Description

Technical Field

[0001] This utility model relates to the field of coated woven bags, specifically to high-toughness coated woven bags for packaging. Background Technology

[0002] Laminated woven bags, a common packaging material, are widely used in industries such as chemical, agricultural, and construction, primarily for carrying powdered, granular, or other items. With the continuous development of modern logistics and transportation demands, the durability, tensile strength, waterproofing, and moisture resistance of traditional woven bags have gradually become insufficient to meet increasingly stringent requirements. Therefore, laminated woven bags have emerged and rapidly gained application in various fields. By combining the woven bag body with a laminating layer, laminated woven bags significantly improve the waterproofing, moisture resistance, and UV resistance of the bags, greatly overcoming the limitations of traditional woven bags in transportation and storage.

[0003] However, the traditional design of a single-layer braided layer combined with an external single-layer coating layer has some obvious shortcomings, as follows:

[0004] Insufficient structural strength and tensile strength: Traditional single-layer woven designs typically employ a relatively simple weaving structure. While this provides some strength, the limited number of layers and simple weaving method result in relatively weak tensile and tear resistance, making them prone to damage or deformation when loaded with heavy objects or during long-term transportation. This structure lacks sufficient strength to withstand high-intensity external pressure and impacts, especially in situations requiring the support of heavy items. Its insufficient tensile strength directly affects the stability and reliability of the packaging.

[0005] Limited protective performance and inability to adapt to changing environments: Traditional laminated woven bags mostly use a single-layer outer coating. While this provides some waterproofing, the limitations of the outer coating material and thickness make it difficult to use long-term in harsh environments (such as strong ultraviolet radiation or humid conditions). Furthermore, its UV protection is limited, easily leading to aging and embrittlement of the woven bag material or damage to the contents. In addition, a single outer coating layer cannot effectively cope with changes in different environmental conditions, resulting in a significant reduction in the protective effect of the packaging bag under some extreme conditions.

[0006] Lack of reinforced design and limited load-bearing capacity: Traditional single-layer woven bags often lack additional reinforcement measures, making them prone to rupture or deformation under heavy loads. Especially during transportation, woven bags may suffer structural damage due to excessive external pressure. The stability and strength of woven bags cannot be effectively guaranteed, particularly when packaging heavy or bulky goods, increasing the risks during transport.

[0007] Poor user experience: Traditional woven bags often lack design considerations for handling, with poorly positioned handles or no additional support, making them inconvenient to handle, especially when loading and unloading items. Handlers may encounter situations where the bag is unstable or difficult to lift. While they may meet packaging requirements to some extent, their convenience and comfort in actual use are significantly reduced.

[0008] Therefore, this solution proposes a high-toughness coated woven bag to solve the above problems. Utility Model Content

[0009] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a high-toughness packaging coated woven bag.

[0010] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: a high-toughness packaging coated woven bag, comprising a woven bag body, characterized in that the woven bag body is composed of a multi-layer composite structure, and a reinforcing lifting component is attached to the outside of the woven bag body. The reinforcing lifting component includes annular reinforcing strips located at the lower one-sixth and upper one-third positions of the woven bag body, and U-shaped reinforcing strips connecting the upper and lower annular reinforcing strips on both sides. The U-shaped reinforcing strips on both sides are wrapped around the outside of the woven bag body, and lifting handles are provided on the left and right sides of the upper and lower annular reinforcing strips.

[0011] Preferably, the multi-layer composite structure inside the woven bag body specifically includes a first woven layer and a second woven layer distributed on the inner and outer sides, an adhesive layer is provided between the first woven layer and the second woven layer, an inner coating layer is provided on the inner side of the first woven layer, and an outer coating layer is provided on the outer side of the second woven layer.

[0012] Preferably, the woven strips inside the first woven layer are distributed intersecting along the warp and weft lines.

[0013] Preferably, the second woven layer is made of multiple vertically intersecting woven strips, with the angle between the intersecting woven strips and the warp and weft lines set at 45°.

[0014] Preferably, both the first and second braided layers are made of PP material.

[0015] Preferably, the adhesive layer is made of hot melt adhesive.

[0016] Preferably, the outer coating layer is made of polyethylene.

[0017] Preferably, the inner coating layer is made of polyester material.

[0018] The beneficial effects of this utility model are reflected in:

[0019] Enhanced structural strength and tensile properties: The woven bag body consists of a two-layer composite structure, with the first and second woven layers fixed together by an adhesive layer. This two-layer design ensures strength while also improving tensile and tear resistance. The first woven layer uses an interlaced weave to ensure internal strength, while the second woven layer, with its 45° angled design, further enhances the bag's tensile strength.

