Description

Technical Field

[0001] The utility model relates to the technical field of soft packaging, in particular to a sealing device for plastic soft packaging. Background Art

[0002] Flexible packaging refers to packaging whose container shape can change after filling or taking out the contents. Compared with other packaging methods, flexible packaging has many advantages such as barrier properties, easy printing, and low cost, and is favored by product manufacturers and consumers. Therefore, flexible packaging plays an increasingly important role in many fields. In the packaging industry, flexible packaging has become one of the most important packaging forms for shelf sales with its gorgeous colors, rich functions, and diverse forms of expression. The progress of the domestic flexible packaging industry has greatly promoted the development of industries such as food and daily chemicals. In the prior art, the announcement number CN212530294U discloses an automatic sealing machine for flexible packaging. When using this sealing machine, the staff inserts a suitable sealing piece into the slot and locks the sealing piece with a locking bolt.
