[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. Examples of these preferred implementation manners are illustrated in the accompanying drawings. The implementation manners of the present utility model shown in the drawings and described according to the drawings are merely exemplary, and the present utility model is not limited to these implementation manners.

[0024] Here, it should also be noted that, in order to avoid obscuring the present utility model due to unnecessary details, only the structures and / or processing steps closely related to the solution according to the present utility model are shown in the drawings, while other details of little relevance are omitted.

[0025] Combined with Figure 1 and Figure 2 As shown, an embodiment of the present utility model provides an environmentally friendly food packaging bag, which includes a bag body 1, a concave-convex zipper seal 2, a side seal edge 3, and a secondary bag 4. Among them, a tearing strip 11 is provided at the top of the bag body 1, and the tearing strip 11 is used to tear off from the bag body 1 to form a tear opening at the top of the bag body 1. The concave-convex zipper seal 2 is arranged below the tearing strip 11 to close the tear opening of the bag body 1 to form an internal storage space of the bag body 1. The side edge of the secondary bag 4 is connected to the side seal edge 3. Disposable tableware or seasoning packets are stored inside the secondary bag 4. The secondary bag 4 is attached to the surface of the bag body 1 through multiple layers of folding, and its top edge is bonded to the tearing strip 11 to close and seal the opening of the secondary bag 4, so that the opening of the secondary bag 4 can be opened as the tearing strip 11 is torn off.

[0026] The usage principle of the above-mentioned food environmental protection packaging bag is as follows: The user can directly tear off the tear strip 11 in the same way as a conventional food packaging bag, so that the top of the bag body is torn open to form an opening. At the same time, since the top edge of the secondary bag 4 is adhesively connected to the tear strip 11 and seals the opening of the secondary bag 4, as the tear strip 11 is torn off, the connection between the top edge of the secondary bag 4 and the tear strip 11 will also be torn off, and the structure fixing the folded shape of the secondary bag 4 is damaged, so that the top opening of the secondary bag 4 is opened and can be unfolded. The user can conveniently take out the disposable tableware or seasoning packet in the secondary bag 4, and then open the concave-convex zipper seal 2 to take out the food contained in the bag body 1. In the existing packaging bags, since the disposable tableware or seasoning packet is in direct contact with the food, when the user reaches into the food packaging bag to take it out, the hand will inevitably be contaminated by the food first before opening the small independent package. However, the above-mentioned food environmental protection packaging bag not only avoids the outer surface of the disposable tableware or seasoning packet from being contaminated by the food inside the bag body 1 and avoids soiling the user's hands, but also ensures the sealed cleanliness of the disposable tableware or seasoning packet. The usage method is the same as that of the conventional tear-open packaging and sealing structure, without repeated steps, is convenient to use, has a simple structure and is easy to implement, and has a low additional cost, suitable for large-scale mass production lines. In addition, residual garbage such as food shells, torn tear strips 11, small independent packaging bags of disposable tableware and seasoning packets can be all put into the secondary bag 4, and then disposed of together with the food environmental protection packaging bag later, avoiding the situation where the residual garbage has nowhere to be placed and preventing the phenomenon of environmental pollution caused by the user's random disposal.

[0027] Specifically, in this embodiment, the top edge of the secondary bag 4 is flush with the edge of the tear line of the tear strip 11, and an easy tear line is formed at the connection. The connection and the tear line of the tear strip 11 are on the same straight line of the easy tear line, so that the secondary bag 4 can be easily torn synchronously with the connection to the tear strip 11, and at the same time, it can exactly maintain the folded fixation of the secondary bag 4 and the closure of the internal space before tearing.

[0028] Exemplarily, the secondary bag 4 includes three side faces 41 connected end to end, and when unfolded, it forms a triangular prism structure. The edges of the secondary bag 4 are connected to the side seal 3. The above is only an example of the structural design of the secondary bag 4. Actually, parameters such as the shape, size and number of folding layers of the secondary bag 4 after unfolding can be designed according to requirements.

[0029] To facilitate the alignment of each layer of the folded secondary bag 4 and maintain a consistent rule, folding folds 42 are provided on the midlines of the side faces 41 of the secondary bag 4.

[0030] Furthermore, the folding folds 42 are marked easy tear crease lines. Thus, according to requirements, the secondary bag 4 can be torn along the folding folds 42, making it more convenient to take out the contents in the secondary bag 4 and improving the user experience.

[0031] Generally, there is a need to hang the food environmental protection packaging bags during transportation to sales. Therefore, without exception, in the above-mentioned food environmental protection packaging bags, hanging holes 110 are stamped on the tearing strip 11.

[0032] Similarly, for the convenience of the user to tear easily, tear notches 111 are provided at both ends of the tearing strip 11. Corresponding to the edge of the tearing line of the tearing strip 11, the user can tear the tearing strip 11 from both sides at will, which can also improve the user experience.

[0033] In order to prevent the user from tearing the folding wrinkles 42 too hard, making the opening too large and damaging the storage space of the secondary bag 4, and to guide the user to properly open the secondary bag 4, the folding wrinkles 42 extend from the top edge of the secondary bag 4 to the middle of the secondary bag 4, and the secondary bag 4 is provided with a limiting edge 43 at the end corresponding to the folding wrinkles 42.
