Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, and more specifically, to a high-speed, easily degradable packaging bag. Background Technology

[0002] Packaging bags are common containers used in daily life and production for loading, protecting, and transporting goods. They are widely used in food, daily necessities, fresh produce, industrial products, and many other fields. Based on their material, they can be divided into plastic packaging bags, paper packaging bags, cloth packaging bags, etc. Different materials have different properties. Biodegradable packaging bags are environmentally friendly packaging products made from biodegradable materials, based on traditional packaging bags. They can degrade into harmless substances such as water and carbon dioxide in a short time in natural environments (such as soil and composting conditions) through microbial decomposition or the action of light and heat, fundamentally solving the white pollution problem caused by traditional, non-biodegradable plastic packaging.

[0003] However, existing biodegradable packaging bags have the following problems when used: Currently, biodegradable packaging bags are gradually replacing traditional plastic packaging due to their environmental protection characteristics. However, existing biodegradable packaging bags sacrifice structural strength in pursuit of degradability, making them prone to breakage under load and affecting their use. Furthermore, their sealing designs are often simple, making the bag openings prone to loosening due to external forces, resulting in a high risk of items falling out.

[0004] This utility model combines practicality and environmental protection. Through the synergy of multiple structures, it provides stable support for the bag body, achieves convenient and secure double sealing, ensures the load-bearing capacity and safety of the items during use, and ensures rapid degradation after use, reducing the environmental burden. Summary of the Invention

[0005] The present invention aims to solve the technical problems mentioned in the background art and provide a high-speed, easily degradable packaging bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed biodegradable packaging bag, comprising: a bag body, a support plate fixedly installed inside the bag body, a limiting clamp fixedly installed above the outer surface of the bag body, creases provided on the left and right sides and bottom of the bag body, the bag body being divided into inner and outer layers, the support plate being fixedly installed on the inner layer surface, and support blocks being fixedly installed at opposite corners of the bottom of the support plate, the bottom of the support blocks being fixedly connected to the corresponding corners of the inner layer of the bag body, and the limiting clamp consisting of limiting block one and limiting block two, which are respectively fixedly installed at the front and rear ends of the bag body.

[0007] A further preferred embodiment: a handle cavity is provided on the upper surface of both the front and rear ends of the bag body, and the first limiting block and the second limiting block are respectively fixedly installed above the handle cavity.

[0008] A further preferred embodiment: Each of the inner sides of the bag body has a through hole, and the through hole is on the same plane as the middle part of the limiting block one and the limiting block two.

[0009] A further preferred embodiment: Velcro is attached to two adjacent sides of the inner side of the bag, and the Velcro pieces are compatible with each other.

[0010] A further preferred embodiment: the outer layer of the bag is made of poly(butylene adipate / terephthalate) and calcium carbonate composite, and the inner layer of the bag is made of polyhydroxyalkanoate.

[0011] A further preferred embodiment: the support block is L-shaped, with its outer side fixedly connected to the inside of the bag body, and a second Velcro fastener is fixedly installed at its upper end, which is adapted to the bottom of the support plate.

[0012] A further preferred embodiment: a limiting ball is fixedly installed on the inner side of the first limiting block, and a limiting hole is opened on the inner side of the second limiting block, with the limiting ball embedded inside the limiting hole.

[0013] A further preferred embodiment: the through hole is larger than the limiting ball and the limiting hole. Beneficial effects

[0014] 1. By incorporating Velcro and a limiting clip, a double-sealing effect is achieved at the bag opening. Velcro allows for quick initial closure of the bag opening, offering convenient operation and a tight fit to prevent small items from falling out. The limiting clip provides secondary reinforcement through the mechanical engagement of the limiting ball and the limiting hole, preventing the bag opening from accidentally opening due to external pressure or handling, thus significantly improving sealing reliability. This double-sealing structure balances ease of use with robust sealing, facilitating quick sealing needs in daily life while ensuring the safety of items inside the bag during transportation or carrying. 2. By incorporating a support plate, support blocks, and Velcro straps, the L-shaped support blocks provide right-angle support to the bottom of the bag, preventing it from collapsing during loading. The support plate and support blocks are detachably connected via Velcro straps, ensuring vertical structural strength, dispersing the pressure of items on the side walls, and allowing the bag to be separated from the support plate when folded again. This design enhances the load-bearing stability of the packaging bag while maintaining its flexibility of use and does not affect its overall degradation performance. 3. In summary, this type of high-speed biodegradable packaging bag, through its structure including a bag body, support plate, support block, limiting clip, and Velcro, achieves a balance between strength and environmental friendliness through its multi-layered biodegradable material. The support plate and L-shaped support block work together, with Velcro providing stable yet flexible support. Velcro and the limiting clip form a double seal, facilitating quick operation while ensuring a secure seal. The various structures work together to improve the bag's load-bearing capacity, ease of use, and sealing reliability while maintaining its high-speed biodegradability, thus meeting both practical and environmental protection requirements.

