Description

Technical Field

[0001] This utility model relates to the field of packaging film technology, and more specifically, to a high-performance packaging film with strong adhesion. Background Technology

[0002] Packaging film is a thin film material used for packaging and protecting products. It is widely used in food, pharmaceuticals, industrial products, daily necessities, and many other fields. The adhesion of packaging film refers to the bonding strength between the packaging film and the packaged material (such as cartons, bottles, cans, etc.). Good adhesion is an important condition for ensuring packaging quality and protecting products. By rationally selecting materials and optimizing processes, the adhesion of packaging film can be effectively improved, ensuring the airtightness of the packaging and the safety of the product.

[0003] Chinese Patent Publication No. CN220363778U discloses an outer packaging film, including a base layer. The base layer includes several tearable separation films. A dustproof film is connected to the top of each separation film. Adjacent separation films are connected by dividing lines. Both ends of the base layer have open ends, and each open end is connected to a tightening channel. Each tightening channel is connected to a tightening drawstring, and a clamping mechanism is connected to the middle of the tightening drawstring. The base layer is formed by connecting the separation films through dividing lines, resulting in a flat appearance and low cost. By setting tightening channels at the ends of the base layer and connecting them to tightening drawstrings, the tightening and sealing at the ends can be enhanced by pulling the tightening drawstrings during use. The tightening mechanism can be used to tighten the film, which can be adjusted according to the size of the packaged item to enhance the tightening effect. This reduces gaps at the ends, prevents dust from entering, and effectively prevents dust. The packaging structure is also simple.

[0004] However, the above technology has the following drawbacks: when workers use the packaging film, they tear off a portion of it, and the remaining film cannot be collected together, resulting in a loose film that is inconvenient for workers to use next time. Furthermore, the loose film piles up together, taking up a lot of space.

[0005] Therefore, it is necessary to provide a high-performance packaging film with strong adhesion to solve the above problems. Utility Model Content

[0008] The above-described technical solution in this application embodiment has at least the following technical effects: When the staff needs to use the packaging film, the staff first places the base on the flat surface. The staff needs to use the fixing mechanism to make the packaging film no longer fixed. Then the staff pulls the packaging film to take out the required length and tears off the packaging film. Then the staff loosens the fixing structure to fix the packaging film on the mounting frame.

[0009] This application provides a high-performance packaging film with strong adhesion. Through the arrangement of the packaging film body, fixing mechanism, mounting frame, base, and roll, workers can take out only the required amount of packaging film without any loosening of the remaining film.

[0023] When staff use packaging film, they tear off a portion of it, and the remaining film cannot be collected together, resulting in a loose film that is inconvenient for future use. Furthermore, the loose film takes up a lot of space when piled up together.

[0024] Based on this, the problem that packaging films cannot be collected and fixed in related technologies can be improved.

[0025] Please see Figure 1 and Figure 6 A high-performance packaging film with strong adhesion includes a packaging film body 1, a fixing mechanism 2, a mounting frame 7, a base 16, and a roll 17. The roll 17 is mounted on the mounting frame 7, and the base 16 is fixedly connected to the bottom end of the mounting frame 7. The packaging film body 1 is sleeved on the roll 17. The fixing mechanism 2 is mounted on the mounting frame 7, and the mounting frame 7 has a third sliding groove 5 and a pressing groove 6. The fixing mechanism 2 is used to fix the packaging film when it is torn off. The base 16 is used to hold the packaging film.

[0026] Please see Figure 4 and Figure 5The fixing mechanism 2 includes a fixing plate 21, a fixing component 22, and a pressing plate 23. The fixing plate 21 is slidably connected to the mounting frame 7, and the pressing plate 23 is fixedly connected to the mounting frame 7 and located below the fixing plate 21. The fixing component 22 is disposed on the mounting frame 7 and is used to fix the packaging film. The fixing component 22 includes a pressing block 221, a first spring 222, a connecting post 223, a guide post 224, a rotating rod 225, a pressing block 226, and a second spring 227. The pressing block 221 is slidably connected to the mounting frame 7 through the pressing groove 6, and the pressing block 226 is fixedly connected to the top of the pressing block 221. The first spring 222... One end of the first spring 222 abuts against the mounting bracket 7, and the other end of the first spring 222 abuts against the clamping block 221. The guide post 224 is fixedly connected to the bottom end of the clamping block 221 and is slidably connected to the mounting bracket 7 through the third sliding groove 5. The clamping block 221 is provided with a second sliding groove 4, and the fixing plate 21 is provided with a first sliding groove 3. The connecting post 223 is fixedly connected to the mounting bracket 7, and the rotating rod 225 is rotatably connected to the connecting post 223. The two ends of the rotating rod 225 abut against the first sliding groove 3 and the second sliding groove 4, respectively. One end of the second spring 227 abuts against the pressing block 226, and the other end of the second spring 227 abuts against the fixing plate 21.

