Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging bags, in particular to a plastic packaging bag with a bag-tying function. Background Art

[0002] Plastic packaging bags are made of plastic as raw materials and are used for packaging various articles in production and life. They are widely used in daily life and industrial production. However, this temporary convenience brings long-term harm. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic and can be used to contain food. There is also a kind of film made of polyvinyl chloride. Polyvinyl chloride itself is also non-toxic, but the additives added according to the use of the film are often harmful substances to the human body and have certain toxicity. Therefore, this kind of film and the plastic bags made of this film are not suitable for containing food. Plastic woven bags are mainly composed of polypropylene bags and polyethylene bags according to the main materials, and are divided into bottom-sewn bags and side-bottom-sewn bags according to the sewing method. They are a kind of packaging material widely used in fertilizers, chemical products and other items. Its main production process is to use plastic raw materials to extrude into films, cut, and unidirectionally stretch into flat filaments, and then obtain products through warp and weft weaving, generally called woven bags. The characteristics of plastic bags are: light weight, high strength, corrosion resistance, etc. After adding a plastic film lining, moisture-proof and wet-proof can be achieved; the load capacity of light bags is below 2.5 kg, the load capacity of medium bags is 25-50 kg, and the load capacity of heavy bags is 50-100 kg. Plastic packaging bags are consumables in daily life, and China consumes a large amount of plastic shopping bags every year. While providing convenience for consumers, due to reasons such as excessive use and improper recycling and treatment, plastic packaging bags also cause serious waste of energy resources and environmental pollution.

[0003] At present, the types of plastic packaging bags are numerous in terms of variety and color. However, littering plastic bags will cause great pollution to the environment. Most of the plastic bags on the market are vest-shaped. This kind of plastic bag is cheap in cost, but it is easy to tie a dead knot when tying the bag mouth, making it difficult to open and even unable to be used, so it is discarded, bringing pollution to the environment.
