Improvement of Composite Strength of Gravure Composite Ink by Vinyl Resin

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, good dot reproducibility, 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.

Vinyl Resin For Gravure Composite Printing Ink

Gravure composite inkis suitable for gravure printing presses, printing processed polyolefin and polyester films, and laminating a film (eg. polyethylene) by bonding heat. It is composed of chlorinated polyolefin resin (vinyl resin), pigments, benzene, ketone solvents, stabilizers, antistatic agents, etc. The liquid ink is volatilized and dried by dispersion. Technical quality indicators include adhesion, composite peeling strength, solvent residue, dryness, viscosity and fineness. The imprinting does not change color, dissolve, sublimate, react with adhesives or wrinkle the film because of ink when the temperature of thermal recombination is above 310 C and the pressure of composite wire is between 0.9 and 3.6 MPa. Used for printing food, medicine, calendar and other products.

Characteristics of ester-soluble intaglio composite ink: A new type of intaglio lithographic ester-soluble series vinyl resin composite ink is specially developed for light packaging printing and compounding of BOPP film. It has a wide range of printing adaptability from low-speed to high-speed. In compounding, it has excellent compounding. Requirements of high quality composite ink: 1. Excellent printing adaptability, good scraper adaptability, scraper line, less fog phenomenon, can adapt to all kinds of printing speed. 2. Excellent transfer performance and excellent color reproduction performance. 3. Low residual solvent and less residual odor. 4. Composite adaptability is excellent. In all kinds of composite processes, dry compounding, solvent-free compounding and PP extrusion can obtain stable composite strength.

Vinyl resin used in intaglio composite ink, model: MVAH, main performance: in line with FDA standards, with good compatibility with polyurethane, soluble in ester or ketone mixed solvents, transparent and clear solution; provide wettability and dispersibility for pigments, can be used as abrasive resin to improve the pigments color development performance, good. Film forming, solvent release. The ink is resistant to boiling (100 degree boiling, 135 degree boiling), and has good composite fastness with polyurethane adhesives. It is mainly used in water-resistant and steaming composite ink for food packaging. Corresponding model: Solbin A. Main customers: DIC, TOYO, SAKATA.
