[0001] The present application relates to the technical field of plastic film processing equipment, more particularly, the present application relates to a novel plastic film point breaking device. BACKGROUND

[0002] The film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins is used for packaging and as a coating layer. The proportion of plastic packaging and plastic packaging products in the market is increasing, especially the composite plastic soft packaging, which has been widely used in food, medicine, chemical industry and other fields, among which the proportion of food packaging is the largest, such as beverage packaging, frozen food packaging, steamed food packaging, fast food packaging and other products, which brings great convenience to people's life.
