Description

Technical Field

[0001] This utility model relates to the field of PE packaging bag technology, specifically to a tear-resistant reinforced PE packaging bag. Background Technology

[0002] PE packaging bags refer to packaging bags made primarily of polyethylene. PE (polyethylene) is a non-toxic and harmless chemical substance, odorless and non-toxic, with excellent low-temperature resistance and chemical stability. These packaging bags are characterized by high transparency, good toughness, and waterproof and moisture-proof properties, and are therefore widely used in many fields such as food, medicine, cosmetics, clothing, and logistics, as well as for transporting and storing miscellaneous items.

[0003] Existing PE packaging bags are single-layer structures made of a single PE material. PE material itself has limited abrasion resistance, and the single-layer structure is even less effective at resisting tearing. For example, a food PE packaging bag disclosed in patent CN209667724U includes a front film and a back film. The left and right sides and the bottom of the front and back films are fixedly connected by heat fusion. The PE bag, which is mainly composed of the front film, back film and bottom film, does not have a reinforcing structure. Its tear resistance is poor, which makes it easy to tear when faced with large external forces, such as when filled with heavy items, squeezed or impacted. It is especially prone to damage after long-term use or when subjected to external forces, which reduces the service life of the packaging bag.

[0004] Therefore, it is necessary to invent a tear-resistant reinforced PE packaging bag to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tear-resistant reinforced PE packaging bag to solve the functional problems in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tear-resistant reinforced PE packaging bag, comprising a packaging bag body and a handle. The packaging bag body includes an outer PE layer, a nylon reinforcing layer, an aluminum foil layer, and an inner PE layer. A sealing strip is provided on one side of the top of the packaging bag body, extending along the top of the packaging bag body and covering part of the top area. Inner hook surface layer and inner rough surface layer are provided at the front and rear ends of the inner wall of the top of the packaging bag body. Side rough surface layer and side hook surface layer are provided on the left and right sides of the inner wall of the top of the packaging bag body. Outer hook surface layer is provided on the side of the sealing strip. Outer rough surface layer is provided on one side of the outer wall of the top of the packaging bag body. The positions of the outer hook surface layer and the outer rough surface layer correspond. Handles are threaded through the front and rear ends of the packaging bag body.

[0007] Preferably, the outer PE layer, nylon reinforcement layer, aluminum foil layer and inner PE layer are arranged sequentially from the outside to the inside. The multiple layers enhance the tear resistance of the packaging bag, making it less likely to break when subjected to large external forces, thus improving the durability and reliability of the packaging bag.

[0008] Preferably, the outer PE layer, nylon reinforcing layer, aluminum foil layer, and inner PE layer are tightly bonded by thermal bonding, and the edges at the connection points of the outer PE layer, nylon reinforcing layer, aluminum foil layer, and inner PE layer are sealed by heat sealing process. The thermal bonding process tightly bonds the materials of each layer together to form a whole, which improves the structural strength and stability of the packaging bag body and prevents separation between the layers. The heat sealing process can effectively prevent moisture, air, etc. from seeping into the interior of the packaging bag body from the edges, further enhancing the sealing performance of the packaging bag.

[0009] Preferably, the inner hook layer and the inner fleece layer cooperate to form a Velcro structure that can be repeatedly opened and closed. The extension length of the inner hook layer and the inner fleece layer matches the top width of the packaging bag body. The Velcro structure facilitates the opening and closing operation of the packaging bag body, and users can easily open and close the packaging bag.

[0010] Preferably, there are two side frayed surfaces and two side hook surfaces. The two side frayed surfaces are positioned close to the inner hook surface, and the two side hook surfaces are positioned close to the inner frayed surface. The side frayed surfaces and the inner hook surfaces are interlocked, which enhances the sealing of the top left and right sides of the packaging bag body.

[0011] Preferably, the outer hook layer and the outer fleece layer cooperate to form a Velcro structure that can be repeatedly opened and closed. The width of the outer fleece layer is adapted to the outer hook layer, and the cooperation between the outer hook layer and the outer fleece layer achieves complete sealing of the top of the packaging bag body.

