With the upgrading of consumer demand, users have higher requirements for the portability, storage convenience and functional diversity of packaging bags, especially in scenarios that require frequent carrying or storage. The structural defects of traditional packaging bags gradually become prominent.
[0003] At present, the packaging bags on the market generally adopt a flat structure design, and the bag body is in a planar state after being unfolded. There is no effective folding and fixing mechanism. When the user needs to carry it, if he wants to reduce the occupied space of the packaging bag, he usually chooses to fold or fold it in half. However, the traditional packaging bag does not have a special folding and fixing structure, so that the folded bag body is difficult to maintain a stable state and is easy to return to the flat shape due to external force or the elasticity of the material itself. For example, a common food aluminum foil bag will naturally separate the upper and lower parts after being folded in half due to the lack of a fixing structure, which not only cannot achieve compact storage, but also may cause damage at the crease due to repeated folding. In addition, the hanging function of the traditional packaging bag is single, relying only on a single hanging hole at the bottom or top, and cannot form a stable hanging structure in the folded state.

DETAILED DESCRIPTION
[0025] The utility model will be further described in combination with the specific embodiments and the drawings, and reference is made to Figs. 1-3 :
[0026] Embodiment 1:
[0027] The embodiment provides a portable packaging bag, which comprises:
[0028] The bag body 1 has a top sealing part 10, a top sealing opening 11 located below the top sealing part 10, and a bottom hanging hole 12 located below the bag body 1;
[0029] The middle folding line 2 is horizontally arranged at the center of the bag body 1 and is used for folding the bag body 1;
[0030] The folding combination module 3 has a combination structure 30 symmetrically arranged on the upper and lower sides of the folding line, and the combination structure 30 is used for fixing the folded state of the bag body 1;
[0031] The top cutting line 4 is arranged on the top sealing part 10 and forms a tongue 5 used for assisting the opening of the top sealing opening 11 after being torn, the top hanging hole 6 is arranged on the tongue 5, and the top hanging hole 6 is aligned with the bottom hanging hole 12 in the folded state of the bag body 1.
[0032] The bag body 1 is the main part of the entire portable packaging bag, used to contain articles, and plays a role in protecting and carrying articles. The bag body 1 is usually rectangular, oval or other shapes, and is the basic part of the entire packaging bag, and other components are arranged on the bag body 1.
[0033] The top sealing part 10 is used to seal the top of the bag body 1 to prevent leakage of the contents of the bag, and to ensure the sealing and safety of the contents. The top sealing part 10 matches the shape of the top of the bag body 1, and is usually a sealing area formed by special treatment on the top of the bag body 1, which can be connected to the bag body 1 by heat pressing or adhesion.
[0034] The top sealing opening 11 is a channel for putting and taking articles into and out of the bag body 1, and is an opening area below the top sealing part 10 of the bag body 1, which is in a sealed state when not opened. The top sealing opening 11 is usually a long strip-shaped concave-convex fitting structure, which is adapted to the width of the bag body 1. The top sealing opening 11 can also be connected to the bag body 1 by heat pressing or adhesion.
[0035] The bottom hanging hole 12 is used for hanging the packaging bag for display or storage. The bottom hanging hole 12 is a hole formed at the bottom of the bag body 1, and its shape is generally circular or elliptical, or other shapes that are convenient for hanging.
[0036] The middle folding line 2 provides a folding reference line for the bag body 1, facilitating folding of the bag body 1, reducing the volume of the packaging bag, and facilitating carrying and storage. The middle folding line 2 is a crease or weakened area arranged transversely along the center of the bag body 1, making the bag body 1 more easily foldable at this point. The middle folding line 2 is integral with the bag body 1 and can be made by indentation or other special treatment.
[0037] The folding joint module 3 is used to fix the folded state of the bag body 1, so that the bag body 1 can remain stable after folding and will not easily unfold, ensuring that the folded packaging bag maintains a compact form during carrying and storage, further improving portability.
[0038] The top cutting line 4 is used to guide the user to tear the top sealing part 10 to form a tongue 5, facilitating the opening of the top sealing opening 11. The top cutting line 4 is a weakened line arranged on the top sealing part 10, usually formed by cutting or indentation. The shape of the top cutting line 4 is generally a straight line or a curve, designed according to the shape of the tongue 5.
[0039] The tongue 5 is used to assist in the opening of the top sealing opening 11, facilitating user operation. By pulling the tongue 5, the top sealing opening 11 can be opened more easily, avoiding damage caused by directly pulling the bag body 1. The tongue 5 is formed by tearing the top cutting line 4, and its shape is conducive to concentrating the pulling force, making it easier to open the sealing opening. The tongue 5 is connected to the top sealing opening 11 by the residual top sealing part 10.
