Problems solved by technology

[0003] However, when the common ink products on the market meet the requirements of dry lamination process, they cannot meet the process requirements of extrusion lamination and solvent-free lamination at the same time.
Because during the extrusion compounding process, the printing ink is in contact with the high-temperature cast plastic film, and the ink needs high temperature resistance, otherwise it is easy to cause insufficient composite strength
In the solvent-free composite process, the ink film is easily dissolved by the low molecular weight of the solvent-free adhesive during the bonding process with the ink film, resulting in quality problems such as darkening of the composite product, exposure of the aluminum layer, and white spots.

Abstract

The invention provides printing ink for various compound processes. The printing ink comprises the following raw materials: 30% modified polyurethane resin liquid, 15% modified binary and ternary vinyl chloride and vinyl acetate copolymer mixed liquid, pigment, fillers, polyethylene wax, a special assistant, n-propyl acetate, isopropanol, ethyl acetate and a silane coupling agent. The printing ink is improved aiming at a compound process technology of flexible package printing; by improving components in a formula system, especially adopting the silane coupling agent and the special assistant, the permeation of an ink printed product on low-weight molecules of solvent-free glue is improved to the maximum extent, the high-temperature resistance of the printing ink in an extrusion compound process is improved, the problems of white spots and low compound strength of a compound product are solved, and the product quality is ensured.

Description

technical field [0001] The invention relates to an ink product, in particular to an ink suitable for multiple composite processes in flexible packaging printing. Background technique [0002] At present, the composite process of flexible packaging enterprises has developed from the original single dry composite to multiple composite methods such as dry composite, extrusion composite and solvent-free composite. Among them, extrusion compounding and solvent-free compounding are widely used by many enterprises because of their fast compounding machine speed, no solvent residue, and low cost. [0003] However, when the common ink products on the market meet the requirements of the dry lamination process, they cannot meet the process requirements of extrusion lamination and solvent-free lamination at the same time. Because during the extrusion compounding process, the printing ink is in contact with the high-temperature cast plastic film, and the ink needs high temperature resis...
