Description

Technical Field

[0001] The utility model relates to the field of packaging devices, in particular to a plastic bag packaging device. Background Art

[0002] A plastic bag is a bag-shaped container used to package items, usually made of plastic material. After some families open the plastic bag, they need to seal the bag because the items in the bag have not been used up and the items need to be packaged and preserved. A bag sealing machine is needed to seal the opening of the plastic bag. Therefore, a plastic bag sealing device is proposed.

[0003] Most of the existing plastic bag sealing machines use single-sided hand-pressure bag sealing machines, and the two ends of the single-sided hand-pressure bag sealing machines cannot press the bag opening at the same time, which may cause one side of the plastic bag to overheat while the other side is still sticky due to the different time of pressing the bag opening. At the same time, after the bag is sealed, the heating wire cannot be effectively and quickly dissipated, which may cause the heating wire to scald people. For this reason, technical improvements are urgently needed. Utility Model Content
