Description

Technical Field

[0001] This utility model relates to the field of stretch film technology, and in particular to a high-strength stretch film. Background Technology

[0002] Stretch film is a highly tensile plastic film made primarily of linear low-density polyethylene (LLDPE). It is mainly used to secure loose items (such as cartons and palletized goods) into a whole, while also providing dust and moisture protection. It is a commonly used basic material in logistics, warehousing, and industrial packaging. Stretch film is mainly used in logistics packaging to fix and protect various items, providing dust and moisture protection. Stretch film comes in a variety of colors, including transparent, colored, blue, black, and yellow, to meet different needs. However, existing stretch films have certain drawbacks in their use. In logistics packaging scenarios, existing stretch films have significant performance shortcomings: First, the film surface is easily scratched by sharp objects such as cargo edges and pallet protrusions, resulting in structural damage and directly weakening the overall strength during packaging. Consequently, when subjected to external forces such as bumps and vibrations during subsequent transportation, it is prone to breakage and cannot continuously and stably secure the goods. Second, its resistance to compression is weak, making it difficult to provide effective protection against the vertical pressure of stacked goods or collisions and compressions during transportation. To ensure the safety of goods transportation, companies often need to compensate for these performance deficiencies by wrapping the film in multiple layers. This not only increases the packaging operation process but also leads to a significant increase in the consumption of stretch film materials, resulting in significant resource waste. Therefore, we propose a high-strength wrapping film. Utility Model Content

[0003] In view of the technical problems in the prior art, the surface of the film is easily scratched by sharp objects such as the edges of goods and the protrusions of the pallet, which damages its own structure and directly weakens the overall strength during the packaging process. As a result, it is very easy to break when subjected to external forces such as bumps and vibrations during subsequent transportation, and it cannot continuously and stably fix the goods. It also has weak resistance to compression and is difficult to form effective protection against the vertical pressure of stacked goods or collisions and compressions during transportation. This utility model provides a high-strength stretch film.

[0004] The technical solution adopted by this utility model is: a high-strength wrapping film, comprising an LLDPE first base layer and an LDPE second base layer, wherein a reinforcing layer group and a pressure-resistant layer group are disposed between the LLDPE first base layer and the LDPE second base layer, the reinforcing layer group being located below the pressure-resistant layer group, the reinforcing layer group comprising a reinforcing composite layer, a fiber adhesive strip, an internal adhesive core, and a connecting film, wherein the fiber adhesive strip is disposed in the middle of the reinforcing composite layer, the internal adhesive core is disposed in the middle of the fiber adhesive strip, the connecting film is disposed between the internal adhesive core and the fiber adhesive strip, and a pressure-resistant cavity is disposed in the middle of the pressure-resistant layer group.

[0005] Furthermore, an anti-corrosion composite layer is fixedly connected to the upper outer surface of the LDPE second base layer, and a superhydrophobic coating is provided on one end of the outer surface of the anti-corrosion composite layer.

[0006] Furthermore, the fiber strips are arranged in an interlaced mesh structure.

[0007] Furthermore, the built-in adhesive core and the connecting film are integrally formed, and the built-in adhesive core is fixedly connected to the fiber adhesive strip through the connecting film.

[0008] Furthermore, the pressure-resistant layer assembly and the pressure-resistant cavity are integrally formed, and the width of the pressure-resistant cavity is .mm.

[0009] Furthermore, the anti-corrosion composite layer and the superhydrophobic coating are integrally formed.

[0010] The beneficial effects of this utility model are: In this invention, the reinforcing layer enhances the overall scratch and cut resistance of the stretch film through the fiber strips within the reinforcing composite layer. This improves the reliability of the stretch film during logistics packaging, prevents scratches from sharp objects during packaging, avoids structural damage, ensures overall strength during packaging, and prevents breakage during transportation. The pressure-resistant layer effectively enhances the pressure resistance of the stretch film through the pressure-resistant cavity, improving its packaging protection and reducing material usage to avoid waste. The anti-corrosion composite layer and superhydrophobic coating provide anti-fouling and corrosion resistance to the outer layer of the stretch film, preventing dirt from adhering to its surface and improving the protective effect of the stretch film packaging.

