Problems solved by technology

Double PE paper cup printing is to print graphics and text on the outer PE film. Since the PE film is a non-absorbent substrate and has low surface tension, the water-based inks currently used in the market have poor adhesion and poor water resistance when used for double PE paper cup printing. Not resistant to alcohol, not resistant to freezing, not resistant to high temperature and other defects, can not meet the use of cold drink paper cups and post-press processing requirements

Abstract

The invention relates to a water-based flexographic ink system dedicated to dual-PE paper cups. The ink system, which consists of water-based flexographic colored ink dedicated to dual-PE paper cups and varnish capable of being contacted with food, is used for the flexographic printing of dual-PE paper cups, and can effectively meet the printability requirement and the post-press finishing requirement. The varnish can effectively isolate the colored ink from being directly contacted with food and beverage, thus ensuring the hygienic safety of paper cups. The invention has the advantages of excellent properties, no toxin, no smell, safety, environment-friendliness and low overall cost, and has a broad market prospect.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to a special water-based flexographic ink system for double PE paper cups. Background technique [0002] With the development of society and the improvement of people's living standards, disposable paper cups are becoming more and more popular due to their advantages of safety, environmental protection, convenience, hygiene, low price and degradability, and have a wide market demand. Due to the needs of product promotion and promotion, the outer wall of paper cups generally needs to print product logos and exquisite color patterns, and the small molecular components remaining in the dried ink layer may permeate and migrate from the outer wall of the paper cup to the inner wall of the paper cup. In addition, paper cups are generally stored and transported in a stacked package. Due to the vibration and friction between the inner and outer walls of adjacent paper cups, the printi...
