Description

Technical Field

[0001] The present application relates to the technical field of packaging material technology, and in particular to a moisture-proof multifunctional bubble film packaging bag. Background Art

[0002] A packaging bag is a flexible container made of plastic, paper or composite materials, mainly used to hold, protect and transport various items. Its core functions include physical protection such as shockproof, moisture-proof, damage-proof, sealed preservation, blocking air, moisture and light, and information identification through printing to display product descriptions and barcodes. According to structure and purpose, it can be divided into flat bags, self-supporting bags, zipper bags, food packaging bags, industrial packaging bags emphasizing strength and environmentally friendly bags using degradable materials. Modern packaging bags often use multi-layer composite technology such as PET / AL / PE structure and combine functional design such as modified atmosphere preservation and anti-static. They must meet technical indicators such as mechanical properties and barrier properties. As a key link in the supply chain in the logistics and retail fields, its development trend is evolving towards intelligent integrated RFID tags, green use of degradable materials such as PLA / PBAT, and customized application of variable printing technology.

[0003] The sealing performance of conventional packaging bags is insufficient, and they are usually sealed by simple heat sealing or gluing, which makes it difficult to form a completely enclosed structure. As a result, the internal items are easily affected by moisture and deteriorate in humid environments or during long-term storage. The existing packaging bags lack an effective top sealing design, and cannot be opened and sealed repeatedly after sealing, and are less convenient to use. Ordinary bubble films are mostly single-layer or simple multi-layer structures, which can neither effectively block the damage of ultraviolet rays to the contents nor have antibacterial functions, and are difficult to meet the packaging needs of products with high hygiene requirements such as food and medicine. The buffering protective layer structure of traditional packaging bags is single and has limited impact resistance. During transportation, the bubbles are easily broken due to squeezing and the protective effect is lost. Packaging bags on the market often ignore anti-static design, which poses a safety hazard when packaging electronic products. These functional defects seriously limit the application of bubble film packaging bags in precision instruments, medical supplies, high-end foods and other fields. There is an urgent need for a new packaging bag solution that integrates multiple functions such as moisture-proof, UV protection, antibacterial, and impact resistance. Summary of the Invention

[0006] As a preferred solution of the present application, the first bubble film and the second bubble film are composed of an anti-wear layer, an ultraviolet blocking layer, a bubble buffer layer, an adhesive transition layer, a high barrier layer, and a food contact layer. The anti-wear layer is a biaxially oriented polyamide film, the ultraviolet blocking layer is an antimony-doped tin oxide composite film, and the bubble buffer layer is a modified low-density polyethylene bubble column array material; the adhesive transition layer is an ethylene-ethyl acrylate copolymer hot melt adhesive film, the high barrier layer is an aluminum foil polyvinyl alcohol composite film, and the food contact layer is a cast polypropylene antibacterial film.

[0007] As a preferred solution of the present application, the edge sealing layer and the inner wall are provided with a sealant, the sealant is tightly connected to the outer wall of the first bubble film and the second bubble film, and the sealant is a modified polyolefin hot melt adhesive. As a preferred solution of this application, the front end outer surface of the second sealing strip is provided with a rectangular mounting groove adapted to the fixing strip, and the second sealing strip is fixedly connected to the fixing strip through the rectangular mounting groove. As a preferred solution of the present application, the outer surface of the rear end of the first sealing strip is provided with a circular mounting groove adapted to the needle fixing block, and the first sealing strip is fixedly connected to the needle fixing block through the circular mounting groove.

[0008] In summary, this application includes at least one of the following beneficial technical effects: The moisture-proof multifunctional bubble film packaging bag of the present application effectively solves many shortcomings of traditional packaging bags in moisture resistance and sealing through innovative multi-layer composite structure and sealing system design. The design of the six-layer functional composite film structure enables the packaging bag to have both excellent physical protection performance and functional characteristics. The setting of the anti-wear layer greatly improves the durability of the packaging bag and avoids the problem of damage caused by friction during transportation; the addition of the UV blocking layer effectively blocks the damage to the contents caused by harmful rays in the sun, and is particularly suitable for packaging light-sensitive items; the combination of the high barrier layer and the food contact layer not only significantly improves the moisture-proof performance, but also ensures food contact safety.

