Description

Technical Field

[0001] This utility model relates to the field of stretch film technology, and in particular to a stretch film with an anti-slip reinforcement structure. Background Technology

[0002] PE stretch film is an advanced packaging material made primarily of polyethylene, offering numerous significant advantages. Firstly, its superior physical properties, including high strength, high elasticity, and excellent tear resistance, allow it to tightly wrap goods, effectively preventing loosening, damage, or deformation during transportation, making it particularly suitable for the stable packaging of palletized goods. Secondly, PE stretch film exhibits excellent weather resistance, withstanding low temperatures, high temperatures, and high pressure environments, adapting to the storage and transportation needs under diverse climatic conditions. Furthermore, by adding tackifiers or using metallocene catalysts to enhance self-adhesion, the film adheres tightly to the surface of goods, reducing dust and sand contamination, while also lowering wrapping noise and improving packaging efficiency. Economically, PE stretch film can save over 50% in material costs compared to traditional packaging, eliminating the need for heat shrink equipment, resulting in lower energy consumption and significantly reducing labor intensity and packaging expenses for businesses. Its ultra-thin design and high extensibility further reduce material usage, while optimizing storage space through tight wrapping. Environmentally, PE material is non-toxic and recyclable, gradually replacing the more polluting PVC film, aligning with modern green packaging trends.

[0003] Existing stretch film has shortcomings in use. It lacks anti-slip reinforcement structure, and its overall anti-slip effect is not ideal. At the same time, its radial tensile strength is also not ideal.

[0004] In view of this, the inventors hope to optimize and improve existing stretch films and provide a stretch film with an anti-slip reinforcement structure. Summary of the Invention

[0005] The purpose of this invention is to overcome the aforementioned problems in traditional technology and provide a wrapping film with an anti-slip and reinforced structure.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A spiral wound film with an anti-slip reinforcement structure includes a base layer, an elastic mesh layer, and an anti-slip layer: The base layer is made of PE material; The elastic mesh layer is disposed between the base layer and the anti-slip layer. The elastic mesh layer is composed of intersecting transverse and longitudinal elastic ribs and is made of thermoplastic elastomer material. The anti-slip layer consists of an anti-slip strip and anti-slip reinforcing strips arranged side by side on its outer side. The anti-slip reinforcing strips have several anti-slip grooves evenly distributed along their length. The anti-slip layer is made of thermoplastic elastomer material.

[0007] Furthermore, in the above-mentioned wrapping film with anti-slip reinforcement structure, the thickness of the base layer is 15-25 μm; the thickness of the elastic ribbed layer is 8-15 μm; and the thickness of the anti-slip strip portion in the anti-slip layer is 5-10 μm.

[0008] Furthermore, in the aforementioned wrapping film with anti-slip reinforcement structure, the base layer is made of a blend of linear low-density polyethylene, high-pressure low-density polyethylene, and metallocene polyethylene, wherein linear low-density polyethylene accounts for 50-65%, high-pressure low-density polyethylene accounts for 15-25%, and the remainder is metallocene polyethylene.

[0009] Furthermore, in the aforementioned wrapping film with anti-slip reinforcement structure, the mesh of the elastic rib layer is filled with adhesive.

[0010] Furthermore, in the above-mentioned wrapping film with anti-slip reinforcement structure, the width of the transverse elastic ribs and the longitudinal elastic ribs is 0.5-1.5 mm, the thickness is 0.05-0.2 mm, and the stagger angle of the transverse elastic ribs and the longitudinal elastic ribs is 60-90 degrees.

[0011] Furthermore, in the above-mentioned wrapping film with anti-slip reinforcement structure, the width of the anti-slip reinforcement strip is 2-5mm, and the spacing between adjacent anti-slip reinforcement strips is 3-8mm.

[0012] Furthermore, in the above-mentioned anti-slip reinforced wrapping film, the depth of the anti-slip groove is 0.1-0.3 mm, the length is 1-3 mm, and the spacing between adjacent anti-slip grooves is 0.5-2 mm.

[0013] Furthermore, in the aforementioned wrapping film with anti-slip reinforcement structure, the elastic rib layer is made of thermoplastic polyurethane elastomer material.

