[0019] 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.

[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0021] When using traditional biodegradable food packaging bags, users may encounter situations where they need to store different types of food. Since different types of food cannot be stored together in one biodegradable food packaging bag, multiple biodegradable food packaging bags are needed to achieve the user's purpose. After a period of time, this situation may lead to a shortage of raw materials used to make biodegradable food packaging bags, thereby increasing their production costs.

[0022] In view of this, the present invention provides a biodegradable food packaging bag. This biodegradable food packaging bag, through the cooperation of a fixing seat, a raised strip, a sealing gasket, a groove strip, and a reinforcing unit, achieves the division of the internal space of the biodegradable food packaging bag, which can simultaneously hold different foods. This solves the problem that when using traditional biodegradable food packaging bags, users may encounter situations where they need to store different types of food in the bag, and different types of food cannot be stored together in one biodegradable food packaging bag. Multiple biodegradable food packaging bags are required to achieve the user's purpose. After a period of time, this situation may lead to a shortage of raw materials for making biodegradable food packaging bags, thereby increasing production costs.

[0023] Example 1, by Figure 1-4 As can be seen, the biodegradable food packaging bag in this case includes a bag body 1, and a partition component 2 is provided on the inner wall of the bag body 1. The partition component 2 includes: two fixing seats 21, which are fixedly connected to both sides of the inner wall of the bag body 1 respectively; a raised strip 22, which is fixedly connected to the side wall of one fixing seat 21; a sealing gasket 23, which is fixedly connected to the top and bottom of the raised strip 22 and its side wall is fixedly connected to the side wall of the fixing seat 21; a grooved strip 24, which is fixedly connected to the side wall of the other fixing seat 21; and a reinforcing unit 25, which is fixedly connected to one side of the outer wall of the bag body 1. The bag body 1 is divided into two spaces by the cooperation of the raised strip 22 and the grooved strip 24, and the two sealing gaskets 23 seal the joint between the raised strip 22 and the grooved strip 24.

[0024] In the specific implementation process, it is worth noting that the material of bag body 1 is biodegradable, selected according to actual needs, as long as it meets the requirements of the work. For example, it can be made of polylactic acid (PLA). Bag body 1 is transparent, allowing observation of the food inside when it is filled, facilitating user control over the quantity and quality of the food. The outer wall of bag body 1 is sealed, with a notch in the middle of the seals on both sides. Six fixing seats 21 are provided, arranged in pairs. The fixing seats 21 are made of biodegradable material, such as polybutylene terephthalate (PBAT). The fixing seats 21 are rectangular and fixed to both sides of the inner wall of bag body 1. Three protruding strips 22 are provided, located on the same side. The protruding strips 22 are made of biodegradable material, such as polybutylene terephthalate (PBAT). The cross-section of the protruding strips 22 is circular, allowing for micro-deformation. The convex strip 22 is designed to facilitate cooperation with the grooved strip 24. Three grooved strips 24 are provided on the same side. The grooved strips 24 are made of a biodegradable material, such as polybutylene terephthalate (PBAT). The grooved strips 24 can undergo slight deformation. Six sealing gaskets 23 are provided, arranged in pairs, at the top and bottom of the convex strip 22. The sealing gaskets 23 are also made of a biodegradable material, such as polybutylene terephthalate (PBAT). The sealing gaskets 23 can undergo slight deformation. When the convex strip 22 and the grooved strip 24 are used together, the sealing gaskets 23 can seal the space between the convex strip 22 and the grooved strip 24 through friction, thereby improving the sealing performance of the space after separation in the biodegradable food packaging bag. The various parts of the separating component 2 are fixed together by adhesives, the specific type of which can be selected according to actual needs, such as polyurethane adhesive for food packaging.

[0025] Furthermore, the outer wall of the bag body 1 is provided with a reinforcing unit 25, which includes: two bases 251, which are fixedly connected to both sides of the outer wall of the bag body 1; a connecting strap 252, which is fixedly connected to the surface of one base 251; an adhesive strip 253, which is fixedly connected to the side wall of the connecting strap 252 near the base 251; and a dustproof strip 254, which is fixedly connected to the side of the outer wall of the adhesive strip 253 away from the connecting strap 252. The other base 251 is connected to the two bases 251 through the cooperation of the connecting strap 252 and the adhesive strip 253.

[0026] In the specific implementation process, it is worth noting that there are two bases 251, located on both sides of the outer wall of the bag body 1, with a cuboid shape. The bases 251 are made of a biodegradable material, such as polybutylene succinate (PBS). There is one connecting strap 252, which is rectangular and also made of a biodegradable material, such as polybutylene succinate (PBS). There is one adhesive strip 253, which is made of a biodegradable material, such as protein adhesive, to prevent dust accumulation. There is one tape 254. The material of the anti-dust tape 254 is biodegradable, such as polybutylene succinate (PBS). When the bag body 1 is divided into two independent parts, the bottom of the upper part can be connected to the base 251 on both sides by the cooperation of the connecting tape 252 and the adhesive strip 253 to reinforce it, thereby improving the structural stability of the biodegradable food packaging bag. The various parts of the reinforcement unit 25 are fixed with adhesive. The specific type can be selected according to actual needs, such as polyurethane adhesive for food packaging.

[0027] Furthermore, two first connecting seats 11 are fixedly connected to the upper sides of both sides of the bag body 1, and a first carrying rope 12 is fixedly connected between the two first connecting seats 11 on one side. Two second connecting seats 13 are fixedly connected to the lower sides of both sides of the bag body 1, and a second carrying rope 14 is fixedly connected between the two second connecting seats 13 on one side.

