Preprinted ink for high-temperature resistant carton

Abstract

The invention relates to the technical field of ink, in particular to preprinted ink for a high-temperature resistant carton. The preprinted ink comprises the following components in percentage by weight: 10 to 30 percent of protein resin, 10 to 40 percent of acrylic resin solution, 2 to 10 percent of assistant, 30 to 60 percent of acrylic color paste and water. The preprinted ink has the advantages of stable performance, good lustrousness, simple preparation, low cost, environment friendliness, innocuity, and contribution to safe protection and environmental protection; the preprinted ink has the most important characteristic of using the protein resin to improve the high-temperature resistance by a higher level compared with other water-based preprinted high-temperature resistant ink, such as ink using acrylic resin.

Description

Technical field: [0001] The invention relates to the technical field of inks, in particular to a pre-printed ink for high-temperature resistant cartons. Background technique: [0002] The traditional production of color corrugated cartons is to print directly on the die-cut cartons by flexographic printing technology. The cartons produced by this technology are simple in pattern, dirty in color and not bright enough, and the surface of the carton may be uneven due to excessive pressure. Corrugated phenomenon, this technology is generally used in lower-grade packaging. [0003] Then came the lithographic offset printing technology to produce cartons, using offset printing on a single carton surface paper, and then using a laminating machine to bond the printed surface paper and corrugated paper, and then die-cutting. The cartons produced by this method are rich in patterns, bright in color and saturated, but the production efficiency is still low, and the stability of produc...
