Description

Technical Field

[0001] The utility model relates to the field of packaging bags, in particular to a high-strength plastic packaging bag. Background Art

[0002] A plastic packaging bag is a packaging bag made of plastic as raw material and is used for various articles in production and life. It is widely used in daily life and industrial production. Commonly used plastic packaging bags are mostly made of polyethylene film. This film is non-toxic, so it can be used to hold food. Plastic packaging bags can be classified into OPP, CPP, PP, PE, PVA, EVA, composite bags, co-extruded bags, etc. with respect to the material. With the progress of technology and the development of society, the problem of environmental pollution has attracted more and more attention from people. Therefore, degradable materials are applied to packaging bags to reduce plastic pollution at the source.

[0003] According to the disclosed patent 202222286972.4, a high-strength and easily degradable plastic packaging bag includes a packaging bag body and an integrated component. A suspension piece is fixedly connected to the center of the top of the packaging bag body. The packaging bag body includes a first mounting piece and a second mounting piece. A reinforcing fiber is installed through the opposite sides of the first mounting piece and the second mounting piece. The integrated component includes an anti-aging outer layer, a tensile layer, a soft connection layer and a tough inner layer. A through hole is provided at the connection between the packaging bag body and the suspension piece. The reinforcing fiber is bent. In the process of implementing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. By using the first mounting piece, the reinforcing fiber, the second mounting piece, the anti-aging outer layer, the tensile layer, the soft connection layer and the tough inner layer in cooperation, the problems of poor tensile strength and toughness of the plastic packaging bag are solved. During use, no additional reinforcing structure is added between the lifting belt and the bag body of the traditional high-strength plastic packaging bag. The lifting belt is prone to breakage due to the excessive weight of the contents in the packaging bag during use; moreover, the whole packaging bag is prone to damage during use. Therefore, a new technical solution needs to be designed to solve this problem. Content of the Utility Model

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a high-strength plastic packaging bag to solve the technical problems that no additional reinforcing structure is added between the lifting belt and the bag body of the current high-strength plastic packaging bag, the lifting belt is prone to breakage due to the excessive weight of the contents in the packaging bag during use; and the whole packaging bag is prone to damage during use.

[0005] To achieve the object of the present utility model, the technical solution adopted by the present utility model is as follows: Design a high-strength plastic packaging bag, including a bag body. At the edges of both ends of the bag body, carrying straps are installed. Reinforcing straps are installed on the surfaces of the carrying straps and the bag body. First reinforcing straps are installed on both sides of the bag body, and a second reinforcing strap is installed at the bottom of the bag body.

[0006] Preferably, the carrying straps are integrally formed at the edges of both ends of the bag body.

[0007] Preferably, the reinforcing straps surround the outside of the carrying straps and the bag body and are integrally formed with the outside of the carrying straps and the bag body.

[0008] Preferably, one end of the first reinforcing strap is fixedly connected to the junction of the carrying strap and the reinforcing strap, and the other end of the first reinforcing strap is fixedly connected to the junction of the reinforcing strap and the bottom of the bag body.

[0009] Preferably, both ends of the second reinforcing strap are fixedly connected between the two carrying straps and are fixedly connected to the bottom of the bag body.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] By surrounding the reinforcing straps around the outside of the carrying straps and the bag body and integrally forming them with the outside of the carrying straps and the bag body, the present utility model enhances the firmness of the carrying straps during use and avoids the phenomenon that the carrying straps are pulled and broken when the things in the packaging bag are too heavy.

[0012] Moreover, by adding the first reinforcing strap and the second reinforcing strap to the outside and the bottom of the bag body, the strength of the bag body during use is improved, and the probability of damage to the whole packaging bag during use is reduced, so that the packaging bag can be reused.

[0017] The present utility model will be further described below with reference to the drawings and embodiments:

[0018] Embodiment 1: A high-strength plastic packaging bag, seeFigures 1 to 3 , including a bag body 1. At the edges of both ends of the bag body 1, carrying straps 11 are installed. The carrying straps 11 are integrally formed at the edges of both ends of the bag body 1. A reinforcing strap 12 is installed on the surfaces of the carrying straps 11 and the bag body 1. The reinforcing strap 12 surrounds the outside of the carrying straps 11 and the bag body 1 and is integrally formed with the outside of the carrying straps 11 and the bag body 1. By surrounding the outside of the carrying straps 11 and the bag body 1 with the reinforcing strap 12 and integrally forming it with the outside of the carrying straps 11 and the bag body 1, the firmness of the carrying straps 11 during use is enhanced, and the phenomenon that the carrying straps 11 are pulled and broken when the things in the packaging bag are too heavy is avoided;
