[0002] In the field of food packaging, packaging bags not only play a role in protecting food, but also play an important role in ensuring the authenticity and tamper-proofing of products. In recent years, with the continuous improvement of consumers' requirements for food safety and product authenticity, especially in the field of green food and high-value products, preventing packaging tampering has become a common concern of manufacturers and consumers. Traditional anti-counterfeiting marks and anti-tampering mechanisms often show shortcomings and loopholes when facing infringements by some unscrupulous merchants. Therefore, it is particularly important to develop a food packaging bag that can effectively prevent tampering and is easy to identify and operate.

[0003] Among the existing technologies, the food packaging bags commonly seen on the market currently mainly rely on technologies such as anti-counterfeiting labels and anti-counterfeiting codes for anti-counterfeiting and anti-tampering, but these methods still have certain risks of being cracked and counterfeited. In particular, the markers on the packaging bags are easily tampered or replaced by unscrupulous merchants through technical means, and it is difficult for consumers to intuitively identify whether the product has been tampered with. In addition, the existing anti-tampering design is usually complicated in operation and identification, which increases production costs and the difficulty of use for consumers.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0023] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a hot-melt printed food packaging bag and a food packaging bag, comprising: a bag body 11, a convex plate 12 is arranged on the inner side of the bag body 11, the inner side of the bag body 11 is fixedly connected to one side of the convex plate 12, a concave plate 13 is arranged on the inner side of the convex plate 12, the inner side of the convex plate 12 is fitted with one end of the concave plate 13, plastic ropes 14 are arranged inside the concave plate 13 and the convex plate 12, the interiors of the concave plate 13 and the convex plate 12 are penetrated and fixedly connected with one end of the plastic rope 14, one side of the concave plate 13 is fixedly connected to the inner side of the bag body 11, a logo 112 is arranged on the inner side of the bag body 11, the inner side of the bag body 11 is fixedly connected to one side of the logo 112, a sealing strip 15 is arranged on the inner side of the bag body 11, and the inner side of the bag body 11 is fixedly connected to one side of the sealing strip 15.

[0024] In this embodiment, in order to prevent unscrupulous merchants from changing the mark 112 of the packaging bag when the packaging bag is in use, the mark 112 is designed on the inner wall of the bag body 11 at the bag mouth, and a convex plate 12 and a concave plate 13 are designed above the mark 112, with a plastic rope 14 between the two. If an unscrupulous merchant tries to separate the convex plate 12 and the concave plate 13, the plastic rope 14 connecting them will break. This plastic rope 14 is designed to be irreversible once broken, thereby forming an irreversible anti-tampering mechanism. Once the plastic rope 14 breaks, the separation of the convex plate 12 and the concave plate 13 will be clearly exposed, and the integrity of the mark 112 will be destroyed. This state is clearly visible and easy to identify tampering. Therefore, through this design, the packaging bag can not only ensure the safety of the mark 112 when in use, but also provide a simple and effective anti-tampering means through the irreversibility of the physical structure, and can also effectively improve the safety and credibility of the product, and fully protect the rights and interests of consumers. At the same time, since the design and manufacturing costs of the plastic rope 14, the convex plate 12 and the concave plate 13 are relatively low, the production cost of the packaging bag will not be significantly increased, and the packaging bag is suitable for large-scale application. Example

[0025] like Figure 1 - Figure 3 As shown, a plastic grid 16 is provided inside the bag body 11, and the inside of the bag body 11 is fixedly connected to one side of the plastic grid 16, and a moisture-proof layer 17 is provided on the other side of the plastic grid 16, and the other side of the plastic grid 16 is fixedly connected to one side of the moisture-proof layer 17, and an anti-oxidation layer 18 is provided on the other side of the moisture-proof layer 17, and one side of the anti-oxidation layer 18 is fixedly connected to the other side of the moisture-proof layer 17, and an anti-bacterial layer 19 is provided on the other side of the anti-oxidation layer 18, and the other side of the anti-oxidation layer 18 is fixedly connected to one side of the anti-bacterial layer 19, and a buffer layer 110 is provided on the other side of the anti-bacterial layer 19, and the other side of the anti-bacterial layer 19 is fixedly connected to one side of the buffer layer 110, and an evaporation layer 111 is provided on the other side of the buffer layer 110, and the other side of the buffer layer 110 is fixedly connected to one side of the evaporation layer 111, and the other side of the evaporation layer 111 is fixedly connected to the inside of the bag body 11.

[0026] In this embodiment, multiple material layers are designed in the bag body 11, including a plastic grid 16, a moisture-proof layer 17, an anti-oxidation layer 18, an antibacterial layer 19, a buffer layer 110 and an evaporation layer 111. The plastic grid 16 layer is the outermost layer, which provides basic structural support and durability and enhances the overall strength of the bag body 11. The plastic grid 16 layer is immediately adjacent to the plastic grid 16 layer, and a waterproof material is used to prevent external moisture from entering the bag and keep the food dry. The moisture-proof layer 17 is made of a material that blocks oxygen to prevent food oxidation, extend the shelf life, prevent bacteria and microorganisms from multiplying in the bag, and ensure food hygiene. The antibacterial layer 19 and the buffer layer 110 prevent external impact and extrusion from damaging the food and protect the integrity of the food in the package. The evaporation layer 111 allows excess moisture in the bag to evaporate, maintains a suitable internal environment, and prevents the food from getting damp and deteriorating.

[0027] Working principle:

[0028] like Figure 1 As shown in the figure, the logo 112 is designed on the inner wall of the bag body 11, located at the bag mouth, and a convex plate 12 and a concave plate 13 are designed above the logo 112, with a plastic rope 14 between the two. If an unscrupulous merchant tries to separate the convex plate 12 and the concave plate 13, the plastic rope 14 connecting them will break. The plastic rope 14 is designed to be irreversible once broken, thus forming an irreversible anti-tampering mechanism. Once the plastic rope 14 breaks, the separation of the convex plate 12 and the concave plate 13 will be clearly exposed, and the integrity of the logo 112 will be destroyed. This state is clearly visible and easy to identify tampering behavior;

[0029] By designing multiple material layers in the bag body 11, the packaging bag can provide comprehensive protection functions, including moisture-proof, anti-oxidation, antibacterial, buffering and evaporation, etc., effectively extending the shelf life of food and improving product safety. In addition, the multiple material layers work synergistically to improve the overall strength and durability of the packaging bag, and it can withstand the test of various external environments.