[0020] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0021] Please see Figure 1-4In this embodiment of the utility model, a high-speed biodegradable packaging bag includes: a bag body 1, a support plate 2 fixedly installed inside the bag body 1, a limiting clamp 3 fixedly installed on the upper surface of the outer surface of the bag body 1, creases on the left and right sides and bottom of the bag body 1, the bag body 1 is divided into inner and outer layers, the support plate 2 is fixedly installed on the inner layer surface, and support blocks 201 are fixedly installed at the bottom diagonal corners of the support plate 2, the bottom of the support blocks 201 is fixedly connected to the corresponding corners of the inner layer of the bag body 1, the limiting clamp 3 is composed of limiting block one 301 and limiting block two 302, and is fixedly installed at the front and rear ends of the bag body 1 respectively, and a handle cavity 101 is opened on the upper surface of the front and rear ends of the bag body 1, the limiting block one 301 and the limiting block two 302 are fixedly installed above the handle cavity 101 respectively, and Velcro one 103 is pasted on the adjacent sides of the inner side of the bag body 1, the Velcro one 103 is adapted to each other, firstly using the creases on the left and right sides and bottom of the bag body 1, the bag body 1 is unfolded into a three-dimensional shape, at this time the support The plate 2 unfolds with the inner layer of the bag body 1. The support block 201 at the bottom provides support, allowing the bag body 1 to maintain a stable spatial structure, which facilitates the loading of items. When the items to be packaged are placed inside the bag body 1, the support plate 2 can provide some support for the items, preventing the bag body 1 from being excessively deformed due to the weight of the items. Through the matching Velcro 103 pasted on the adjacent sides of the inner side of the bag body 1, the Velcro 103 at the bag opening is glued together to achieve a preliminary seal at the bag opening, preventing items from falling out. The limiting clamp 3 on the outer surface of the bag body 1 consists of limiting block 301 and limiting block 302, which are fixed to the front and rear ends of the bag body 1, respectively. It can further limit the position of the bag opening, enhance the sealing effect, and at the same time, it can also prevent the bag opening from opening due to the squeezing of items to a certain extent. When it is necessary to lift the packaging bag, the handle cavity 101 opened on the upper surface of the front and rear ends of the bag body 1 can be used. The fingers can be inserted into the handle cavity 101 and, with the structure of the limiting clamp 3, the packaging bag can be lifted conveniently.

[0022] In this embodiment of the invention, a through hole 102 is provided on the upper inner side of the bag body 1. The through hole 102 is on the same plane as the middle part of the first limiting block 301 and the second limiting block 302. A limiting ball 303 is fixedly installed on the inner side of the first limiting block 301, and a limiting hole 304 is provided on the inner side of the second limiting block 302. The limiting ball 303 is embedded in the limiting hole 304. The through hole 102 is larger than the limiting ball 303 and the limiting hole 304. When sealing the bag opening, the front and rear ends of the bag body 1 are brought close to each other. This causes the limiting blocks 301 and 302 at the front and rear ends of the bag to approach each other. The limiting ball 303 on the limiting block 301 passes through the through hole 102 on the inner side of the bag body 1. Since the through hole 102 is larger than the ball and the limiting hole 304, it can pass through smoothly. The limiting ball 303 is embedded in the limiting hole 304 of the limiting block 302 to form a mechanical lock, which enhances the firmness of the bag opening seal. When a finger passes through the handle cavity 101, the locking structure of the limiting clamp 3 can disperse the pulling force when lifting and improve the load-bearing stability.

[0023] In this embodiment of the invention, the outer layer of the bag body 1 is made of polybutylene adipate / terephthalate (PBAT) and calcium carbonate composite, and the inner layer of the bag body 1 is made of polyhydroxyalkanoate (PHA). The outer layer is made of PBAT and calcium carbonate composite material. The flexibility and weather resistance of PBAT, combined with the enhanced hardness of calcium carbonate, make the bag less prone to damage due to friction or collision during unfolding and handling, while providing a stable adhesion base for the inner structure. The inner layer is made of PHA material, whose excellent biocompatibility and smooth surface can prevent the items inside the bag, especially fresh food, from sticking together. Moreover, PHA is not easily degraded when in contact with moisture and oil, ensuring structural stability during use. When the packaging bag is discarded, both PBAT and PHA can be rapidly decomposed under the action of microorganisms, and the materials do not contain the stubborn components of traditional plastics, and the degradation cycle is greatly shortened under suitable conditions.

[0024] In this embodiment of the invention, the support block 201 is L-shaped, with its outer side fixedly connected to the inside of the bag body 1, and a second Velcro fastener 202 fixedly installed at its upper end. The second Velcro fastener 202 is adapted to the bottom of the support plate 2. After the bag body 1 is unfolded using the creases, the L-shaped support block 201 naturally forms a right-angle support structure as the bottom of the bag body 1 unfolds. Its outer side is fixedly connected to the inside of the bag body 1, providing a stable right-angle support for the bottom of the bag body 1, avoiding the problem of easy collapse of traditional planar supports. By attaching the second Velcro fastener 202 at the upper end of the support block 201 to the bottom of the support plate 2, the support plate 2 and the support block 201 can be detachably fixed. The design ensures that the support plate 2 remains vertically supported during loading, and also allows the support block 201 to separate from the bottom of the support plate 2 when the bag body 1 is refolded. When sealing, the right-angle structure of the L-shaped support block 201 keeps the bottom of the bag body 1 stable, preventing the bag opening from shifting due to the pressure of the items. It also ensures that the limiting ball 303 can pass smoothly through the through hole 102 and cooperate with the limiting hole 304. When lifting, the combined structure of the support block 201 and the support plate 2 distributes the pulling force to the bottom and side walls of the bag body 1. Combined with the locking effect of the limiting clamp 3, it further improves the load-bearing stability of the packaging bag and reduces the risk of bag breakage.