[0012] Preferably, the carrying strap includes a first connecting segment and a second connecting segment. The connection points between the first connecting segment, the second connecting segment and the packaging bag body are bonded with reinforcing stickers by adhesive. The reinforcing stickers are located on the inner and outer walls of the packaging bag body, and the reinforcement stickers enhance the connection strength between the carrying strap and the packaging bag body.

[0013] Preferably, the carrying strap is provided with a silicone grip, and the outer surface of the silicone grip is provided with a silicone pad. The silicone grip provides users with a comfortable grip and reduces hand fatigue when carrying packaging bags for a long time.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The packaging bag body of this utility model adopts a multi-layer composite structure with an outer PE layer, a nylon reinforcing layer, an aluminum foil layer, and an inner PE layer arranged sequentially from the outside to the inside. The outer PE layer has good wear resistance and moisture resistance, and as the outermost layer, it can effectively resist the wear and moisture erosion of the external environment. The nylon reinforcing layer has high strength and toughness, which significantly enhances the overall tear resistance of the packaging bag, so that it can maintain the integrity of the structure and is not easy to break when facing large external forces. The aluminum foil layer not only has excellent barrier properties, but also increases the rigidity and strength of the packaging bag to a certain extent. The inner PE layer ensures chemical stability and hygiene when in contact with the items. The materials of each layer work together to improve the tear resistance of the packaging bag body.

[0016] 2. The inner hook layer, inner nap layer, side nap layer, side hook layer, outer hook layer, and outer nap layer of the packaging bag body of this utility model are all made of Velcro, which can be repeatedly opened and closed. The inner hook layer and the inner nap layer work together to form a basic seal on the front and rear ends of the top of the packaging bag. The side nap layer and the side hook layer further enhance the sealing of the left and right sides of the top of the packaging bag. The cooperation between the outer hook layer and the outer nap layer achieves a complete seal on the top of the packaging bag. This multi-layer sealing structure seals the opening of the packaging bag from multiple directions, effectively preventing the items from leaking from the opening of the packaging bag and greatly improving the sealing performance of the packaging bag.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figure 1-4 The illustrated tear-resistant reinforced PE packaging bag includes a bag body 1 and a handle 9. The bag body 1 includes an outer PE layer 101, a nylon reinforcing layer 102, an aluminum foil layer 103, and an inner PE layer 104. A sealing strip 2 is provided on one side of the top of the bag body 1, extending along the top of the bag body 1 and covering part of the top area. Inner hook surface layer 3 and inner fleece surface layer 4 are provided at both ends of the top inner wall of the bag body 1. Side fleece surface layer 5 and side hook surface layer 6 are provided on the left and right sides of the top inner wall of the bag body 1. The side of the mouth strip 2 is provided with an outer hook surface layer 7, and the top outer wall of the packaging bag body 1 is provided with an outer fleece surface layer 8. The outer hook surface layer 7 and the outer fleece surface layer 8 are positioned correspondingly. The front and rear ends of the packaging bag body 1 are provided with handles 9. The handles 9 include a first connecting section and a second connecting section. The connection between the first connecting section, the second connecting section and the packaging bag body 1 is glued with a reinforcing sticker 10. The reinforcing sticker 10 is located on the inner wall and the outer wall of the packaging bag body 1. The handles 9 are provided with a silicone grip 11, and the outer surface of the silicone grip 11 is provided with a silicone pad.

[0025] The carrying strap 9 makes it easy for users to carry the packaging bag body 1, improving the usability of the packaging bag body 1. The reinforcing sticker 10 enhances the connection strength between the carrying strap 9 and the packaging bag body 1, preventing the carrying strap 9 from falling off the packaging bag body 1 when subjected to large pulling force, thus improving the durability and safety of the packaging bag body 1. In addition, the silicone grip 11 not only provides users with a comfortable grip and reduces hand fatigue when carrying the packaging bag body 1 for a long time, but also has good anti-slip properties, which can increase the friction between the hand and the silicone grip 11 and prevent the packaging bag body 1 from slipping out of the hand.

