Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging bag technology, and in particular to a tensile-resistant packaging bag. Background Technology
[0002] Packaging bags are bags used to package various products, mainly for facilitating the transportation and storage of goods during the production and distribution process.
[0003] In the field of packaging technology, traditional packaging bags have many shortcomings. When carrying heavy objects, the edges and handles of ordinary packaging bags are prone to tearing due to excessive force, causing items to fall or leak, which cannot meet the actual use needs. Although some existing packaging bags improve strength by increasing thickness or adopting multi-layer composite structures, this not only increases production costs but may also reduce the flexibility of the packaging bag, affecting the user experience and making it less practical. Therefore, it is necessary to redesign a tensile-resistant packaging bag to address the above problems. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tensile-resistant packaging bag.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A tensile-resistant packaging bag includes a packaging bag body, a tensile-resistant layer, and a heat-insulating layer. A reinforcing seal is fixedly installed on the upper surface of the packaging bag body. Multiple rotating pad frames are fixedly installed on the upper surface of the reinforcing seal. A handle is fixedly installed inside the two rotating pad frames on the same side through a rotating mechanism. Side pockets are fixedly installed on the outer walls of both sides of the packaging bag body. Multiple rubber strips are fixedly installed on the inner walls of both sides of the packaging bag body.
[0007] Preferably, the rotating mechanism includes a rotating rod rotatably mounted inside the rotating pad frame, and the handle is fixedly mounted on the outer wall of the rotating rod.
[0008] Preferably, a placement pad is fixedly installed on the bottom wall of the inner part of the packaging bag, and the placement pad is made of rubber.
[0009] Preferably, each rubber strip is evenly distributed at equal intervals and of equal size, and each rubber strip is semi-circular in shape.
[0010] Preferably, the tensile layer is disposed between the packaging bag body and the insulation layer, and the tensile layer is made of polyester fiber.
[0011] Preferably, the insulation layer is disposed on the inner wall of the packaging bag body, and the insulation layer is made of polyethylene.
[0012] The beneficial effects of this utility model are:
[0013] 1. By incorporating components such as reinforced edge sealing, handles, and tensile strength layers, the packaging bag's tensile strength is enhanced from three aspects: the bag opening, handles, and the overall bag body. Compared to traditional packaging bags, it can withstand greater tensile force, effectively preventing tearing and making it suitable for carrying heavier items.
[0014] 2. By incorporating components such as side pockets, rubber strips, and placement pads, the side pocket design increases storage space, making it convenient to store small items. The internal rubber strips and placement pads cushion and secure the items, reducing shaking and collisions during transportation, protecting the items, and enhancing the overall practicality of the packaging bag.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5A tensile-resistant packaging bag includes a bag body 1, a tensile-resistant layer 9, and an insulation layer 10. A reinforcing edge seal 2 is fixedly installed on the upper surface of the bag body 1. Multiple rotating pad frames 3 are fixedly installed on the upper surface of the reinforcing edge seal 2. Handles 5 are fixedly installed inside two rotating pad frames 3 on the same side via a rotating mechanism. The rotating mechanism includes a rotating rod 4 rotatably installed inside the rotating pad frame 3. Handles 5 are fixedly installed on the outer wall of the rotating rod 4. Handles 5 are made of high-strength woven material, are sturdy and durable, and can withstand the weight of heavy items. Side pockets 6 are fixedly installed on both outer walls of the bag body 1. A placement pad 7 is fixedly installed on the inner bottom wall of the bag body 1. The placement pad 7 is made of rubber with a textured surface, which not only provides anti-slip properties but also cushions items when placed inside, protecting them and reducing impact on the bottom of the bag. Multiple rubber rods are fixedly installed on both inner walls of the bag body 1. The rubber strips 8 are evenly distributed at equal intervals and of the same size. Each rubber strip 8 is semi-circular in shape. This layout and shape design allows the rubber strips 8 to form a buffer protective layer inside the packaging bag. When the item is placed in the packaging bag, the rubber strips 8 can conform to the item through elastic deformation, effectively reducing the shaking and collision of the item during transportation. The tensile layer 9 is set between the packaging bag body 1 and the insulation layer 10. The tensile layer 9 is made of polyester fiber. Polyester fiber has excellent toughness and strength, which can greatly improve the overall tensile performance of the packaging bag, making the packaging bag less prone to deformation and damage when loaded with heavy objects. The insulation layer 10 is set on the inner wall of the packaging bag body 1. The insulation layer 10 is made of polyethylene. Polyethylene material has good heat insulation performance, which can effectively block the entry of external heat or the loss of internal heat, and maintain the temperature stability inside the packaging bag. It is suitable for packaging items with temperature requirements.
[0023] When using this utility model, the items to be packaged are placed inside the packaging bag body 1. At this time, the rubber strip 8 on the inner wall will fit tightly against the outline of the items due to its elastic deformation. Since the rubber strip 8 is semi-circular and evenly distributed, it can not only effectively buffer the collision between the items and the bag, but also use the friction generated by multi-point contact to firmly restrict the items in the designated area inside the bag, preventing them from shifting due to shaking during handling and transportation. The placement pad 7 is made of rubber, which is soft and has a certain anti-slip performance. It can provide uniform support for the items placed at the bottom, preventing sharp or heavy items from directly squeezing the bottom of the bag, and further protecting the packaging bag body 1 from being punctured or torn.
[0024] When the packaging bag needs to be moved, hold the handle 5, and the rotating rod 4 will rotate flexibly within the rotating pad frame 3. It will automatically adjust the angle according to the direction of the force applied by the hand, so that the handle 5 is always in the most reasonable position for force. This adaptive rotation design can effectively prevent the handle 5 from breaking due to stress concentration at the connection between the handle 5 and the bag body. At the same time, the reinforced edge seal 2 will evenly distribute the tensile force transmitted by the handle 5 to the upper surface of the packaging bag body 1. Combined with the tensile layer 9 of polyester fiber, it forms an all-round tensile protection system from the bag opening to the bag body. Even when carrying heavy items, the packaging bag can withstand greater tensile force, significantly improving the overall structural strength.
[0025] If the package contains small, loose items, the side pockets 6 on both sides can be used for categorized storage. The design of the side pockets 6 not only increases the storage space of the packaging bag but also prevents small items from being squeezed against larger items in the main bag, making them easy to access quickly. For items that need to be kept warm, such as fresh food or medicine, the polyethylene insulation layer 10 plays a key role. It can effectively block the conduction of external heat and slow down the rate of temperature change inside the bag. Combined with the closed buffer space formed by the rubber strip 8 and the padding 7, it further reduces heat exchange caused by air flow, thereby maintaining a stable temperature environment inside the packaging bag for a long time and ensuring that the quality of the items is not affected. After use, the handle 5 can be folded up to the position where it fits against the reinforced edge 2 by rotating the rod 4, reducing the overall volume of the packaging bag, making it easy to fold and store, saving storage space, and also preventing the handle 5 from being subjected to unnecessary wear when not in use, thus extending its service life.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
