Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene films, in particular to a polyethylene film processing and slitting mechanism. Background Art

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is used for packaging and as a coating layer. It is widely used in food, medicine, chemical and other fields, bringing great convenience to people's lives.

At the same time, when the staff is slitting the film, they lack the ability to adjust the tension of the film, which affects the slitting effect. A polyethylene film processing and slitting mechanism is now needed to solve the above technical problems. Utility Model Content
