What is Gravure Ink? Gravure (Rotogravure) inks are solvent-based ink with low viscosity, which can be quickly dried by vaporization. The advantages of gravure printing lie in the high, consistent, and continuously reproducible print result. Further, the benefit of fast-drying ink contributes to an immediate post-finishing of the printed goods. The ink is usually used in commercial printing of flexible materials, such as magazines, postcards, corrugated cardboard, plastic films, aluminum foil for product labeling, and all consumer packaging. What resins Sunman can supply? Sunman has a variety of raw materials being offered for gravure inks. These are the following: 1. CEVA Resin It is the resin for gravure reverse printing on flexible packaging film such as OPP, BOPP, etc. 2. Chlorinated Polypropylene (CPP) Resin It enhances the adhesion to the substrates such as BOPP, OPP, etc. It is also the main resin for gravure reverse printing. 3. Polyamide resin It is a resin for gravure suface printing. It can be used on paper, PE, and PP substrates. 4. Vinyl chloride and Vinyl isobutyl ether resin It is a resin for gravure reverse printing on flexible packaging substrates such as BPP, OPP, etc. It improves the compatibility of EVA and CPP resins. 5.Vinyl chloride and Vinyl acetate copolymer resin It is a modifier resin to improve flexibility, adhesion, and heat-sealing properties of the ink. It is a resin for gravure reverse printing inks. 6. Polyurethane resin It is one component, high performance PU resin for gravure lamination or surface ink. It has excellent adhesion property on OPP, PET, NY and other films.

Zirconia beads, a kind of ceramic grinding media, have features of good quality, no fracture, stable performance, reliable quality and long service life. They're low comprehensive operating cost which can effectively ensure that the abrasive material is not polluted, and maintain the high purity of the abrasive material. The high density of the zirconia ceramic beads can improve the grinding efficiency. And due to the low wear rate of zirconia mill balls, the stability of the grinding process condition can be effectively ensured. The stability and consistency of the quality of the raw material facilitates process control and management. The Benefits of Zirconia Beads: - High crushing strength and fracture durability superior wear resistance which has no any break under high speed impace. They can improve the efficience of grinding and no contamination. - High density and excellent grinding efficiency for grinding materials down to Nano size. - Smooth surface, good sphericity and low self-loss. - Significant cost and waste reduction. Application: It is suitable for grinding and dispersion of ultra-finematerial such aselectronic ceramics, magnetic materials, highpurity ceramics material such as alumina oxide, silicon oxide, zirconium silicate and titanium dioxide: foodstuffs, cosmetic and pigment, inks, paint and coating materials.

The PU resin for printing ink, also called ink binder. PU ink binder for gravure is also known as PU resin for gravure and flexography ink, polyurethane ink binder for food packaging lamination inks, high-bonding-strength flexography printing ink binder, polyurethane flexible packaging printing ink binder.

Flexo (Flexography) Inks are inks transferred by the process of flexography, primarily used in the printing of packing materials, for example, cardboard boxes, brown corrugated cardboard, paper bags and plastic bags, newspapers, etc. There are several types of ink which are mainly water-based, solvent-based, and UV curable. The flexo inks, like Gravure inks, have low-viscosity, characterised as fluids. This enables faster drying and, as a result, faster production, which results in lower costs. The flexo inks and method of printing continue to grow in popularity due to its low cost and environmentally friendly nature. General properties of Flexo Printing Ink Type Characteristic Use Co-Solvent Must use a synthetic resin plate that is highly resistant to solvents as it contains alcohols & esters. Makes a wider variety of resins available. Application on Al-foil, Polyolefin, Polyester Nylon, etc. Interior/exterior printing Alcohol May apply on a wide range of boards as it contains Ethanol, IPA or other Glycol that cause minimal effect to the plate. Tendency of absorbing moisture. Al exterior printing OPP, PE exterior surface printing Water Inflammable with no solvent residue. May be diluted with water. Harder to re-fuse. Limited dryness.
