Description

Plastic film flattening device Technical Field The utility model relates to the technical field of plastic film processing, in particular to a plastic film flattening device. Background Films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging, and as film layers. Plastic packages and plastic packaging products have a larger and larger share in the market, particularly composite plastic flexible packages, have been widely applied to the fields of food, medicine, chemical industry and the like, wherein the plastic packages and the plastic packaging products have the largest proportion, such as beverage packages, quick-frozen food packages, steamed food packages, snack food packages and the like, and the plastic packaging products bring great convenience to life of people. The plastic film flattening device is mainly used for flattening plastic films in the production or processing process, and removing wrinkles, bubbles and irregular shapes on the surfaces of the films so as to ensure the smooth and uniform surfaces of the films. The film after the treatment can be better suitable for subsequent processing, such as printing, packaging and the like, ensures the production quality, has the main functions of removing wrinkles and waves, and can eliminate the defects of wrinkles, waves and the like on the surface of the film by the pressing action of a roller, thereby ensuring the flatness of the film. The surface is uniform, and the surface of the film can be ensured to be smooth and uniform by the flattening device, so that the film is suitable for subsequent processing operations such as printing, coating, packaging and the like. The processing precision is improved, namely the flat film can improve the processing precision of the subsequent production link, and the film is not easy to tear and deform in the processing process. The visual effect is improved, namely the surface of the film is smoother, the appearance of the film can be improved, and particularly in a transparent film, the influence of the surface flatness on the visual effect is important.