This overall sealing solution not only solves the problem that traditional packaging bags are easily affected by moisture in humid environments, but also avoids dependence on electricity through mechanical sealing design, so that the packaging bag can maintain stable sealing performance under various environmental conditions. In addition, the precise coordination design between the components not only ensures the sealing effect, but also takes into account the convenience of opening and resealing, making the packaging bag particularly suitable for packaging items that need to be taken multiple times, and has broad application prospects in daily consumer goods, medical supplies and other fields.

[0012] The following is combined with Figure 1-4 This application is described in further detail.

[0013] See also Figure 1 , a moisture-proof multifunctional bubble film packaging bag, comprising a first bubble film 1 and a second bubble film 102 arranged opposite to each other, characterized in that: the three edges of the first bubble film 1 and the second bubble film 102 are sealed and connected with an edge sealing layer 101, the upper outer surfaces of the first bubble film 1 and the second bubble film 102 are provided with a top sealing structure 2, the front inner surface of the top sealing structure 2 is fixedly connected with a fixing strip 201, the top sealing structure 2 includes a second sealing strip 206 and a first sealing strip 202, the rear end outer surface of the fixing strip 201 is fixedly connected with a liquid glue bag 205, the rear end outer surface of the liquid glue bag 205 is detachably connected with an anti-puncture layer 207, the front end outer surface of the first sealing strip 202 is fixedly connected It is connected to a puncture needle fixing block 204, and the front end outer surface of the puncture needle fixing block 204 is fixedly connected to the puncture needle 203. The first bubble film 1 and the second bubble film 102 are composed of an anti-wear layer 104, an ultraviolet blocking layer 105, a bubble buffer layer 106, an adhesive transition layer 107, a high barrier layer 108, and a food contact layer 109. The anti-wear layer 104 is a biaxially oriented polyamide film, the ultraviolet blocking layer 105 is an antimony-doped tin oxide composite film, and the bubble buffer layer 106 is a modified low-density polyethylene bubble column array material; the adhesive transition layer 107 is an ethylene-ethyl acrylate copolymer hot melt adhesive film, the high barrier layer 108 is an aluminum foil polyvinyl alcohol composite film, and the food contact layer 109 is a cast polypropylene antibacterial film.

[0014] The sealing system of the packaging bag forms a basic closed space through the three-side edge sealing layer 101 of the first bubble film 1 and the second bubble film 102, and the top sealing structure 2 realizes the sealing function of repeated opening and closing. When the packaging bag needs to be sealed, the user tears off the anti-puncture layer 207 and presses the top sealing structure 2 to make the puncture needle 203 on the first sealing strip 202 puncture the liquid glue bag 205. The glue pre-stored inside then flows out and is evenly distributed on the contact surface between the first sealing strip 202 and the second sealing strip 206. The anti-puncture layer 207 plays a protective role in this process to prevent the plastic bag from being accidentally punctured when not in use. The fixing strip 201 is The entire sealing system provides structural support to ensure the alignment accuracy during sealing. After the sealing is completed, the first sealing strip 202 and the second sealing strip 206 are bonded by glue to form a firm seal. This mechanically triggered sealing method avoids the limitation of traditional heat sealing requiring special equipment. When it needs to be opened again, only appropriate external force is needed to separate the sealing strips. The characteristics of the glue allow repeated bonding multiple times without affecting the sealing effect. The edge sealing layer 101 uses a specially formulated sealant 103 that can adapt to different environmental temperature changes and always maintain the sealing integrity of the edge, forming a double moisture-proof barrier together with the top sealing structure 2.