[0014] The beneficial effects of this utility model are: 1. Improved anti-slip effect: An anti-slip layer is set up, consisting of an anti-slip strip and anti-slip reinforcing strips arranged side by side on the outer side. The anti-slip reinforcing strips are evenly distributed with several anti-slip grooves along the length direction, which enhances the overall anti-slip performance and solves the problem of unsatisfactory anti-slip effect of existing stretch film.

[0015] 2. Enhanced radial tensile strength: An elastic mesh layer is set, which is composed of intersecting transverse and longitudinal elastic ribs. It is made of thermoplastic elastomer material and the mesh is filled with adhesive, which improves the radial tensile strength of the wrapping film and makes up for the deficiency of insufficient radial tensile strength of existing wrapping films.

[0016] 3. Excellent base layer performance: The base layer is made of linear low-density polyethylene, high-pressure low-density polyethylene and metallocene polyethylene blend, which has the advantages of PE stretch film such as high strength, high elasticity, excellent tear resistance, excellent weather resistance, good self-adhesion, good economy and environmental protection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-6 As shown, this embodiment provides a wrapping film with an anti-slip reinforcement structure, including a base layer 1, an elastic ribbed layer 2, and an anti-slip layer 3, wherein the elastic ribbed layer 2 is disposed between the base layer 1 and the anti-slip layer 3.

[0022] In this embodiment, the base layer 1 is made of PE material; specifically, the base layer 1 is made of a blend of linear low-density polyethylene, high-pressure low-density polyethylene and metallocene polyethylene, wherein linear low-density polyethylene accounts for 50-65%, high-pressure low-density polyethylene accounts for 15-25%, and the remainder is metallocene polyethylene.

[0023] In this embodiment, the elastic mesh layer 2 is composed of crisscrossing transverse elastic ribs 201 and longitudinal elastic ribs 202. The elastic mesh layer 2 is made of a thermoplastic elastomer material, such as thermoplastic polyurethane elastomer. The mesh of the elastic mesh layer 2 is filled with adhesive. The width of the transverse elastic ribs 201 and the longitudinal elastic ribs 202 is 0.5–1.5 mm, the thickness is 0.05–0.2 mm, and the intersection angle between the transverse and longitudinal elastic ribs is 60–90 degrees.

[0024] In this embodiment, the anti-slip layer 3 is composed of an anti-slip strip 301 and anti-slip reinforcing strips 302 arranged side by side on its outer side. The anti-slip reinforcing strips 302 are evenly distributed with a plurality of anti-slip grooves 303 along their length direction. The anti-slip layer 3 is made of thermoplastic elastomer material.

[0025] In this embodiment, the thickness of the base layer 1 is 15-25 μm; the thickness of the elastic ribbed layer 2 is 8-15 μm; and the thickness of the anti-slip strip 301 in the anti-slip layer 3 is 5-10 μm.

[0026] In this embodiment, the width of the anti-slip reinforcement strip 302 is 2-5mm, and the spacing between adjacent anti-slip reinforcement strips 302 is 3-8mm.

[0027] In this embodiment, the depth of the anti-slip groove 303 is 0.1-0.3 mm, the length is 1-3 mm, and the spacing between adjacent anti-slip grooves 303 is 0.5-2 mm.

[0028] One specific application of this embodiment is: In warehousing and logistics scenarios, large quantities of goods are stacked and transported on pallets. When using the stretch film of this embodiment to package palletized goods, the PE material blend formula of the base layer gives it high strength, high elasticity, and tear resistance, which can tightly wrap goods of different shapes and sizes, preventing the goods from loosening, breaking, or deforming due to bumps and collisions during transportation; the elastic mesh layer, through its crisscrossing elastic rib structure and filled adhesive, significantly improves the radial tensile strength of the stretch film, ensuring that the packaging integrity is maintained even when subjected to large external forces during goods stacking, handling, or long-distance transportation; the anti-slip strips and anti-slip reinforcement strips (including anti-slip grooves) of the anti-slip layer enhance the friction between the stretch film and the surface of the goods and the pallet, preventing the goods from sliding or shifting during transportation, which is especially suitable for transportation on inclined roads or multi-layer stacking scenarios. In addition, the weather resistance of this stretch film enables it to adapt to the storage and transportation needs under different climatic conditions, its self-adhesiveness reduces dust pollution and wrapping noise, and its ultra-thin design and high ductility further optimize material usage and storage space utilization, meeting the requirements of modern logistics for efficient and environmentally friendly packaging materials.