[0027] With this setup, when staff need to use the packaging film, specifically the main body 1, because the main body 1 is fixed to the pressing plate 23 by the fixing plate 21, the staff first presses the pressing block 226. The pressing block 226 causes the pressing block 221 to slide on the pressing groove 6. Simultaneously, the pressing block 226 compresses the second spring 227. As the pressing block 221 moves, one end of the rotating rod 225 located in the second sliding groove 4 moves downward with the pressing block 221, causing the rotating rod 225 to rotate on the connecting column 223. The other end of the rotating rod 225 moves away from the packaging. The packaging film body 1 moves in a certain direction. As the rotating rod 225 moves upward at one end of the first slide groove 3, it drives the fixing plate 21 away from the packaging film body 1. The guide post 224 slides in the third slide groove 5, ensuring that the pressing block 221 does not deviate during sliding and fixing the sliding trajectory of the pressing block 221. Then, the worker pulls one end of the packaging film body 1, causing the packaging film body 1 to rotate on the roll 17. After the worker pulls it to a certain length, the tear hole 15 is exposed. The worker then tears the packaging film. Finally, the worker releases the pressing block 221. Pressing block 226, under the force of the second spring 227, moves away from the packaging film body 1, causing one end of the rotating rod 225 located in the second slide groove 4 to move away from the packaging film body 1. Simultaneously, it causes the other end of the rotating rod 225 located in the first slide groove 3 to move towards the packaging film body 1. Finally, the bottom surface of the fixing plate 21 abuts against the packaging film body 1, fixing the packaging film body 1 onto the pressing plate 23 and clamping the packaging film. This allows the operator to remove only the required amount of packaging film without the remaining film becoming loose. Users can cut the packaging film to the required length according to specific needs, avoiding overuse or waste. Especially when material costs are a concern, using the film as needed improves work efficiency, avoids repeated measurements and cutting, and makes it easier to store and manage. It takes up little space, can adapt to different workspaces, reduces the need for storage space, and is portable and easy to operate. Especially in situations where frequent access is required, users can easily pull out the required length. Users can adjust the length and width of the film used at any time according to actual conditions, providing better flexibility and adaptability, and eliminating the need for unused materials to accumulate in the stacking area.

[0028] Please see Figure 3 and Figure 6The packaging film body 1 includes an outer layer 8, a reinforcing layer 9, a waterproof layer 10, an adhesive layer 11, a functional coating 12, and a dotted coating 13. The waterproof layer 10 is fixedly connected to the outer layer 8, the functional coating 12 is fixedly connected to the waterproof layer 10, the reinforcing layer 9 is fixedly connected to the functional coating 12, the adhesive layer 11 is fixedly connected to the reinforcing layer 9, and the dotted coating 13 is fixedly connected to the adhesive layer 11. The packaging film body 1 has multiple tear holes 15. The dotted coating 13 has grooves 14 on the side away from the adhesive layer 11, and the grooves 14 are evenly distributed on the dotted coating 13.

[0029] With this setup, when using the packaging film, staff can tear it off the roll 17 by hand along the tear hole 15. The easy-tear line makes it easier and less strenuous for users to tear the packaging film, ensuring that the main body 1 of the packaging film will not be damaged during the tearing process. The outer layer 8 is set as a wear-resistant layer to increase the overall strength of the packaging film. The waterproof layer 10 is made of polyethylene material, which can effectively isolate moisture and protect the internal products from moisture. The functional coating 12 is made of polyacrylate coating to enhance the performance of the film, such as waterproof, oil-proof, antibacterial or antistatic. The reinforcing layer 9 is made of glass fiber to improve the overall mechanical strength and adhesion performance. The adhesive layer 11 is made of low-density polyethylene (LDPE) to improve the adhesion between the packaging material and the contents. The concave coating 13 is provided with grooves 14, designed with texture or uneven structure to increase the surface roughness, which can provide more bonding points and improve adhesion.

[0030] Working principle: When the staff needs to use the packaging film, specifically the main body 1, the main body 1 is fixed to the pressing plate 23 by the fixing plate 21. First, the staff presses the pressing block 226, which causes the pressing block 221 to slide on the pressing groove 6. Simultaneously, the pressing block 226 compresses the second spring 227. As the pressing block 221 moves, one end of the rotating rod 225 located in the second slide groove 4 moves downwards, causing the rotating rod 225 to rotate on the connecting column 223. The other end of the rotating rod 225 moves away from the main body 1. As the end of the rotating rod 225 in the first slide groove 3 moves upwards, it causes the fixing plate 21 to move away from the main body 1. The guide column 224 slides in the third slide groove 5, thus ensuring pressure. When block 221 slides, it will not deviate. The sliding trajectory of the fixed pressing block 221 is fixed. Then, the worker pulls one end of the packaging film body 1, so that the packaging film body 1 rotates on the roll 17. After the worker pulls it to a certain length, the tear hole 15 is exposed. The worker uses his hand to tear the packaging film off the roll 17 along the tear hole 15. Then, the worker releases the pressing block 226. Under the action of the second spring 227, the pressing block 226 moves away from the packaging film body 1, which drives one end of the rotating rod 225 located in the second slide groove 4 to move away from the packaging film body 1. At the same time, it drives the other end of the rotating rod 225 located in the first slide groove 3 to move towards the packaging film body 1. Finally, the bottom surface of the fixing plate 21 abuts against the packaging film body 1, fixing the packaging film body 1 on the pressing plate 23.
