Definition:

The invention relates to the technical field of film printing. The plastic film double-sided printing process and equipment use a driving component to drive the winding roller and the feeding roller to synchronize rotation, ensure the effective tensioning of the plastic film printing process, provide preliminary protection for the quality of double-sided printing, and through the gas transmission component to the blow box and the blow cylinder, accelerate the cooling of the surface of the plastic film after printing, and avoid the ink material contamination when the plastic film is rolled up after printing At the same time, the use of a number of cooling rolls to increase the contact area of the plastic film, further improve the cooling of the plastic film after printing, at the same time, to provide protection for the tensioning of the plastic film, further improve the quality of the plastic film printing, and the use of the printing box, the winding box and the feeding box, to achieve closed printing, effectively isolate the dust, and then the plastic film The neatness is guaranteed.

The printing process of a plastic bag comprises the following steps: The printing process of a plastic bag is characterized in that it comprises the following steps :S1, the plastic bag is treated with electrostatic removal; S2, adjust the tension of the printed surface of the plastic bag; S3, printing of plastic bags; S4, the printed plastic bags are dried by ultraviolet low temperature. The invention also comprises a plastic packaging bag equipment, which comprises a winding roller, a first guiding roller, a second guiding roller, a third guiding roller, an electrostatic removal mechanism, a tension regulating mechanism, a printing mechanism, a drying mechanism and a winding roller; The electrostatic removal mechanism is arranged between the first guide roller and the second guide roller, comprising a first support table and a electrostatic removal brush; The tension adjusting mechanism is arranged between the second guide roller and the third guide roller; The drying mechanism is arranged between the printing mechanism and the winding roll.

For packaging and printing enterprises, doing a good job of green printing materials, printing graphic design, green plate making process, green printing process, green post-press processing technology, environmentally friendly printing equipment, print waste recycling and recycling is an important content of the implementation of green printing. In recent years, the packaging and printing industry has developed rapidly and has become an important pillar of the printing industry. In the green printing system is even more important. The third green printing standard – gravure printing will be formally implemented, directly pointing to a large number of packaging and printing enterprises.
