Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a printed antistatic aluminum foil bag. Background Technology

[0002] In modern industrial production and daily life, packaging technology plays a crucial role in the storage, transportation, and protection of goods, especially for static-sensitive items such as electronic components and precision instruments. Ordinary packaging materials cannot meet their protective needs. Although traditional aluminum foil bags have a certain barrier performance, they have many shortcomings: First, their anti-static performance is poor. During production, transportation, and storage, static electricity can easily accumulate due to friction and other factors, and electrostatic discharge may damage static-sensitive items. Second, the sealing structure has poor sealing effect, making it difficult to effectively prevent the intrusion of moisture and oxygen, leading to moisture absorption, oxidation, and deterioration of the items inside the bag. Therefore, we have launched a printed anti-static aluminum foil bag. Utility Model Content

[0003] The main objective of this invention is to provide a printed antistatic aluminum foil bag that can effectively solve the problems in the background art.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A printed antistatic aluminum foil bag includes a printed outer layer 1, a groove 3 at the upper front end of the printed outer layer 1, tear-off notches 6 at the upper left and right sides of the printed outer layer 1, an adhesive inner layer 2 fixedly connected to the inner wall of the printed outer layer 1, a reflective marking layer 5 at the middle front end of the printed outer layer 1, and an upper sealing strip 4 and a lower sealing strip 7 respectively provided on the upper part of the inner wall of the printed outer layer 1.

[0027] The tear notch 6 is symmetrically positioned along the center line of the outer printed layer 1 of the bag.

[0028] In this embodiment, the inner adhesive layer 2 of the bag body includes a shielding layer 21, a buffer layer 22 is fixedly connected to the rear wall of the shielding layer 21, an antistatic layer 23 is fixedly connected to the rear wall of the buffer layer 22, and the shielding layer 21 is fixedly connected to the inner wall of the printed outer layer 1 of the bag body. The areas of the buffer layer 22 and the antistatic layer 23 are the same as the area of ​​the inner adhesive layer 2 of the bag body, and the edges of the three are aligned.

[0029] Through the above scheme: the inner adhesive layer 2 of the bag body is composed of a shielding layer 21, a buffer layer 22, and an antistatic layer 23. The shielding layer 21 is usually made of aluminum foil, which has excellent barrier properties and conductivity, and can effectively block external electromagnetic interference and shield static electricity, preventing the items inside the bag from being affected by external static electricity. The buffer layer 22 is made of EPE pearl cotton, which can absorb the impact force when the aluminum foil bag is squeezed or bumped by the outside, reducing the damage to the items inside the bag. The antistatic layer 23 is made of polyethylene material with added antistatic agent, which can conduct away the static electricity generated inside the bag in time and avoid static electricity accumulation. The three are tightly connected, and the area of ​​the buffer layer 22 and the antistatic layer 23 is the same as the area of ​​the inner adhesive layer 2 of the bag body and the edges are aligned, forming a complete protective system that comprehensively protects the safety and stability of the items inside the bag, effectively extending the shelf life of the items. It is suitable for packaging items such as electronic components and precision instruments that are sensitive to static electricity.

[0030] In this embodiment, the upper sealing strip 4 includes a first heat-sealing layer 41, and the inner wall of the first heat-sealing layer 41 is provided with a cross strip 42. The first heat-sealing layer 41 is fixedly connected to the upper part of the inner bag wall of the printed outer layer 1 of the bag body. The lower sealing strip 7 includes a second heat-sealing layer 71, and the inner wall of the second heat-sealing layer 71 is provided with an interlocking strip 72. The interlocking strip 72 is fixedly connected to the upper part of the inner bag wall of the printed outer layer 1 of the bag body. The first heat-sealing layer 41 is located directly above the second heat-sealing layer 71. The intersection nodes of the cross strip 42 are evenly distributed, and the distance between the edge of the cross strip 42 and the edge of the first heat-sealing layer 41 is 2mm.

[0031] Through the above scheme: the first heat-sealing layer 41 of the upper sealing strip 4 is usually made of polyethylene material with good thermoplasticity, and the second heat-sealing layer 71 of the lower sealing strip 7 is also made of a material with good thermoplasticity. Under the action of heating and pressure, the first heat-sealing layer 41 and the second heat-sealing layer 71 can be firmly sealed together, and the first heat-sealing layer 41 is located directly above the second heat-sealing layer 71, ensuring the regularity of the seal. The cross strips 42 of the inner wall of the first heat-sealing layer 41 are made of plastic material with good toughness, the cross nodes are evenly distributed, and the edges of the cross strips 42 are aligned with the edges of the first heat-sealing layer 41. With a spacing of 2mm, the interlocking strip 72 on the inner wall of the lower sealing strip 7 is made of a plastic material with a certain degree of elasticity and a raised height of 1mm. The cross strip 42 and the interlocking strip 72 work together. When the aluminum foil bag is sealed, the cross strip 42 and the interlocking strip 72 can effectively increase the friction and contact area at the sealing point, making the seal tighter and improving the sealing performance of the aluminum foil bag. This prevents external moisture, oxygen, etc. from entering the bag, better protecting the contents of the bag. At the same time, it enhances the firmness of the seal, avoids the seal from cracking during use, and extends the service life of the aluminum foil bag.

[0032] It should be noted that this utility model is a printed antistatic aluminum foil bag. During use, the groove 3 at the front end of the printed outer layer 1 of the bag body and the symmetrically arranged tear notches 6 make it easy for users to tear the bag open. The reflective marking layer 5 in the middle of the front end is used to quickly identify the items inside the bag. The shielding layer 21 of the inner layer 2 of the bag body isolates external electromagnetic interference and static electricity. The buffer layer 22 and the antistatic layer 23 have the same area as the inner layer 2 of the bag body and are aligned at the edges, respectively buffering external force and dissipating internal static electricity. The first heat-sealing layer 41 of the upper sealing strip 4 and the second heat-sealing layer 71 of the lower sealing strip 7 correspond to each other and are sealed by heating and pressurizing. The cross strips 42 evenly distributed on the inner wall of the first heat-sealing layer 41 and the interlocking strips 72 with a height of 1mm on the inner wall of the second heat-sealing layer 71 further improve the sealing performance and firmness, thereby ensuring the safe storage and convenient use of the items inside the bag in all aspects.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
