Description

Technical Field

[0001] This utility model relates to the field of food packaging bags, specifically a food packaging bag with good protective properties. Background Technology

[0002] With the booming development of the food industry, food packaging plays a crucial role in ensuring food quality, extending shelf life, and facilitating consumer storage and use. As one of the most common forms of food packaging, food packaging bags have continuously evolved in design and function to meet the increasingly diverse needs of the market and consumers. Currently, most food packaging bags widely used in the market employ self-sealing strips in their structural design to achieve secondary closure after opening. These self-sealing strips typically consist of two matching plastic strips that are pressed together to seal the bag. The advent of self-sealing strips greatly facilitates consumers in resealing packaging bags before the food is finished, maintaining food freshness to a certain extent and reducing the risk of spoilage due to contact with air.

[0003] However, existing food packaging bags that rely solely on self-sealing strips for secondary closure still have some shortcomings in practical use. Specifically, although self-sealing strips are convenient for adults, children with strong curiosity and a lack of awareness of danger can easily open food packaging bags with self-sealing strips when unsupervised, leading to accidental ingestion. This could result in children consuming food unsuitable for their age, causing physical discomfort. Therefore, a food packaging bag with better protection is proposed to address the above issues. Utility Model Content

[0004] To address the problem of inadequate protective effect of existing food packaging bags, this utility model proposes a food packaging bag with good protective properties.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a food packaging bag with good protection, including a packaging bag body and an adhesive part, the bottom of the packaging bag body is provided with a lower bag body, the top of the lower bag body is integrally formed with an upper bag body, and there is a bending part between the lower bag body and the upper bag body.

[0006] The lower bag body is provided with an adhesive part. After the upper bag body is folded along the bending part, the adhesive part is bonded to the outer surface of the upper bag body.

[0007] Preferably, the packaging bag body has an inner cavity, with a grooved strip fixed on one side wall near the bag opening and a protruding strip fixed on the other side wall.

[0008] Preferably, both the grooved strip and the raised strip are made of polyethylene material.

[0009] Preferably, when the opening of the packaging bag body is closed, the groove strip and the raised strip engage in a locking mechanism.

[0010] Preferably, the packaging bag body has arc-shaped openings on both sides to facilitate tearing open the packaging bag body.

[0011] Preferably, the adhesive part is non-adhesive.

[0012] The advantages of this utility model are:

[0013] 1. This utility model sets an adhesive part on the packaging bag body and uses the characteristics of self-adhesive to achieve a firm bond between the upper and lower ends of the bag after folding, thus constructing an effective secondary protection mechanism. Compared with traditional food packaging bags that rely solely on self-sealing strips, this significantly increases the difficulty for children to open the packaging bag. Children need to overcome both the physical obstruction of the folded bag body and the large peeling force generated by the self-adhesive adhesive, which significantly reduces the risk of children accidentally opening the bag and ingesting the contents, providing a more reliable guarantee for children's safety.

[0014] 2. This utility model achieves the folding and bonding of the upper and lower bag bodies through the adhesive part. Users can fold the bag body and fix it through the adhesive part, which greatly reduces the volume of the bag body. The smaller volume of the food packaging bag can achieve a higher loading density in the same transportation space, making transportation and carrying more convenient. In addition, the folded bag body, together with the use of the self-sealing strip, further enhances the sealing effect of the bag body. Attached Figure Description

[0021] 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 scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0023] This application discloses a food packaging bag with good protective properties. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A food packaging bag with good protective properties includes a packaging bag body 1 and an adhesive part 2. The bottom of the packaging bag body 1 is provided with a lower bag body 100, and the top of the lower bag body 100 is integrally formed with an upper bag body 101. A bending part 102 is provided between the lower bag body 100 and the upper bag body 101.

[0024] The lower bag body 100 is provided with an adhesive part 2. After the upper bag body 101 is folded along the bending part 102, the adhesive part 2 is bonded to the outer surface of the upper bag body 101. The adhesive part 2 is a self-adhesive. Using self-adhesive on the packaging bag body 1 can easily achieve functions such as sealing and label pasting, improve packaging efficiency, and can be reused.

[0025] Reference Figure 1 and Figure 3 The packaging bag body 1 has an inner cavity. A groove strip 4 is fixed on one side wall near the bag opening, and a raised strip 401 is fixed on the other side wall. Both the groove strip 4 and the raised strip 401 are made of polyethylene material. When the bag opening of the packaging bag body 1 is closed, the groove strip 4 and the raised strip 401 engage with each other. The engagement of the groove strip 4 and the raised strip 401 can repeatedly open and close the bag, and ensure the sealing of the bag after closing.

[0026] Reference Figure 1 The packaging bag body 1 has arc-shaped openings 3 on both sides to facilitate tearing open the packaging bag body 1. Through the arc-shaped openings 3, users can easily tear open the packaging bag body 1 and then take out the items inside the bag.

[0027] Working principle: When using the packaging bag body 1 at home, the user first squeezes both sides of the packaging bag body 1, causing the groove strip 4 and the raised strip 401 to snap together. Then, the upper bag body 101 is folded down along the bending part 102, so that the adhesive part 2 is bonded to the upper bag body 101. The properties of the self-adhesive are used to achieve a firm bond between the upper and lower ends of the bag after folding, thus building an effective secondary protection mechanism. This increases the difficulty for children to open the packaging bag, reduces the risk of children accidentally opening the bag and ingesting the contents, and provides a more reliable guarantee for children's safety.

[0028] In addition, the bag body is folded and fixed by the adhesive part 2, which greatly reduces the volume of the bag body. The smaller volume of the food packaging bag can achieve a higher loading density in the same transportation space, making transportation and carrying more convenient. Moreover, the folded bag body, together with the use of self-sealing strip, further enhances the sealing effect of the bag body.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
