[0002] Stand-up bags are made of plastic and are used to package various items in life. They are widely used in daily life and industrial production. In the production process of packaging bags, the use of die-cutting machines for cutting is indispensable.

[0003] In the prior art, for example, Chinese patent number CN220517679U discloses a die-cutting device for a self-supporting packaging bag. In the patent, the characteristics of the elastic plate give it a certain bending ability. When the self-supporting bag is die-cut on the elastic plate, the cutting force will cause the elastic plate to deform slightly. This deformation generates stress around the cutting point, so that the edges of the two bag films of the packaging bag are pushed apart, thereby causing them to separate automatically without affecting the self-supporting effect of the packaging bag.
