layer 15 is provided with a second bubble film layer 16, an inner waterproof layer 17 and an inner antistatic layer 18 in sequence along the inner side of the packaging bag, and the base paper layer 15 is provided with a first bubble film layer 14, a reinforcement layer 13 and an outer waterproof layer 12 in sequence along the outer side of the packaging bag, a hydrophobic layer 11 is provided on the outer side of the outer waterproof layer 12, and the packaging bag main body 1 is provided with an open end 4 and a heat sealing layer 19, and the heat sealing layer 19 covers the end positions of the second bubble film layer 16, the inner waterproof layer 17 and the inner antistatic layer 18.

[0021] The packaging bag of the utility model has good environmental protection. The base paper layer 15, the second bubble film layer 16, the first bubble film layer 14, the outer waterproof layer 12 and the inner waterproof layer 17 are all made of degradable materials, so that the packaging bag body 1 can be naturally decomposed or degraded into harmless substances through a specific treatment method. Compared with general plastic packaging bags, it can effectively reduce pollution to the environment. Through the cooperation of the second bubble film layer 16 and the first bubble film layer 14, the cushioning protection of the packaging bag to electronic components can be increased. The second bubble film layer 16 provides denser second cushioning bubbles 161, which can more effectively disperse and absorb impact force, thereby reducing the risk of damage to electronic components. The larger first bubble film layer 14 The buffer bubble 141 can provide an additional protective layer for the entire packaging bag and electronic components, thereby further protecting the electronic components. The setting of the inner antistatic layer 18 can effectively prevent the generation and accumulation of static electricity, and protect the electronic components from damage caused by electrostatic discharge. The setting of the outer waterproof layer 12 and the hydrophobic layer 11 enhances the waterproof performance of the packaging bag. An outer waterproof layer 12 is provided on the outer side 3 of the packaging bag body 1, and a hydrophobic layer 11 is coated on its outer surface, which effectively prevents moisture from penetrating into the interior of the packaging bag, thereby providing good protection for the electronic components. By providing a reinforcing layer 13 between the first bubble film layer 14 and the outer waterproof layer 12, the strength and durability of the packaging bag body 1 are significantly improved.

[0022] When constructing the utility model, the second bubble film layer 16 and the first bubble film layer 14 are firstly bonded on both sides of the base paper layer 15, and the side where the second bubble film layer 16 is located is the inner side 2 of the packaging bag main body 1, and the side where the first bubble film layer 14 is located is the outer side 3 of the packaging bag main body 1. The finished packaging bag main body 1 is in a "U" shape as a whole, and the open end 4 is the sealing end of the packaging bag main body 1. The reinforcing layer 13 is bonded to the outer surface of the first bubble film layer 14, and the outer edge of the reinforcing layer 13 is bonded to the outer waterproof layer 12, and the outer surface of the outer waterproof layer 12 is coated with a hydrophobic agent to form a hydrophobic layer 11, thereby completing the construction of the structural hierarchy in the direction of the outer side 3 of the packaging bag main body 1, and the inner waterproof layer 17 is bonded to the outer surface of the second bubble film layer 16, and the outer surface of the inner waterproof layer 17 is coated with an antistatic agent to form an inner antistatic layer 18, thereby completing the construction of the structural hierarchy in the direction of the inner side 2 of the packaging bag main body 1.

[0023] like Figure 1 and Figure 2 As shown, as one of the preferred embodiments of the utility model, a plurality of evenly distributed first buffer bubbles 141 are provided inside the first bubble film layer 14, and a plurality of evenly distributed second buffer bubbles 161 are provided inside the second bubble film layer 16. The volume of the first buffer bubbles 141 is greater than that of the second buffer bubbles 161, and the distribution density of the second buffer bubbles 161 in the second bubble film layer 16 is greater than the distribution density of the first buffer bubbles 141 in the first bubble film layer 14.