[0026] The outer PE layer 101, nylon reinforcement layer 102, aluminum foil layer 103 and inner PE layer 104 are arranged sequentially from the outside to the inside. The outer PE layer 101, nylon reinforcement layer 102, aluminum foil layer 103 and inner PE layer 104 are tightly bonded by thermal bonding, and the edges at the connection between the outer PE layer 101, nylon reinforcement layer 102, aluminum foil layer 103 and inner PE layer 104 are sealed by heat sealing process.

[0027] The multi-layer structure consisting of an outer PE layer 101, a nylon reinforcing layer 102, an aluminum foil layer 103, and an inner PE layer 104 works together to enhance the structural strength of the packaging bag body 1, effectively improving its tear resistance. Furthermore, the layers are tightly bonded together using a thermal bonding process, ensuring that the multi-layer materials form a solid whole. At the same time, heat sealing is applied to the edges of the joints between the layers to prevent moisture and air from seeping in, further enhancing the sealing performance of the packaging bag body 1 and ensuring that the contents are not affected by the external environment.

[0028] The inner hook layer 3 and the inner fleece layer 4 work together to form a Velcro structure that can be repeatedly opened and closed. The extension length of the inner hook layer 3 and the inner fleece layer 4 matches the top width of the packaging bag body 1. There are two side fleece layers 5 and two side hook layers 6. The two side fleece layers 5 are set close to the inner hook layer 3, and the two side hook layers 6 are set close to the inner fleece layer 4. The side fleece layers 5 and the inner hook layer 3 hook each other, and the side hook layers 6 and the inner fleece layer 4 hook each other. The outer hook layer 7 and the outer fleece layer 8 work together to form a Velcro structure that can be repeatedly opened and closed. The width of the outer fleece layer 8 is adapted to the outer hook layer 7.

[0029] The inner hook layer 3 and inner fleece layer 4, the side fleece layer 5 and side hook layer 6, and the outer hook layer 7 and outer fleece layer 8 all adopt a Velcro structure, which can be repeatedly opened and closed. Users can easily open and close the packaging bag body 1 as needed without the need for additional tools or complicated operations, which improves the convenience of use. Moreover, the Velcro structures work together to form a tight sealing system, which effectively prevents external dust, moisture and other substances from entering the packaging bag body 1 and protects the items inside the packaging from contamination and damage.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figure 1-4 When using this utility model, first locate the outer fur layer 8 on one side of the top outer wall of the packaging bag body 1 and the outer hook layer 7 on the side of the sealing strip 2. Gently pinch the edges of the outer hook layer 7 and the outer fur layer 8 with your fingers and slowly pull them apart to separate them. At this time, the top area covered by the sealing strip 2 is opened. Next, similarly pinch the edges of the inner hook layer 3 and the inner fur layer 4 with your fingers and pull them apart to separate them. When the inner hook layer 3 and the inner fur layer 4 are separated, hold the side fur layer 5 and the side hook layer 6 with your hands and gently separate them from the inner hook layer 3 and the inner fur layer 4 along their bonding direction. After they are completely separated, the top of the packaging bag body 1 is completely opened, and the user can easily take out or put in items.

[0032] After the items have been placed in or removed, the sealing process begins. First, align and attach the two side napped layers 5 on the left and right sides of the top inner wall of the packaging bag with the adjacent inner hook layer 3, and align and attach the two side hook layers 6 with the adjacent inner napped layer 4. Press with your fingers to ensure that the side napped layers 5 and inner hook layers 3, and the side hook layers 6 and inner napped layers 4, are tightly hooked together. Next, align the inner hook layers 3 and inner napped layers 4 at the front and rear ends of the top inner wall of the packaging bag body 1, and gently press with your fingers to make them interlock, achieving initial sealing. First, seal the bag to prevent leakage from the top, front, back, left, and right sides. Finally, align the outer hook layer 7 on the side of the sealing strip 2 with the outer rough layer 8 on the top outer wall of the packaging bag body 1, and gently press to make them fit tightly together, completing the complete sealing of the top of the packaging bag body 1. At this time, the Velcro structures cooperate with each other to form a tight sealing system. Through the above opening and sealing operation steps, users can easily use this tear-resistant reinforced PE packaging bag, while ensuring the sealing performance of the packaging bag body 1 and protecting the safety of the contents.
