Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to a packaging bag. Background Technology

[0002] In today's society, packaging bags, as a type of bag used to package various items, have extremely wide applications and play an indispensable role in daily life scenarios such as shopping and storing goods. Among them, paper packaging bags, with their environmentally friendly and biodegradable characteristics, are favored in packaging fields with high environmental protection requirements, such as food and gifts.

[0003] Currently, after the flowers are tied up, florists will trim, package and decorate the bouquets. Traditionally, paper bags are used for packaging. However, since flowers usually retain moisture, the paper bags are easily soaked in humid environments, leading to damage and deformation, which affects the appearance. Therefore, this needs to be improved. Utility Model Content

[0004] In order to improve the strength and scope of use of packaging paper bags, this application provides a packaging bag.

[0005] The packaging bag provided in this application adopts the following technical solution:

[0006] A packaging bag includes a bag body with an opening. The bag body includes a bottom plate, a main plate, and side plates. Two main plates and two side plates are provided. The two main plates are arranged opposite each other, and the two side plates are arranged opposite each other. The two main plates and two side plates are connected to the edge of the bottom plate and enclose a receiving cavity. A waterproof layer is provided on the inner wall of the bag body.

[0007] By adopting the above technical solution, items such as flowers can be placed inside the containment cavity. The design of the waterproof layer can improve the waterproof ability of the entire packaging bag, thereby preventing water from penetrating the bag body, increasing the strength of the packaging paper bag, and enabling the packaging bag to be reused.

[0008] Preferably, the bag body is in the shape of a frustum.

[0009] By adopting the above technical solution, the shape of the frustum is smaller at the top and larger at the bottom. This structure allows the packaging bag to hold more items at the bottom. At the same time, its unique shape can better adapt to packaging irregularly shaped items, reducing internal gaps and thus improving space utilization. Furthermore, due to the shape of the frustum, the center of gravity of the packaging bag is relatively low. Objects with a low center of gravity are less likely to sway or tip over when subjected to external forces, further improving the stability of the packaging bag.

[0010] Preferably, the main board includes a first plate, a connecting plate, a second plate, and an inner buckle plate. The connecting plate is used to connect the first plate and the second plate. The first plate and the second plate are respectively connected to the two side plates. The first plate is folded to form a first folded portion and a second folded portion. The second plate is folded to form a third folded portion and a fourth folded portion. The first folded portion, the third folded portion, the second folded portion, and the fourth folded portion are stacked together in sequence. The fourth folded portion is attached to the connecting plate. The inner buckle plate is disposed on the connecting plate and is used to press the first folded portion onto the connecting plate.

[0011] By adopting the above technical solution, the first fold, the third fold, the second fold, and the fourth fold are stacked together, which can improve the strength of the entire main board and extend the service life of the bag.

[0012] Preferably, both main boards are connected to a carrying strap, and the carrying strap is connected to the main board near the opening of the bag.

[0013] By adopting the above technical solution, the carrying strap provides a convenient gripping point. When people need to carry a bag containing items, they can easily lift the bag by simply holding the carrying strap, making the carrying process more convenient.

[0014] Preferably, the inner buckle plate has a handle hole, which is an elliptical hole or a round hole, and the handle hole is used for the handle rope to pass through.

[0015] By adopting the above technical solution, the end of the carrying rope is connected to the carrying hole, thus realizing the installation of the carrying rope.

[0016] Preferably, the base plate has a honeycomb core structure.

[0017] By adopting the above technical solution, the hexagonal structure of the honeycomb core gives it high compressive strength in all directions within the plane, allowing the base plate to withstand greater pressure without easily deforming. Under the same strength requirements, the honeycomb core base plate is lighter and has lower material costs, thus reducing production costs.

[0018] Preferably, a transparent label frame is provided on the outer wall of the motherboard, and the transparent label frame is used to place label paper.

[0019] By adopting the above technical solution, the label paper can be clipped into a transparent label frame. The label paper can be used to indicate product names and other information, helping consumers quickly understand the basic information of the product and facilitating their purchase. At the same time, the label paper can also be used to showcase the merchant's brand, enhancing brand awareness.

[0020] Preferably, the bag body is formed by folding a one-piece cardboard structure.

[0021] By adopting the above technical solutions, foldable packaging bags can be easily folded into flat or other small shapes when not in use, taking up very little space. At the same time, foldable packaging bags can be reused multiple times, reducing reliance on single-use plastic bags. Single-use plastic bags are difficult to degrade and cause serious environmental pollution, while the use of foldable packaging bags helps reduce white pollution and protect the ecological environment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] (1) By setting a waterproof layer on the inner wall of the bag, the design of the waterproof layer can improve the waterproof ability of the entire packaging bag, thereby preventing water from penetrating the bag, improving the strength of the packaging paper bag, enabling the packaging bag to be reused, extending the service life of the packaging bag and expanding the scope of use of the packaging bag.

[0024] (2) By setting a handle, the handle provides a convenient gripping part. When people need to carry a bag containing items, they can easily lift the bag by simply holding the handle, thus improving the convenience of the bag.

[0025] (3) By setting a transparent label frame, the label frame can be used to place the label paper, and the label paper can display relevant information about the product or merchant. Attached Figure Description
