[0002] Plastic packaging bags are made of plastic as raw materials and are used to produce various daily necessities. They are widely used in daily life and industrial production, but this temporary convenience brings long-term harm. Commonly used plastic packaging bags are mostly made of polyethylene film, which is non-toxic and can be used to hold food. At present, when plastic packaging bags are produced, they need to be punched due to demand.

[0003] For example, the Chinese patent application number 201922256258.9 is a punching device for plastic packaging bags.

[0037] By adopting the above technical solution, the device can compress the plastic packaging bags through the compression component, so that the device can quickly compress and fix the plastic packaging bags of different thicknesses as needed.
