Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of liquid packaging bags, in particular to a high-strength liquid packaging bag. Background Art
[0002] Packaging bags refer to bags used to package various items, making it easy to transport and store goods during production and circulation. They are widely used in daily life and industrial production. Actual figures show that most plastic bags are usually transported to landfills like general garbage. Liquid packaging bags are common packaging bags, which are specially used to package liquids and are widely used in food, beverages, cosmetics, medicine and other fields. Liquid packaging bags are an important part of liquid packaging. They can not only protect the quality and safety of liquid products, but also improve the added value and market competitiveness of products.
[0003] Common liquid packaging bags are usually composed of a bag body, an inlet and outlet, and an outer coating. When in use, the liquid is first injected or exported through the inlet and outlet, and a cap is threadedly connected to the top of the inlet and outlet, and the outer coating is coated on the surface of the bag body. This is a common liquid packaging bag structure and usage method. The packaging structure of traditional liquid packaging bags is not set reasonably, and there are problems such as low strength, single structure, and inconvenient use. It is easy to fall and leak during transportation or handling, which poses certain safety hazards. For example, patent announcement number CN211811033U is a high-strength liquid packaging bag. By using aluminum foil, water-filtering plastic film, and high-density polyethylene as materials for the bag body, the toughness and load-bearing capacity of the bag body can be improved. However, in this way, since the load-bearing capacity and mechanical strength of the liquid packaging bag are improved only by using a variety of different materials, the overall anti-fall and anti-leakage effects of the liquid packaging bag are limited. For this reason, a high-strength liquid packaging bag is proposed. Utility Model Content