[0020] Excellent corrosion and moisture resistance: The inner polyester coating effectively enhances the corrosion resistance and moisture resistance of the woven bag, allowing it to maintain good performance even in humid environments. Suitable for transporting and storing items susceptible to moisture and corrosion.

[0021] Superior waterproof and UV protection: The outer polyethylene coating provides excellent waterproofing, protecting the contents from external moisture. Simultaneously, the coating effectively blocks UV radiation, reducing material aging and damage to the contents caused by UV rays, making it particularly suitable for outdoor or direct sunlight environments.

[0022] High-strength lifting design: The reinforced lifting components include both circular and U-shaped reinforcing straps, carefully designed to enhance the lifting strength of the woven bag and ensure it can withstand greater loads during transportation and handling. In particular, the U-shaped reinforcing strap design effectively improves the overall stability of the woven bag, while preventing potential deformation during transport.

[0023] Convenient user experience: The handles on both sides of the woven bag make it easy for users to lift and move the bag, especially when loading heavy items. The handles improve the ease and comfort of operation and avoid difficulties in moving the bag due to excessive weight or unstable shape.

[0024] Strong environmental adaptability: This woven bag not only maintains good performance in environments with strong ultraviolet radiation, humidity, and corrosiveness, but its high toughness and long-term durability also enable it to adapt to various transportation and storage needs, making it especially suitable for material packaging in the chemical, agricultural, and construction industries.

[0025] In summary, by optimizing material selection and structural design, this high-toughness coated woven bag not only possesses excellent moisture-proof, waterproof, UV-resistant, and corrosion-resistant properties, but also exhibits high tensile and tear resistance, meeting the demands of modern logistics and transportation for packaging bags with high strength, durability, and environmental adaptability. The reinforced lifting mechanism enhances overall stability and ease of handling, enabling the woven bag to demonstrate extremely high performance and reliability in practical applications. Therefore, this designed woven bag not only effectively protects goods but also reduces losses during transportation, improves work efficiency, and has broad application prospects.

[0037] Please refer to the instruction manual appendix. Figures 1-3This utility model provides a high-toughness coated woven bag, which mainly consists of two parts: a woven bag body and a reinforcing lifting element. The woven bag body 1 is composed of a multi-layer composite structure, with a reinforcing lifting element 2 attached to the outer side.

[0038] Composite structure of woven bag body:

[0039] The woven bag body 1 consists of two layers: a first woven layer 11 and a second woven layer 12. The first woven layer 11 and the second woven layer 12 are fixed together by an adhesive layer 15. The adhesive layer 15 is made of hot melt adhesive, which ensures a strong bond between the two woven layers.

[0040] The first woven layer 11 is located on the inside of the woven bag and uses a woven strip with warp and weft threads intersecting to ensure its structural strength and tensile properties.

[0041] The second woven layer 12 is located on the outside of the woven bag and is made of multiple vertically intersecting woven strips. The angle between these woven strips and the warp and weft threads is set at 45° to improve the tensile strength and durability of the woven bag.

[0042] Configuration of inner and outer coating layers:

[0043] An inner lining layer 13, made of polyester material, is provided on the inner side of the first woven layer 11. The main function of the inner lining layer 13 is to improve the corrosion resistance and moisture resistance of the woven bag.

[0044] The outer side of the second woven layer 12 is provided with an outer coating layer 14, which is made of polyethylene. The outer coating layer 14 has excellent waterproof and UV protection functions, ensuring that the woven bag can be used in different environmental conditions.

[0045] Reinforced lifting component design:

[0046] The reinforcing lifting component 2 includes annular reinforcing straps 21 and U-shaped reinforcing straps 22. The annular reinforcing straps 21 are respectively positioned at the lower one-sixth and upper one-third of the woven bag body 1 to enhance the lifting strength of the woven bag. The U-shaped reinforcing straps 22 connect the two sides between the upper and lower annular reinforcing straps 21 and are wrapped around the outside of the woven bag body 1 on both sides.

[0047] The U-shaped reinforcing straps 22 on both sides effectively improve the overall stability of the woven bag and provide additional support.

[0048] Lifting handles 23 are provided on both the left and right sides of the upper and lower ring reinforcing strips 21, making it convenient for users to lift and move the woven bags.

[0049] In this embodiment, both the first woven layer 11 and the second woven layer 12 are made of PP polypropylene material, which has high tensile strength and tear resistance, ensuring the high strength and long service life of the woven bag.

[0050] The adhesive layer 15 is made of hot melt adhesive, which can effectively bond the first braided layer and the second braided layer together.

[0051] The inner coating layer 13 is made of polyester PET material, and the outer coating layer 14 is made of polyethylene PE material. Both have strong waterproof and moisture-proof properties and can adapt to the use requirements under various environmental conditions.
