Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and more specifically to a biodegradable polymer packaging bag. Background Technology

[0002] Packaging bags are an extremely common and widely used form of flexible packaging, primarily used to contain, protect, preserve, transport, and display products, while also conveying brand and information. They are made from various materials and vary in shape, size, and function. Through material selection and structural design, they meet the needs of different scenarios, facilitating the transportation and storage of goods during production and distribution. They are widely used in daily life and industrial production. With advancements in materials science and technology, and increased environmental awareness, packaging bags are rapidly developing towards lighter weight, more functional, intelligent, and sustainable designs. Choosing the right type and material for packaging bags is crucial to product success. Most existing packaging bags are made of plastic, which is non-degradable and a source of white pollution. Therefore, biodegradable polymer packaging bags are now widely used due to their ease of degradation and decomposition.

[0003] For example, a biodegradable plastic packaging bag with prior art publication number CN222433062U has good waterproof and antibacterial effects through the interaction of a biodegradable base layer, a printing layer, a waterproof layer, an antibacterial layer and a protective layer. At the same time, it also has the advantage that the packaging bag can be quickly degraded by the outside after being discarded, without causing a large amount of white pollution. It accelerates the degradation speed of the polymer packaging bag and can play an environmental protection role.

[0004] However, the existing technology described above still has the following problems in use: when items are placed inside the packaging bag for carrying, the items will shake with the user's hand movements, and this shaking will cause the packaging bag to collide with it, resulting in damage and affecting its service life. Based on this, this utility model provides a biodegradable polymer packaging bag that can improve its service life. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides a biodegradable polymer packaging bag. By setting a rubber pressure plate inside the main body of the packaging bag, the bag is used to compress the items to improve stability and prevent damage to the items caused by shaking and impacting the main body of the packaging bag. At the same time, the rubber pressure plate is soft and can adapt to the deformation of the main body of the packaging bag without damaging the inner wall of the main body of the packaging bag. In addition, two reinforcing wires are also provided inside the main body of the packaging bag to support the entire main body of the packaging bag, thereby further improving the strength of the main body of the packaging bag and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biodegradable polymer packaging bag, comprising a main body of the packaging bag, wherein the main body of the packaging bag has two symmetrically distributed reinforcing holes inside, the tops of the two reinforcing holes extending to the top surface of the main body of the packaging bag, and reinforcing wires fixedly installed inside the two reinforcing holes, with a handle connected to the top of the two reinforcing wires, the outer wall of the handle being fixedly fitted with a rubber sleeve, and a rubber pressure plate inside the main body of the packaging bag, the top of the rubber pressure plate having a rectangular groove, and two mounting blocks fixedly installed inside the rectangular groove, with a handle rotatably provided between the two mounting blocks.

[0007] In a preferred embodiment, a dust plug is hinged inside the rectangular groove and is located above the handle. The dust plug can seal the rectangular groove and prevent it from being blocked by debris.

[0008] In a preferred embodiment, a lever is fixedly provided on the top of the dust plug, and a slot adapted to the lever is provided on the top of the rubber pressure plate. The lever facilitates the opening of the dust plug by the operator, and after the dust plug is opened, the lever is inserted into the slot to keep the dust plug stable and prevent it from shaking.

[0009] In a preferred embodiment, both sides of the bottom end of the two carrying straps are provided with connecting holes adapted to the reinforcing wires. The top of the reinforcing wires is inserted into the connecting holes and fixed by pins. When the main body of the packaging bag is damaged, the pins can be removed to separate the carrying straps from the reinforcing wires, making it easier to recycle the reinforcing wires and reduce resource waste.

[0010] In a preferred embodiment, both rubber sleeves have multiple evenly distributed rubber protrusions processed on their outer walls. Processing multiple rubber protrusions on the rubber sleeves can increase the friction on the surface of the rubber sleeves, thereby improving the anti-slip properties.

[0011] In a preferred embodiment, the main body of the packaging bag is made of polyhydroxyalkanoate, which has excellent toughness, excellent biocompatibility, and can be degraded by microorganisms in the natural environment. The outer and inner walls of the main body of the packaging bag are coated with a waterproof coating, specifically carnauba wax waterproof coating, which has excellent heat resistance and high hardness and abrasion resistance. This allows the main body of the packaging bag to be waterproof, heat-resistant, and abrasion-resistant.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model improves stability by setting a rubber pressure plate inside the main body of the packaging bag, which compresses the items and prevents them from being damaged by shaking and impacting the main body of the packaging bag. At the same time, the rubber pressure plate is soft and can adapt to the deformation of the main body of the packaging bag without damaging the inner wall of the main body of the packaging bag. In addition, two reinforcing wires are also provided inside the main body of the packaging bag to support the entire main body of the packaging bag, thereby further improving the strength of the main body of the packaging bag.

