Problems solved by technology

In order to ensure that the surface of the plastic film has good printability, corona treatment is often carried out on the surface of the plastic film, which can effectively improve the wettability and adhesion of the film surface, but the surface of the PE film in the prior art is treated by corona The ink adhesion of the rear ink layer is not good, and the ink is easy to fall off after repeated pullbacks

Abstract

The invention provides a preparation method of a plastic woven bag color printing film. The preparation method comprises the following steps of S1, mixing ink solvent raw materials to prepare an ink solvent for storage for later use; S2, putting ink coloring raw materials into a stirrer for dispersing and stirring to prepare a coloring mixture; S3, pouring the stirred coloring mixture into the inksolvent, and adjusting the pH value to 8-9 to prepare printing ink; S4, pouring outer-layer coating film raw materials into a high-speed mixer for uniformly stirring to form a coating film raw material mixture; S5, putting the coating film raw material mixture into a co-extrusion blow molding film machine for blow molding; S6, cooling and forming the blow-molded coating film; S7, carrying out corona treatment on the cooled and formed coating film; and S8, printing the printing ink on the outer-layer coating film, enabling the printing ink to form an ink layer, and drying the color printing film. According to the preparation method, the plastic woven bag outer film is good in wear resistance, high in corona resistance, good in tensile property and easy to color.

Description

technical field [0001] The invention relates to the technical field of plastic woven bag production technology, in particular to a method for preparing a plastic woven bag color printing film. Background technique [0002] Plastic woven bags are the main material of flexible packaging, and are widely used in industrial and agricultural production products and raw material packaging. The printing process in the production process of plastic woven bags is a key link in the production process of woven bags. The printing process of woven bags usually uses ink printing, which is to make text, pictures, photos, anti-counterfeiting and other originals through plate making, ink application, pressurization and other processes, so that the ink is attached to the PE outer film, and then the PE outer film is covered on the woven bag. On the outside, it is prepared as a plastic woven bag with color printing patterns on the surface. In order to ensure that the surface of the plastic film...