[0015] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0016] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a high-strength wrapping film.

[0017] The specific technical solution includes an LLDPE first base layer 1 and an LLDPE second base layer 4. A reinforcing layer group 2 and a compressive strength layer group 3 are disposed between the LLDPE first base layer 1 and the LLDPE second base layer 4. The reinforcing layer group 2 is located below the compressive strength layer group 3. The reinforcing layer group 2 includes a reinforcing composite layer 201, a fiber adhesive strip 202, an internal adhesive core 203, and a connecting film 204. The fiber adhesive strip 202 is disposed in the middle of the reinforcing composite layer 201, the internal adhesive core 203 is disposed in the middle of the fiber adhesive strip 202, and the connecting film 204 is disposed between the internal adhesive core 203 and the fiber adhesive strip 202. Between the adhesive strips 202, a pressure-resistant cavity 7 is provided in the middle of the pressure-resistant layer group 3. An anti-corrosion composite layer 5 is fixedly connected to the upper outer surface of the LDPE second base layer 4. A superhydrophobic coating 6 is provided on the outer surface of one end of the anti-corrosion composite layer 5. When in use, the reinforcing layer group 2 can improve the overall scratch and cut resistance of the stretch film through the fiber adhesive strips 202 in the reinforcing composite layer 201. This can improve the reliability of the stretch film in logistics packaging, prevent it from being scratched by sharp objects during packaging, avoid damage to its own structure, ensure the overall strength during packaging, and prevent breakage during transportation.

[0018] Furthermore, the fiber adhesive strips 202 are arranged in an interwoven mesh structure. The mesh structure of the fiber adhesive strips 202 has a large coverage area and a relatively uniform coverage when in use, which can effectively protect the stretch film.

[0019] Furthermore, the built-in rubber core 203 and the connecting sheet 204 are integrally molded structures. The built-in rubber core 203 is fixedly connected to the fiber rubber strip 202 through the connecting sheet 204. The built-in rubber core 203 is connected to the fiber rubber strip 202 through the connecting sheet 204, so that the part between the built-in rubber core 203 and the fiber rubber strip 202 is a hollow structure, which can better improve the anti-scratch and anti-cut effect.

[0020] Furthermore, the pressure-resistant layer 3 and the pressure-resistant cavity 7 are integrally formed. The width of the pressure-resistant cavity 7 is 0.2 mm. The pressure-resistant cavity 7 inside the pressure-resistant layer 3 is a sealed structure during use. The pressure-resistant layer 3 can effectively improve the pressure resistance of the stretch film through the pressure-resistant cavity 7, thereby improving the packaging protection of the stretch film. This can reduce the use of materials when packaging items and avoid waste.

[0021] Furthermore, the anti-corrosion composite layer 5 and the superhydrophobic coating 6 are integrally formed. When in use, the anti-corrosion composite layer 5 and the superhydrophobic coating 6 can play a role in preventing dirt and corrosion on the outer layer of the stretch film, which can prevent dirt from adhering to the surface of the stretch film and improve the protective effect of the stretch film packaging.

[0022] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, reinforcing layer 2 is laminated onto the LLDPE first base layer 1, compression-resistant layer 3 is laminated onto reinforcing layer 2, LLDPE second base layer 4 is laminated onto compression-resistant layer 3, and finally, anti-corrosion composite layer 5 with superhydrophobic coating 6 is laminated onto LLDPE second base layer 4. During use, reinforcing layer 2, through the fiber strips 202 within the reinforcing composite layer 201, enhances the overall scratch and cut resistance of the stretch film, improving its reliability in logistics packaging. It prevents scratches from sharp objects during packaging, avoids structural damage, and ensures overall integrity during the packaging process. The strength is enhanced to prevent breakage during transportation. The mesh structure of the fiber adhesive strip 202 provides a large and uniform coverage area, effectively protecting the stretch film. The pressure-resistant layer 3, through the pressure-resistant cavity 7, effectively improves the pressure resistance of the stretch film, enhancing its packaging protection. This reduces material usage and avoids waste when packaging items. The superhydrophobic coating 6 acts as a non-fouling agent on the outer layer of the stretch film, preventing dirt from adhering to its surface and improving the protective effect of the stretch film packaging.