[0014] 2. The main body of the packaging bag is made of polyhydroxyalkanoates. Polyhydroxyalkanoates have excellent toughness and biocompatibility. They can be degraded by microorganisms in the natural environment. Waterproof coatings are applied to both the outer and inner walls of the main body of the packaging bag, which can improve the waterproofness of the main body of the packaging bag and thus extend its service life.

[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. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Refer to the instruction manual appendix Figures 1-5This utility model provides a biodegradable polymer packaging bag, including a packaging bag body 1. The packaging bag body 1 is made of polyhydroxyalkanoate, which has excellent toughness, excellent biocompatibility, and can be degraded by microorganisms in the natural environment. The outer and inner walls of the packaging bag body 1 are coated with a waterproof coating, such as carnauba wax, which has a melting point as high as 83-86℃ and has excellent heat resistance. The waterproof membrane has high hardness and abrasion resistance, which enables the packaging bag body 1 to be waterproof, heat-resistant, and abrasion-resistant.

[0023] The main body 1 of the packaging bag has two symmetrically distributed reinforcing holes 2 inside. The top of each reinforcing hole 2 extends to the top surface of the main body 1 of the packaging bag. A reinforcing wire 3 is fixed inside each reinforcing hole 2. The reinforcing wire 3 can be made of steel wire or carbon fiber wire, both of which have high strength and bending ability, so as to play a reinforcing role inside the main body 1 of the packaging bag. The top of each reinforcing wire 3 is connected to a carrying strap 4. Furthermore, there are connecting holes 13 on both sides of the bottom end of each carrying strap 4 that are adapted to the reinforcing wire 3. The top of the reinforcing wire 3 is inserted into the connecting hole 13 and fixed by a pin 14. The pin 14 can be made of stainless steel. Stainless steel has the advantages of high strength and corrosion resistance, so it can improve the connection between the reinforcing wire 3 and the carrying strap 4. The design is detachable, which makes it easy to separate the carrying strap 4 and the reinforcing wire 3 later, so as to facilitate the recycling of the reinforcing wire 3.

[0024] The main body 1 of the packaging bag is provided with a rubber pressure plate 6 inside. A rectangular groove 7 is provided on the top of the rubber pressure plate 6. Two mounting blocks 8 are fixedly provided inside the rectangular groove 7. A handle 9 is rotatably provided between the two mounting blocks 8. A dust plug 10 is hinged inside the rectangular groove 7 and is located above the handle 9.

[0025] In actual use, a rubber pressure plate 6 is placed inside the main body 1 of the packaging bag. When the user places an item inside the main body 1 of the packaging bag, they can press down on the rubber pressure plate 6 to compact the item, thereby improving the stability of the item and preventing it from shaking and hitting the main body 1 of the packaging bag, which could cause damage. When the user needs to take out the item, they can first open the dust plug 10 from the rectangular groove 7, and then grasp the handle 9 to remove the rubber pressure plate 6 from inside the main body 1 of the packaging bag. Since the rubber pressure plate 6 is soft, it can adapt to the deformation of the main body 1 of the packaging bag without damaging the inner wall of the main body 1 of the packaging bag. In addition, two reinforcing wires 3 are set inside the main body 1 of the packaging bag. When the user holds the two handles 4, the two reinforcing wires 3 can support the entire main body 1 of the packaging bag, thereby improving the strength of the main body 1 of the packaging bag.

[0026] like Figure 2 and Figure 3As shown, a lever 11 is fixedly provided on the top of the dust plug 10, and a slot 12 adapted to the lever 11 is provided on the top of the rubber pressure plate 6. The lever 11 is provided to facilitate the opening of the dust plug 10 by the operator. After the dust plug 10 is opened, the lever 11 is inserted into the slot 12, which can keep the dust plug 10 stable and prevent the dust plug 10 from shaking.

[0027] like Figure 1 As shown, a rubber sleeve 5 is fixedly fitted on the outer wall of the handle 4. Both rubber sleeves 5 have multiple evenly distributed rubber protrusions 15 processed on their outer walls. The rubber sleeves 5 are soft in texture and can prevent the user's hands from being cut when the user grips the handle 4. Multiple rubber protrusions 15 are processed on the rubber sleeves 5. The rubber protrusions 15 are the same as the rubber sleeves 5 and can increase the friction on the surface of the rubber sleeves 5, thereby improving the anti-slip properties. At the same time, the rubber protrusions 15 are soft in texture and can reduce the pressure on the hands to a certain extent.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
