Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging bags, in particular to a vacuum packaging bag for fish processing. Background Art

[0002] Vacuum packaging bags, also known as reduced pressure packaging, are made by extracting all the air in the packaging container and sealing it, maintaining the bag in a highly reduced pressure state. The scarce air is equivalent to the low oxygen effect, which makes it impossible for microorganisms to survive, so as to keep the fruit fresh and free of disease and rot. In fish processing, the processed fish meat is placed in vacuum packaging bags for easy later sales and storage.

[0003] When the vacuum packaging bag is evacuated, the air pipe needs to be pulled out to seal the air pipe. However, when the air pipe is pulled out, the air pipe cannot be blocked in time, which will cause some air to enter the vacuum packaging bag again, thereby affecting the preservation effect of the fish meat in the vacuum packaging bag in the later stage. In order to maintain the quality of the fish meat, ice cubes are usually used to preserve it. However, in daily use, such as when going out camping, in order to better preserve it, it is necessary to carry a container, put the fish meat in the container, and add ice cubes for preservation. It is very troublesome and inconvenient to use. For this reason, we propose a vacuum packaging bag for fish processing. Utility Model Content
