What are good properties of Vinyl Resin for gravure composite ink?
Gravure composite ink is widely used in the printing of food, medicine, calendar and other products. The effect of vinyl resin on gravure composite ink. It has good ester solubility and good compatibility with polyurethane.Ternary hydroxyl vinyl chloride resin can resist boiling and cooking, has excellent dispersibility to pigments, and provides composite strength. High temperature and boiling resistant intaglio plastic composite ink is made of vinyl resin and polyurethane as binder, a series of special additives and organic solvents, and organic pigments with high temperature resistance, which are evenly stirred, dispersed, grinded and bonded. It is suitable for printing in low-speed to high-speed plastic films. The substrates are usually PET, BOPP, NYLON (nylon) and aluminized composite plastic films. The printed products can be used not only in common composite process, but also in high-temperature cooking process. The ink film solvent residue is low, odorless, non-toxic, environmentally friendly and safe, and can be used in food and drug packaging, which meets the hygienic requirements. High temperature and boiling resistance intaglio plastic composite ink has the following characteristics: (1) High adhesion fastness, suitable for a variety of printing films; (2) Low viscosity, good leveling, high solid content, bright color, high color concentration,suitable for multi-layer printing; (3) Good printing adaptability, good ink transfer, suitable for different machine speed and plate depth; (4) Printing can resist high-temperature cooking, generally, when one component is used, it can be boiled up to (90-100), (100-120), (3-4%) curing agent is added to two-component printing, which can improve the high-temperature resistance, film-forming performance, printing adaptability and composite fastness of printing ink.