[0028] In the specific implementation process, it is worth noting that there are four first connecting seats 11, with two on the same side forming a group, and they are circular in shape. The first connecting seats 11 are made of a biodegradable material, such as polylactic acid (PLA). There are two first carrying ropes 12, which are also made of a biodegradable material, such as polylactic acid (PLA). There are four second connecting seats 13, with two on the same side forming a group, and they are elliptical in shape. The second connecting seats 13 are also made of a biodegradable material, such as polylactic acid (PLA). 4. There are two handles. The second handle 14 is made of a biodegradable material, such as pineapple leaf fiber. The user can transfer the food inside the two separate parts of the bag 1 using the first handle 12 and the second handle 14, which improves the convenience of biodegradable food packaging bags. The first connecting seat 11 and the first handle 12 are fixed together with adhesive. The specific type can be selected according to actual needs. For example, it can be polyurethane adhesive for food packaging. The second connecting seat 13 and the second handle 14 are also fixed together with adhesive. The specific selection is the same as above.

[0029] Specifically, when storing multiple foods inside a biodegradable food packaging bag, the user first pinches the top two sides of the bag body 1 and pulls the bag body 1 open. Then, one type of food can be placed inside the bag body 1. This food will fall into the bottom space of the bag body 1 due to its own gravity. Once the user's specified quantity is reached, the biodegradable food packaging bag is placed on a table. The user places both hands on either side of the bottom set of raised strips 22 and grooved strips 24, pinching one end of the set of raised strips 22 and grooved strips 24 with one hand, and the other... Move one hand away from the pinched end of the protruding strip 22 and grooved strip 24 until the protruding strip 22 is fully inserted into the groove of the grooved strip 24, and the outer wall of the grooved strip 24 is fully inserted into the limiting groove formed by the sealing gasket 23 and the protruding strip 22. After this, squeeze the protruding strip 22 and grooved strip 24 again with both hands. Through the slight deformation of the protruding strip 22 and grooved strip 24, the protruding strip 22 and grooved strip 24 are fully adhered. Then, the user seals the set of protruding strips 22 and grooved strips 24 located in the middle of the bag body 1 in the above manner. At this time, the user will then place the other... Various types of food are placed in the space above bag 1. Once the quantity specified by the user is reached, the set of protruding strips 22 and grooved strips 24 on the top of bag 1 are sealed in the manner described above. The interior of bag 1 is divided into two parts, each containing a different type of food, thus improving the functionality of the biodegradable food packaging bag. Finally, the user lifts the biodegradable food packaging bag filled with food and transports it to a designated location. When it is necessary to open the biodegradable food packaging bag, the user reverses the above steps to remove the food from inside bag 1 one by one. When the biodegradable food packaging bag is extracted in two parts, the user can divide the bag body 1 into upper and lower parts horizontally according to the notches on both sides of the outer wall of the bag body 1. The user removes the dustproof strip 254 on the side wall of the adhesive strip 253 and pulls the connecting strip 252 to fix the adhesive strip 253 to the outer wall of the base 251 on the other side. This can reinforce a set of protruding strips 22 and groove strips 24 located in the middle of the bag body 1, preventing food in the space above the bag body 1 from falling to the outside of the biodegradable food packaging bag and causing loss, thereby improving the stability of the biodegradable food packaging bag structure.

[0030] Example 2, by Figure 1-5 It can be seen that a sealing seat 3 is fixedly connected to the upper part of the inner wall of the bag body 1, and a fixing groove 31 is provided on the side wall of the sealing seat 3;

[0031] In the specific implementation process, it is worth noting that there are two sealing seats 3, which are located on the upper sides of the inner wall of the bag body 1 and are rectangular in shape. The surface of the sealing seat 3 is provided with a fixing groove 31. The top view of the fixing groove 31 is trapezoidal, and the fixing grooves 31 on both sides are staggered and opposite. When the two sealing seats 3 are attached, they can improve the sealing performance of the bag body 1. The sealing seat 3 is made of a biodegradable material, such as polylactic acid (PLA), which improves the sealing performance of the biodegradable food packaging bag. The sealing seat 3 and the bag body 1 are fixed by an adhesive. The specific type can be selected according to actual needs, such as polyurethane adhesive for food packaging.

[0032] Furthermore, a reinforcing layer 4 is provided at the bottom of the inner wall of the bag body 1;

[0033] In the specific implementation process, it is worth noting that the material of the reinforcing layer 4 is a biodegradable material, such as polyhydroxyalkanoate (PHA). The reinforcing layer 4 is set at the bottom of the bag body 1, and the reinforcing layer 4 and the bag body 1 are fixed together by adhesive. The specific type can be selected according to actual needs. For example, it can be polyurethane adhesive for food packaging. This achieves the reinforcement of the bottom of the biodegradable food packaging bag and slows down the rate of heat loss at the bottom of the biodegradable food packaging bag.

[0034] Specifically, when the sealing seats 3 on both sides are attached, they improve the sealing performance of the biodegradable food packaging bag. At the same time, the reinforcing layer 4 reinforces the bottom of the biodegradable food packaging bag and keeps the food in the bottom space of the biodegradable food packaging bag warm, thus slowing down the rate of heat loss from the bottom of the biodegradable food packaging bag.
