Technical Field

[0001] The utility model relates to the technical field of plastic bag production, in particular to an automatic bundling device for plastic bag production. Background Art

[0002] Plastic bag packaging bags are a double-layer plastic film with storage and packaging functions made of plastic as the main raw material. They are an indispensable auxiliary item in people's production and life. People often use plastic bag packaging bags for storage and packaging, making the items inside easy to carry or store. They are widely used by people because of their low price, small weight, and convenient storage. After the plastic bag packaging bags are produced, they need to be rolled into bundles for easy sale and use.