[0024] In the packaging bag body 1, the volume of the first buffer bubble 141 is larger than that of the second buffer bubble 161, and the distribution density of the second buffer bubble 161 in the second bubble film layer 16 is greater than the distribution density of the first buffer bubble 141 in the first bubble film layer 14. The buffer structure of the first bubble film layer 14 and the second bubble film layer 16 cooperates with each other to protect the electronic components and prevent the electronic components from being damaged during transportation or moving. The larger first buffer bubble 141 in the first bubble film layer 14 can provide a larger buffer space, can more effectively absorb external impact force and reduce collision, and can provide protection for the entire packaging bag and electronic components. The smaller and denser second buffer bubbles 161 in the second bubble film layer 16 can disperse the external impact force transmitted from the first bubble film layer 14, thereby further increasing the protection of the electronic components.

[0025] The second buffer bubbles 161 can provide denser buffering. For delicate and easily damaged items such as electronic components, the dense distribution of the second buffer bubbles 161 in the second bubble film layer 16 can better prevent damage caused by external impact, vibration or extrusion. The second buffer bubbles 161 can more effectively disperse and absorb impact force, thereby reducing the risk of damage to electronic components. The first buffer bubbles 141 inside the first bubble film layer 14 can provide an additional protective layer for electronic components. During long-distance transportation or handling, the first bubble film layer 14 can better absorb and disperse impact and vibration from the external environment, thereby further protecting the electronic components. At the same time, the first bubble film layer 14 can also increase the overall strength of the packaging bag body 1 and improve the stability of the packaging bag body 1. During stacking or transportation, it can prevent the packaging bag body 1 from deformation or damage, thereby protecting the safety of internal electronic components.

[0026] The second bubble film layer 16 and the first bubble film layer 14 are made of PPC-PBAT degradable material. The PPC-PBAT degradable material has been disclosed in the patent with publication number CN114292511B. The patent prepares a bubble film for shockproof by mixing 50-70wt% of PPC and 30-50wt% of PBAT. The specific method is: PPC and PBAT raw materials are sucked into a mixer, mixed, plasticized, air-cooled, and pelletized to obtain a degradable modified mixture; the degradable modified mixture is added to a bubble film machine, plasticized, extruded, and cast into a film to obtain a degradable shockproof bubble film. The bubble film prepared by the above method has good degradability and cushioning performance.

[0027] As one of the preferred embodiments of the utility model, the hydrophobic layer 11 is coated on the outer surface of the outer waterproof layer 12, the thickness of the hydrophobic layer 11 is one quarter to one fifth of the outer waterproof layer 12, the thickness of the inner waterproof layer 17 is 0.05mm-0.1mm, and the inner waterproof layer 17 is bonded to the outer surface of the second bubble film layer 16.

[0028] The outer waterproof layer 12 and the inner waterproof layer 17 are both made of degradable polylactic acid materials, which not only ensure the waterproof performance of the packaging bag, but also provide a degradable basis for the entire packaging bag body 1. Polylactic acid is a new type of biodegradable material derived from renewable plant resources such as corn, sweet potatoes, potatoes, etc. It is made of starch raw materials extracted from plants, fermented into lactic acid, and then converted into polylactic acid through a chemical synthesis method. This production process makes polylactic acid naturally degradable, because it is essentially converted from organic matter extracted from plants. Polylactic acid has excellent biodegradability. When it is discarded, it can be completely degraded by microorganisms in the natural environment, and finally generates carbon dioxide and water.

[0029] The hydrophobic layer 11 is a polytetrafluoroethylene hydrophobic layer. Polytetrafluoroethylene has extremely low surface energy, which makes the hydrophobic layer 11 made of it have excellent waterproof performance, thereby reducing the residence time and contact time of water droplets on the surface of the packaging bag body 1. Water droplets can quickly slide down when they contact the surface of the packaging bag body 1, thereby effectively preventing moisture from penetrating into the interior of the packaging bag, so that the electronic components are protected from moisture. The cooperation of the hydrophobic layer 11 composed of polytetrafluoroethylene and the outer waterproof layer 12 forms a double waterproof protection structure. The outer waterproof layer 12 provides basic waterproof function, and the hydrophobic layer 11 further enhances the waterproof effect, so that the waterproof performance of the entire packaging bag body 1 is improved.

