[0003] In the prior art, a Chinese patent document with patent application number CN202021194134.9 describes a food packaging bag with antibacterial properties and discloses the antibacterial structure of the food packaging bag. However, the shortcoming is that the food packaging bag in the prior art has limited puncture resistance. Utility Model Content

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an environmentally friendly puncture-resistant food packaging bag, which can effectively solve the problem of limited puncture resistance of food packaging bags in the existing technology.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model provides an environmentally friendly puncture-resistant food packaging bag, including a bag body. The bag body has a layered structure, which consists of an outer shell, a connecting frame disposed inside the outer shell, a protective frame in contact with the connecting frame, and a puncture-resistant layer fixed to the bottom of the protective frame, arranged in order from the outside to the inside. The protective frame and the connecting frame are both hollow structures that bulge outwards, and an adhesive is coated and filled between the connecting frame and the protective frame. A fastening plate is disposed inside the protective frame, and the inside of the protective frame is a hollow structure that forms an inner groove, which is filled with adhesive.

[0009] Furthermore, the fastening plate is made of rigid plastic sheet material, and the fastening plate has a roll-up structure.

[0010] Furthermore, both the protective frame and the docking frame have a trapezoidal structure with a smooth top.

[0011] Furthermore, the adhesive between the docking frame and the protective frame is a buffer adhesive with a viscosity of 500cp to 2000cp.

[0012] Furthermore, a handle groove is provided at the top of the bag body, and a sealing part is provided at the bottom of the handle groove.

[0013] Furthermore, the puncture-resistant layer is a two-layer composite geomembrane.

[0014] Beneficial effects

[0015] The technical solution provided by this utility model has the following advantages compared with the known public technology:

[0016] This invention utilizes a layered structure consisting of an outer shell, a connecting frame, a protective frame, and a puncture-resistant layer. Specifically, the puncture-resistant layer is fixed to the outside by the protective frame and the connecting frame, with a buffer colloid structure filling the space between them. This buffer colloid has a viscosity of 500cp to 2000cp. When an external puncture occurs, the internal colloid structure weakens the puncture force, protecting the internal structure. The innermost puncture-resistant layer is a double-layer geomembrane structure. Utilizing the structural characteristics of this layer, it achieves seepage prevention, corrosion prevention, puncture resistance, and improved toughness, working in conjunction with the outer structure to enhance structural strength.

[0017] In this device, the interior of the protective frame is equipped with a fastening plate and an adhesive structure. The adhesive structure here can also be a colloid structure with a viscosity of 500cp to 2000cp, which fixes the fastening plate structure inside the protective frame. The rigid plastic plate structure can prevent the puncture structure from moving further inward. The roll-up fastening plate structure can enhance the structural strength. Together with the adhesive structure filling the outside of the fastening plate, it can provide multiple buffering functions. Attached Figure Description
