Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of film blowing machine, specifically relates to a mother film automatic inflation device. BACKGROUND

[0002] At present, packaging bags are widely used in daily life and work due to their convenient and simple characteristics in use and carrying. Plastic products include polyethylene plastic products, polypropylene plastic products and polyvinyl chloride plastic products. These plastic products not only can protect products, facilitate transportation, but also can promote sales and beautify products. In the production of plastic products, an extruder is used to melt plastic particles, and a film blowing device is used to continue heating the molten material to the most suitable temperature required for film blowing, and the molten material uniformly overflows from the annular interlayer, and the uniformly blown gas in the annular interlayer blows the molten material into a plastic film.

[0003] ‌The secondary inflation of the mother film refers to the process of heating and inflating again after the first inflation of the film. Specifically, after the first inflation of the film, the film is heated again and inflated for the second time in the viscoelastic state, and after cooling and setting, a heat-shrinkable film with a certain shrinkage rate can be obtained. The advantages of the secondary inflation of the mother film are: (1) high transparency: the film inflated for the second time has good transparency, which can better show the appearance of the packaged product; (2) easy to shrink: the film shows good shrinkability in the shrinkage process, which can tightly wrap the product; (3) high strength: the film inflated for the second time has high strength, which can better protect the packaged product; (4) adjustable shrinkage rate: the shrinkage rate can be adjusted according to user requirements, which has high operability.