[0030] like Figure 3 As shown, as one of the preferred embodiments of the utility model, the reinforcing layer 13 is provided with reinforcing fibers 131 inside, and the reinforcing fibers 131 are in a mesh structure hooked around each other in the reinforcing layer 13 .

[0031] The reinforcing layer 13 is used to increase the structural strength and durability of the packaging bag main body 1. The reinforcing fiber 131 is selected from any one of carbon fiber or fiber reinforced polymer. Both carbon fiber and fiber reinforced polymer have extremely high strength. When the carbon fiber and fiber reinforced polymer are hooked and woven to form a mesh structure and used as the main material of the reinforcing layer 13, the carrying capacity and durability of the packaging bag main body 1 can be improved, thereby extending the service life of the packaging bag. At the same time, the density of carbon fiber and fiber reinforced polymer is relatively low. When the two are used as the main material of the reinforcing layer 13, while giving the packaging bag main body 1 structural strength, it will not significantly increase the overall weight of the packaging bag, thereby increasing the portability of the packaging bag main body 1.

[0032] As one of the preferred embodiments of the present invention, the inner antistatic layer 18 is coated on the outer surface of the inner waterproof layer 17 , and the thickness of the inner antistatic layer 18 is one half to one third of the thickness of the inner waterproof layer 17 .

[0033] The inner antistatic layer 18 is a non-ionic antistatic agent FKD coating. The inner antistatic layer 18 is in direct contact with the electronic components in the packaging bag. The inner antistatic layer 18 is used to make the packaging bag body 1 have an antistatic function. The non-ionic antistatic agent FKD coating can effectively reduce the resistance of the packaging bag surface, reduce the accumulation and discharge of static electricity, and thus protect the electronic components. The chemical properties of the non-ionic antistatic agent FKD are chemical and can maintain its antistatic performance for a long time.

[0034] As one of the preferred embodiments of the utility model, the heat sealing layer 19 is embedded in the opening end 4 of the packaging bag body 1, the left side surface of the heat sealing layer 19 is connected to the base paper layer 15, and the lower surface of the heat sealing layer 19 is respectively connected to the ends of the second bubble film layer 16, the inner waterproof layer 17 and the inner antistatic layer 18.

[0035] The heat sealing layer 19 is an ethylene-vinyl acetate copolymer heat sealing layer. The heat sealing layer 19 is used to seal the packaging bag body 1, so that the packaging bag body 1 has sealing properties, so that the open end 4 of the packaging bag body 1 can be firmly closed, ensuring the safety of electronic components during transportation and storage. Ethylene-vinyl acetate copolymer (EVA) has good thermal viscosity and can melt quickly at appropriate temperature and pressure to form a strong bond with adjacent layers to ensure the sealing of the packaging bag, so that the packaging bag body 1 can be sealed with the heat sealing layer 19 by hot pressing, hot cutting and other methods.

[0036] During heat sealing, the heat sealing layer 19 at the open end 4 is aligned first, and then the heat sealing layer 19 is passed through a heat sealing machine. The heat sealing machine heats the EVA in the heat sealing layer 19 to a melting temperature, at which time the EVA material becomes viscous and has a certain fluidity. Then, the heat sealing machine brings the melted EVA heat sealing layer into close contact with the adjacent layer and maintains it under a certain pressure for a period of time, so that the EVA material forms a uniform thin film on the surface of the adjacent layer. After cooling, the EVA material re-solidifies and forms a firm bond with the adjacent layer, thereby achieving the sealing of the packaging bag.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