[0015] The six-layer composite structure of the first and second bubble films 102 works synergistically to provide multifunctional protection. The outermost anti-wear layer 104 is made of a high-strength film material to effectively resist surface wear during transportation. The UV barrier layer 105 uses a special material ratio to selectively filter harmful UV rays while maintaining sufficient visible light transmittance to facilitate observation of the contents. The modified bubble structure of the bubble cushion layer 106 absorbs kinetic energy through air cushioning during impact, and its unique arrangement improves overall compressive resistance. The adhesive transition layer 107 not only ensures a firm bond between the layers but also buffers the stress generated by temperature changes in each layer. The dense structure of the high-barrier layer 108 forms a molecular barrier, effectively blocking the penetration of water vapor and oxygen. The innermost food contact layer 109 uses an antibacterial formula to inhibit microbial growth, ensuring the hygienic safety of items in direct contact. The performance of each functional layer is optimized through precise thickness control and interface treatment, allowing the composite film to maintain flexibility while also providing multiple protective functions. The working principle of this composite structure lies in the functional complementarity and synergistic effect of the materials in each layer, providing more comprehensive protection than traditional single-layer bubble film.

[0016] The edge sealing layer 101 and the inner wall are provided with a sealant 103, and the sealant 103 is tightly connected to the outer wall of the first bubble film 1 and the second bubble film 102. The sealant 103 is a modified polyolefin hot melt adhesive. The front end outer surface of the second sealing strip 206 is provided with a rectangular mounting groove adapted to the fixing strip 201. The second sealing strip 206 is fixedly connected to the fixing strip 201 through the rectangular mounting groove. The rear end outer surface of the first sealing strip 202 is provided with a circular mounting groove adapted to the needle fixing block 204. The first sealing strip 202 is fixed to the needle fixing block 204 through the circular mounting groove. The front end outer surface of the anti-puncture layer 207 is bonded with double-sided tape, and the front end outer surface of the double-sided tape is bonded to the rear end outer surface of the liquid rubber bag 205. The front end outer surface of the puncture needle 203 is in contact with the rear end outer surface of the anti-puncture layer 207. The liquid rubber bag 205 is made of polyethylene material. The liquid rubber bag 205 is a sealing bag, and 502 glue is provided in the inner cavity of the sealing bag. The lower end outer surface of the second sealing strip 206 is connected to the upper end outer surface of the first bubble film 1, and the lower end outer surface of the first sealing strip 202 is connected to the upper end outer surface of the second bubble film 102.

[0017] In terms of structural design, the packaging bag has constructed a three-dimensional sealing protection system. The edge sealing layer 101 and the top sealing structure 2 form a three-dimensional sealing network. The edge seal uses modified polyolefin hot melt adhesive 103 to achieve permanent sealing, while the top seal is repeatedly opened and closed through a mechanical trigger structure. This double sealing mechanism breaks through the limitations of the single sealing mode of traditional packaging, which not only ensures the basic sealing reliability, but also meets the convenience requirements in actual use. The various components of the sealing structure are functionally linked through precise coordination, such as the second sealing strip 206 and the rectangular groove of the fixing strip 201, and the first sealing strip 202 and the circular groove of the needle fixing block 204. These specific shapes of joint designs ensure accurate positioning and firm connection between components. The anti-puncture layer 207 and the liquid glue bag 205 are detachably connected by double-sided tape, which not only ensures transportation safety but also does not affect the functional realization during use, reflecting the humanized considerations of the design.

[0018] From the perspective of functional implementation, this solution creatively combines physical protection with chemical protection. The 502 glue encapsulated in the liquid glue bag 205 serves as a chemical sealing medium, and synergizes with the physical sealing structure composed of the first sealing strip 202 and the second sealing strip 206 to form a composite sealing effect. When the puncture needle 203 pierces the plastic bag, the outflowing glue not only fills the microscopic gaps between the sealing strips, but also penetrates into the micropores on the surface of the material, achieving a sealing effect at the molecular level. This physical-chemical synergistic sealing principle enables the packaging bag to adapt to the sealing requirements of different environmental conditions, especially in situations where the temperature and humidity fluctuate greatly, it can still maintain stable sealing performance. The material selection of each functional layer also reflects the concept of multifunctional integration. For example, the liquid glue bag 205 made of polyethylene material ensures both flexibility and good chemical stability, ensuring that the glue will not deteriorate during long-term storage.

