Description

Technical Field

[0001] The utility model relates to the technical field of packaging bags, in particular to a packaging bag that can be stacked without extrusion. Background Technique

[0002] A packaging bag refers to a bag used for packaging various articles, which makes it convenient to transport goods during the production and circulation process and easy to store. It is widely used in daily life and industrial production. Actual figures show that 80% of the plastic bags after use are finally transported to landfills for disposal like general garbage, and only 7% of the plastic is recycled. Existing packaging bags need to be stacked for storage and transportation during storage and transportation. During the stacking process, the packaging bags stacked below are squeezed by the gravity of a large number of packaging bags above, and are extremely prone to wrinkling and deformation. In order to improve the efficiency of goods transportation, a packaging bag is needed, but the existing packaging bags still have the following deficiencies:

[0003] For example, the utility model with the application number 202320782394.5 discloses a stepped valve-opening packaging bag. The bag body of this utility model is composed of an upper bag and a lower bag. The upper bag and the lower bag are integrally formed structures, and a step is formed at the connection between the upper bag and the lower bag. After an object is placed in the bag body, the step can play a certain supporting role for the object, thereby reducing the pressure on the bottom cover and avoiding the tearing of the bottom cover caused by excessive pressure on the bottom cover. However, for comparative documents similar to the above application, when existing packaging bags are in use, since most packaging bags are transported by stacking, the packaging bags are easily torn and damaged due to close friction, thereby increasing production costs and causing problems such as a decline in the practicality and a reduction in the use efficiency of the packaging bags.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a packaging bag that can be stacked without extrusion is proposed. Content of the Utility Model
