BACKGROUND ART

Plastic wrapping film plays a very important role in agricultural harvesting equipment, and is used to wrap crops such as hay, cotton, silage or corn to protect them from sunlight, rain and oxygen. The film has the functions of waterproofing, heat preservation, degradation, wind prevention, air permeability, etc., and can extend the storage time of crops in the field, thereby improving the harvesting efficiency and reducing losses. During use, farmers can quickly and evenly wrap the film on the surface of the crop through a special wrapping machine to ensure the tension and tightness of the film. Meanwhile, to facilitate the subsequent harvesting and transportation the wrapping film can also be simply cut and unpacked as needed.

In related technologies, to facilitate the packaging film to be rolled up, the packaging film is cut into a number of small segments.
