Problems solved by technology

[0003] Since the double PE base paper is a product obtained by double-sided coating of raw wood pulp paper, the surface tension of the PE film is low, and it is easy to print a water-based ink with a high surface tension on its surface, which is prone to poor adhesion, water resistance, and high resistance to printing inks. Phenomena such as low temperature
[0004] At present, the water-based ink used in double PE paper cup printing in the prior art is generally composed of two parts: color ink and varnish that can be in contact with food. Among them, the color ink has the properties of non-toxic, tasteless, bright colors, etc., which can basically meet the requirements of customers. , but if the color ink is not varnished, there will be disadvantages such as not wear-resistant, not waterproof, and not resistant to high and low temperatures, so there must be a varnish process, which increases the production cost of the printing factory

Abstract

The invention belongs to the technical field of ink preparation, and particularly relates to glazing-free double-PE water-based flexible ink and a preparation method thereof. The glazing-free double-PE water-based flexible ink comprises the following raw materials in percentage by weight: 40-60% of varnish and 40-60% of water-based color paste, wherein the varnish comprises the following raw materials in percentage by weight: 60-80% of soft emulsion, 0-10% of hard emulsion, 0-25% of water-soluble resin liquid, 1-3% of a scratch-resistant agent, 1-3% of a crosslinking agent, 0-3% of a water-resistant agent, 0-1% of a leveling agent, 0-8% of a film-forming auxiliary agent, 0.1-0.5% of a defoaming agent and the balance of deionized water. The glazing-free double-PE water-based flexible ink omits a glazing process in the printing process, so that the cost is saved, and a double-PE paper cup printed by using the ink is high in gloss, colorful, beautiful, water-proof, wear-resistant, high-temperature-resistant and freezing-resistant.

Description

technical field [0001] The invention belongs to the technical field of ink preparation, and in particular relates to a coating-free double PE water-based flexographic ink and a preparation method thereof. Background technique [0002] Fast food such as McDonald's and Pepsi widely use double PE paper cups, paper bowls and paper buckets to hold hot coffee and cold drinks, etc. Yili yogurt has also begun to use double PE paper cups. For the needs of the brand, exquisite patterns need to be printed. For the needs of environmental protection, manufacturers have required printing companies to use water-based inks for printing. [0003] Since the double PE base paper is a product obtained by double-sided coating of raw wood pulp paper, the surface tension of the PE film is low, and water-based ink with high surface tension should be printed on its surface, which is prone to poor adhesion, water resistance, and high resistance to printing inks. Low temperature etc. [0004] At pr...
