Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and in particular to a high-sealing vacuum high-temperature bag. Background Technology

[0002] Vacuum bags, also known as reduced-pressure packaging or aluminum-plastic composite bags, are a type of packaging that removes all the air from the container and seals it, creating a highly depressurized environment. This low-oxygen environment effectively inhibits the growth of microorganisms, thereby extending the shelf life of food or other items and maintaining their freshness. As a highly efficient packaging method, vacuum bags play an important role in food preservation, industrial protection, and special applications due to their unique materials and functions. Choosing the right type of vacuum bag can better meet actual needs and improve packaging effectiveness.

[0003] Existing vacuum high-temperature bags typically use conventional sealing methods, such as sealing strips and zipper sliders. However, sealing strips are prone to aging or deformation after prolonged use, making it difficult to guarantee the sealing performance. Therefore, a vacuum high-temperature bag with high sealing performance is needed. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a high-sealing vacuum high-temperature bag. This solves the problem that existing vacuum high-temperature bags usually use conventional sealing methods, such as sealing strips and zipper sliders, which are prone to aging or deformation of the sealing strips after long-term use, making it difficult to guarantee the sealing performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing-performance vacuum high-temperature bag, comprising a vacuum bag and a vacuum bag sealing assembly. The vacuum bag sealing assembly includes a sealing strip A, a sealing strip B, strip-shaped sealing ridges, rectangular sealing blocks, strip-shaped sealing grooves, and rectangular sealing grooves. Sealing strip A is fixedly connected to the surface of the vacuum bag, and sealing strip B is fixedly connected to the surface of the vacuum bag. Sealing strip A and sealing strip B are in contact.

The number of rectangular sealing grooves is the same as the number of rectangular sealing blocks, and they are all opened on the surface of sealing strip B. The strip-shaped sealing ridges and strip-shaped sealing grooves are engaged, and the rectangular sealing blocks and rectangular sealing grooves are engaged.

[0026] Please see Figure 1-5This utility model provides a technical solution: a high-sealing vacuum high-temperature bag, including a vacuum bag 1 and a vacuum bag sealing assembly. The vacuum bag sealing assembly includes a sealing strip A9, a sealing strip B10, strip-shaped sealing ridges 12, rectangular sealing blocks 13, strip-shaped sealing grooves 14 and rectangular sealing grooves 15. The sealing strip A9 is fixedly connected to the surface of the vacuum bag 1, and the sealing strip B10 is fixedly connected to the surface of the vacuum bag 1. The sealing strips A9 and B10 are in contact. There are two strip-shaped sealing ridges 12, both of which are fixedly connected to the surface of the sealing strip A9. There are multiple rectangular sealing blocks 13, which are equidistantly fixedly connected to the surface of the sealing strip A9 in a linear array. The rectangular sealing blocks 13 are located between two strip-shaped sealing ridges 12. The number of strip-shaped sealing grooves 14 is the same as that of the strip-shaped sealing ridges 12, and they are all opened on the surface of the sealing strip B10. The number of rectangular sealing grooves 15 is the same as that of the rectangular sealing blocks 13, and they are all opened on the surface of the sealing strip B10. The strip-shaped sealing ridges 12 and strip-shaped sealing grooves 14 are engaged, and the rectangular sealing blocks 13 and rectangular sealing grooves 15 are engaged.

[0027] Furthermore, a sealing edge B4 is fixedly connected to the surface of sealing strip A9, a sealing edge A3 is fixedly connected to the surface of sealing strip B10, sealing edge A3 is in contact with sealing edge B4, a sealing strip B8 is fixedly connected to the surface of sealing edge B4, a sealing strip A7 is fixedly connected to the surface of sealing edge A3, and sealing strip A7 is snapped into the sealing strip B8. Sealing strip A7 is fixedly connected to the top of both sealing edge A3 and sealing edge B4. A handle 5 is fixedly connected to the surface of both sealing edge A3 and sealing edge B4. An air extraction nozzle 2 is fixedly connected to the surface of vacuum bag 1. An opening 6 is opened on the surface of handle 5. A PET surface layer 16 is fixedly connected to the inside of vacuum bag 1. A nylon layer 17 is fixedly connected to the inside of vacuum bag 1. A polyethylene layer 18 is fixedly connected to the inside of vacuum bag 1. The nylon layer 17 is located between the PET surface layer 16 and the polyethylene layer 18. The nylon layer 17 is fixedly connected to both the PET surface layer 16 and the polyethylene layer 18. An accommodating cavity 11 is opened inside vacuum bag 1.

[0028] Furthermore, during use, the vacuum bag first achieves an internal seal between sealing strip A9 and sealing strip B10. The strip-shaped sealing ridge 12 and rectangular sealing block 13 on sealing strip A9 respectively engage with the strip-shaped sealing groove 14 and rectangular sealing groove 15 on sealing strip B10, ensuring the sealing performance and stability between sealing strip A9 and sealing strip B10. Subsequently, sealing strip B8 is inserted into the interior of sealing strip A7, achieving a seal between sealing edge A3 and sealing edge B4. The seal between sealing edge A3 and sealing edge B4 provides further protection between sealing strip A9 and sealing strip B10, further ensuring the sealing effect. The separating edge 19 on sealing edge A3 and sealing edge B4 can be used to separate sealing edge A3 from the sealing strip. Edge B4 makes it easier to open sealing edges A3 and B4. Handle 5, together with opening 6, facilitates the extraction of the vacuum bag. PET surface layer 16 is made of polyethylene terephthalate. As a surface material, it has good optical properties and printability, and high transparency, allowing consumers to clearly see the product inside the packaging. Nylon layer 17 is made of nylon. As an intermediate layer, it has strong tensile strength and abrasion resistance, which can improve the puncture and tear resistance of the vacuum bag and effectively protect the product inside the packaging from external physical damage. Polyethylene layer 18 is made of polyethylene. As the innermost layer, it has good heat-sealing performance and chemical resistance, and can form a good heat-sealing bond with the heat sealing head of the packaging machine to ensure the airtightness of the vacuum bag.

[0029] Furthermore, this vacuum bag significantly improves its overall performance through a multi-layer sealing structure design. First, it achieves a basic seal by using a snap-fit ​​seal between sealing strip A9 and sealing strip B10 (with the strip sealing ridge 12 and rectangular sealing block 13 embedded in the strip sealing groove 14 and rectangular sealing groove 15). Combined with the engagement of sealing strip B8 and sealing strip A7, a second sealing condition is formed to ensure overall sealing performance. This solves the problem that existing vacuum high-temperature bags typically use conventional sealing methods, such as sealing strips and zipper sliders, which are prone to aging or deformation of the sealing strips after long-term use, making it difficult to guarantee sealing performance.