[0040] The top hanging hole 6 is aligned with the bottom hanging hole 12 in the folded state of the bag body 1, forming a hanging channel, which facilitates the hanging of the folded packaging bag, thereby further improving the hanging convenience of the packaging bag in the folded state and increasing the use scenarios. The top hanging hole 6 is a hole formed on the tongue 5, and its shape matches that of the bottom hanging hole 12.
[0041] When it is necessary to carry or store the packaging bag, the user can fold the bag body 1 along the middle folding line 2, and at this time, the coupling structures 30 of the folding coupling module 3 cooperate with each other to fix the folded state of the bag body 1, so that the packaging bag remains in a compact form and the volume is reduced. In this state, the top hanging hole 6 on the tongue 5 is aligned with the bottom hanging hole 12 at the bottom of the bag body 1, and the user can pass the two holes through a hanging device such as a hook to hang the folded packaging bag.
[0042] When it is necessary to take out the items in the bag, the user tears the top sealing part 10 along the top cutting line 4 to form the tongue 5. Then the tongue 5 is pulled, and since the tongue 5 is connected to the top sealing opening 11 through the remaining top sealing part 10, pulling the tongue 5 can drive the top sealing opening 11 to open, thereby conveniently taking out the items. After use, the items are placed in the bag body 1, and the top sealing opening 11 can be naturally closed or closed with the aid of appropriate pressing or the like.
[0043] Embodiment 2:
[0044] The present embodiment provides a portable packaging bag, which, in addition to the technical solutions of the above embodiments, has the following technical features.
[0045] The coupling structure 30 adopts a Velcro assembly 300, which includes hook surfaces 3001 and loop surfaces 3002 symmetrically arranged on the upper and lower sides of the folding line, and fixes the folded state of the bag body 1 through adhesive action.
[0046] The Velcro assembly 300, as a specific implementation form of the coupling structure 30, uses the adhesive action between the hook surfaces 3001 and the loop surfaces 3002 to fix the folded state of the bag body 1, providing a convenient and reusable fixing method. The user can easily fold and fix the bag body 1, and can also quickly unfasten it when needed, which is simple and convenient to operate. The Velcro assembly 300 is composed of two parts, the hook surfaces 3001 and the loop surfaces 3002. The hook surfaces 3001 are covered with tiny hooks, and the loop surfaces 3002 are fine fibers. The hook surfaces 3001 and the loop surfaces 3002 are respectively arranged on the upper and lower sides of the folding line, and when the bag body 1 is folded, the hook surfaces 3001 and the loop surfaces 3002 are opposite and can adhere to each other. The hook surfaces 3001 and the loop surfaces 3002 can be fixed on the bag body 1 by adhesion or hot pressing, so as to ensure that they will not easily fall off during use.
[0047] When it is needed to fold the bag body 1, the user folds the bag body 1 along the middle folding line 2, so that the hook surface 3001 and the loop surface 3002 of the Velcro assembly 300 on the upper and lower sides of the folding line are close to each other. Since the hooks of the hook surface 3001 and the fibers of the loop surface 3002 have the feature of mutual entanglement, when they are in contact, the hooks will automatically grab the fibers, thereby realizing the adhesion of the Velcro and fixing the folded state of the bag body 1.
[0048] When it is needed to unfold the bag body 1, the user only needs to separate the hook surface 3001 and the loop surface 3002 by force, so that the hooks are separated from the fibers, thereby releasing the fixed state and unfolding the bag body 1. The adhesion and separation process can be repeated, which facilitates the user to fold and unfold the bag body 1 according to actual needs.
[0049] Embodiment 3:
[0050] The portable packaging bag provided in the embodiment further has the following technical features in addition to the technical solutions of the above embodiments.

[0052] The magnetic attraction assembly 301 realizes the fixation of the folded state of the bag body 1 by using the magnetic force between the magnet and the magnetic guide material, and provides a stable and reusable fixation mode. The user can easily fold and fix the bag body 1, and can also easily unfold it. The magnetic attraction assembly 301 is composed of two parts, the magnetic strips 3010 and the magnetic guide sheets 3011, which cooperate with each other to generate an adsorption force. The magnetic strips 3010 and the magnetic guide sheets 3011 are respectively located on the upper and lower sides of the folding line, and can be accurately positioned and adsorbed when the bag body 1 is folded. The magnetic strips 3010 and the magnetic guide sheets 3011 can be connected to the bag body 1 by pasting or hot pressing, so as to ensure that the bag body 1 becomes an integral whole.
