Polyethylene heat shrinkable film gravure printing process

Abstract

The invention relates to a polyethylene heat shrinkable film gravure printing process which comprises the following steps of: (1) unwinding a polyethylene heat shrinkable film; (2) carrying out unwinding drawing; (3) carrying out inking by a drop roller; (4) scraping ink by a scraper; (5) carrying out gravure printing; (6) drying ink; (7) cooling a printed object; (8) carrying out multiple color class overprinting, wherein the steps (3), (4), (5), (6) and (7) are sequentially repeated; (9) carrying out winding drawing; (10) winding; (11) checking the quality; (12) stripping; (13) sealing and cutting; and (14) carrying out finished product packaging to obtain a finished product, wherein when the step (6) is implemented, the ink printed on the surface of the polyethylene heat shrinkable film is dried by modes of feeding hot blast by an air blower and circulating the hot blast by a drying box and related equipment comprises an air energy heating device, the air blower, an external heating box, a suction fan and the drying box with an effect of an air chipper. The polyethylene heat shrinkable film gravure printing process is used for carrying out gravure printing on the polyethylene heat shrinkable film.

Description

technical field [0001] The invention relates to the technical field of gravure printing, in particular to a polyethylene heat shrinkable film gravure printing process. Background technique [0002] Current situation of gravure printing in the prior art: gravure printing is the main printing method of packaging printing, and its characteristics are that it can truly reproduce the effect of the original manuscript, the combination of printed colors and patterns is rich and clear, the ink color is saturated and thick, and the color is bright and bright. Compared with flexographic transfer printing, lithographic offset printing, etc., in addition to the above advantages, gravure printing also has the advantages of low equipment investment cost, mature technology, strong comprehensive processing ability, and low ink cost. There are a wide range of media suitable for gravure printing, among which plastic materials include PVC, PET, PE, NY, CPP, PP, BOPP, etc. [0003] The state o...