[0019] At the practical application level, this design scheme fully considers the feasibility of industrial production and the diversity of usage scenarios. All sealing components adopt a standardized and modular design to facilitate large-scale production and assembly. For example, the connection between the second sealing strip 206 and the first bubble film 1, and the connection between the first sealing strip 202 and the second bubble film 102 are both directly fixed, which simplifies the production process. The detachable design of the anti-puncture layer 207 not only reduces the transportation loss rate, but also facilitates the use of end users. The overall structural design takes into account the flexibility and rigidity requirements of the packaging bag. While ensuring the sealing reliability, it does not affect the folding, storage and transportation stacking performance of the packaging bag. This balanced design enables the product to adapt to the needs of different application scenarios from food packaging to precision instrument protection.

[0020] The systematic innovation of this technical solution is also reflected in fault prevention and long-term maintenance. The provision of the anti-puncture layer 207 effectively avoids the risk of accidental puncture of the plastic bag during transportation. This preventive design greatly improves the reliability of the product. The modified polyolefin properties of the sealant 103 give it self-healing capabilities. When tiny cracks appear at the edge seal, the characteristics of the material itself can compensate for the defects to a certain extent and extend the service life of the packaging bag. The modular design of the top sealing structure also facilitates the replacement and maintenance of damaged parts, reflecting the concept of sustainable design.

[0021] In terms of market application prospects, the design of this moisture-proof multifunctional bubble film packaging bag meets the current market's urgent demand for high-performance packaging. In the food industry, its moisture-proof and antibacterial properties can extend the shelf life of food; in the field of electronic products, its anti-static and buffering protection functions can effectively protect precision components; in pharmaceutical packaging, its high barrier and hygienic properties meet strict industry standards. This wide range of application adaptability gives the product a broad market space. At the same time, the resealable feature also responds to the market trend of environmental protection and plastic reduction, and is in line with the concept of sustainable development.

[0022] The moisture-proof multifunctional bubble film packaging bag of the present application effectively solves many shortcomings of traditional packaging bags in moisture resistance and sealing through innovative multi-layer composite structure and sealing system design. The design of the six-layer functional composite film structure enables the packaging bag to have both excellent physical protection performance and functional characteristics. The setting of the anti-wear layer greatly improves the durability of the packaging bag and avoids the problem of damage caused by friction during transportation; the addition of the UV blocking layer effectively blocks the damage to the contents caused by harmful rays in the sun, and is particularly suitable for packaging light-sensitive items; the combination of the high barrier layer and the food contact layer not only significantly improves the moisture-proof performance, but also ensures food contact safety. This composite structure design enables the packaging bag to maintain the cushioning performance of traditional bubble film while expanding its application range in special environments, and can meet the storage and transportation needs of products with high packaging requirements such as food, medicine, and precision instruments.

[0023] The innovative design of the top self-sealing system is another highlight of this application. Different from the limitation of one-time sealing of traditional packaging bags, the repeated sealing function of the packaging bag is realized through the clever combination of liquid glue bag and puncture needle, which greatly improves the convenience of use; the setting of the anti-puncture layer not only ensures the reliability of the sealing system, but also avoids the risk of accidental puncture during transportation; the special edge sealing layer uses high-performance hot melt adhesive to ensure a long-lasting sealing effect on the three edges. This overall sealing solution not only solves the problem that traditional packaging bags are easily affected by moisture in humid environments, but also avoids dependence on electricity through mechanical sealing design, so that the packaging bag can maintain stable sealing performance under various environmental conditions. In addition, the precise coordination design between the components not only ensures the sealing effect, but also takes into account the convenience of opening and resealing, making the packaging bag particularly suitable for packaging items that need to be taken multiple times, and has broad application prospects in daily consumer goods, medical supplies and other fields.

[0024] Through systematic structural design and innovative functional integration, it has successfully solved the multiple pain points of traditional bubble film packaging bags in terms of sealing performance, protective function and user experience. Its technical solution not only includes innovative combinations at the material level, but also covers ingenious ideas in structural design, and also takes into account the convenience and reliability of practical applications, forming a complete technical system. This all-round, multi-level innovative design not only improves the product performance of bubble film packaging bags, but also provides new ideas and directions for technological progress in the entire packaging industry. The promotion and implementation of this solution will effectively promote the development of packaging products towards functionalization, intelligence and environmental protection, with significant economic and social benefits.

[0025] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
