High-temperature steam endurance ink for spraying code and printing

Abstract

The invention relates to high-temperature steam endurance ink for spraying code and printing, containing one or more organic solvents, resin and coloring agents. In addition, the consistency of the ink is 2.8-6.2CP / 25DEG C, the conductivity is 500-1,500muS and the surface tension is 27-30Dyn / cm. The high-temperature steam endurance ink for spraying code and printing can be applied to the surfaces of various packaged objects required to be treated at high temperature. The mark and the substrate adopting the high-temperature steam endurance ink have strong adhesive force and favorable adhesiveness and cannot fade, fall off, permeate and shift after being subjected to high-temperature digestion. The dried mark can be also scraped by a cleaning agent.

Description

technical field

[0001] The invention relates to a high-temperature-resistant cooking ink for inkjet printing, which belongs to the high-temperature-resistant cooking printing ink for inkjet printers. Background technique

[0002] Continuous inkjet printing system (CIJ) is a relatively complex inkjet system. Its biggest advantage is that it can achieve high-speed printing when printing numbers or letters. The ink used in this system is characterized by low viscosity and must be able to Chargeability and breakability.

[0003] According to the printing substrate of the marking information and the use environment, there are also different requirements for the ink used. For example, in many food packaging products, after the packaging is sealed, it is necessary to print the identification information, and in order to sterilize and make the finished product, it needs to be cooked at high temperature. In the high-temperature cooking process, it is required that the printed infor...
