Abstract

The invention relates to a blow molding preparing method for a plastic film. A blow molding preparing device for the plastic film is used. The blow molding preparing device for the plastic film comprises a guide frame, an extruding machine, a guiding and fixing device, a traction device and a cutting device. The extruding machine is installed at the lower end of the interior of the guide frame. The guiding and fixing device is arranged above the extruding machine. The traction device is arranged on the right side of the guiding and fixing device. The cutting device is arranged between the traction device and the cutting device. By means of the blow molding preparing method for the plastic film, a multiple guiding and fixing design concept is adopted for conducting plastic film production,an adaptive guiding, clamping and fixing structure is adopted for the upper and the lower end of the initial-stage tubular plastic film, the forming size of the tubular plastic film and the completeness of the whole body of the plastic film are ensured, and the forming quality of the tubular plastic film is improved.

Description

technical field

[0001] The invention relates to the technical field of plastic film blow molding production, in particular to a preparation method of plastic film blow molding. Background technique

[0002] Plastic film refers to films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It can be used for packaging and as a coating layer. The market share of plastic packaging and plastic packaging products The share is increasing, especially composite plastic flexible packaging, which has been widely used in food, medicine, chemical industry and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, retort food packaging, fast food Packaging, etc. These products have brought great convenience to people's life. When plastic film is used as food packaging, it is required to have high surface free energy and large wet tension to facilitate printing ink, adhesive or...
