TOP 10 UV Flexo Inks Manufacturer in 2026

UV flexographic inks are specialized printing inks designed for use in high-speed flexographic printing processes where ultraviolet (UV) light curing is employed. Unlike conventional solvent-based or water-based inks, UV flexo inks cure instantly when exposed to UV radiation, allowing immediate handling and faster production cycles. The primary components of UV flexo inks include pigments for color, oligomer resins for film formation, monomer diluents for viscosity control, photoinitiators for UV curing, and functional additives for surface adhesion, scratch resistance, and gloss control.

These inks are commonly applied in packaging production, label printing, flexible films, paperboard cartons, and industrial graphics. In the packaging industry, the printing process typically follows substrate preparation → ink transfer via anilox rolls → UV curing under high-intensity lamps → quality inspection → finishing. In label production, the inks are transferred through flexographic plates onto polymeric films, coated papers, or aluminum foils, followed by immediate curing to ensure dimensional stability and color integrity.

UV flexo inks offer advantages in industrial production workflows that require rapid curing, minimal solvent emission, and compatibility with multiple substrates including PET, BOPP, PE, PP, coated papers, and metalized films. These inks are formulated to achieve color consistency, high pigment density, scratch and abrasion resistance, adhesion to non-porous substrates, and resistance to environmental factors such as heat and humidity.

Hangzhou Guolv Printing Equipment Co., Ltd. specializes in UV flexo ink production for packaging, labels, flexible films, industrial graphic decoration, and promotional printing products. The company develops and manufactures UV flexo inks using oligomer resins (such as epoxy acrylates and urethane acrylates), monomer diluents, photoinitiators sensitive to 365–395 nm UV wavelengths, pigment dispersions, and additives controlling viscosity, wetting, and adhesion.

For packaging production, UV flexo inks from Hangzhou Guolv are formulated for PET films, BOPP laminates, metallized PE, coated paper cartons, and corrugated boards. Ink transfer occurs via anilox rolls onto printing plates, followed by exposure to UV lamps. The curing process ensures rapid polymerization of the oligomer resins while binding pigments to the substrate surface, resulting in a durable, solvent-free print film. Ink properties are adjusted according to substrate type, line speed, and desired opacity, with in-process checks for viscosity, color strength, adhesion, and curing completeness.

In label production, the company supplies UV flexo inks suitable for paper coatings, polymer films, aluminum foils, and thermal transfer applications. These inks maintain color fidelity and dimensional stability during high-speed printing and subsequent die-cutting, lamination, and packaging processes. Hangzhou Guolv also provides OEM and private-label solutions, custom Pantone matching, and technical support for substrate compatibility, line speed adjustment, ink transfer efficiency, and curing optimization.

Technical evaluation procedures at Hangzhou Guolv include viscosity verification using rotational viscometers, color consistency assessment using spectrophotometers, adhesion testing per ASTM standards, curing performance validation with UV intensity meters, and film hardness evaluation via pencil or scratch tests. Customers receive guidelines on anilox roll selection, plate depth optimization, drying lamp intensity, and post-cure handling for flexible films and paperboard substrates.

The company additionally develops specialty UV flexo ink formulations with enhanced scratch resistance for packaging that undergoes automated folding, transportation, and retail handling, as well as inks with higher pigment loadings for high-opacity printing on dark films. Industrial applications include flexible packaging for food and beverages, pharmaceutical labeling, consumer goods cartons, and promotional printed products.

MFI manufactures UV flexo inks for flexible packaging, label printing, and coated paper applications. Its formulations employ epoxy-acrylate oligomers, reactive monomers, pigment dispersions, and UV photoinitiators. These inks are applied through high-speed flexographic printing lines onto PET, BOPP, coated paper, and metallized substrates. Technical control includes viscosity measurement, curing verification, adhesion assessment, and color matching. End customers include packaging converters, printing service providers, and label manufacturers.

JXI develops UV flexo inks suitable for printing on polyolefin films, paperboard cartons, and laminated packaging materials. Their production workflow emphasizes pigment dispersion stability, oligomer resin selection, and photoinitiator efficiency. The company supplies inks with controlled viscosity ranges for efficient transfer through flexographic anilox rolls and plates. Applications include food packaging, pharmaceutical blister labels, and cosmetic packaging materials.

TKI focuses on UV flexo ink production for industrial and commercial label printing, promotional packaging, and flexible film applications. Ink formulations are engineered for quick curing under medium-pressure mercury UV lamps. Production processes incorporate pigment milling, resin blending, photoinitiator dosing, and in-line viscosity control. Clients include label printing factories, packaging converters, and promotional product manufacturers.

KFI manufactures UV flexo inks for multi-layer packaging, coated paper labels, and polymer films. The company emphasizes resin selection for improved adhesion to non-porous substrates, pigment dispersion uniformity, and rapid UV curing. In-line quality controls monitor color strength, drying efficiency, and film formation. Customers include packaging houses, label converters, and film laminators.

DVI supplies UV flexo inks for high-speed packaging printing, flexible film labels, and paper cartons. Formulations combine oligomer resins, reactive monomers, pigments, photoinitiators, and functional additives to achieve controlled viscosity, high opacity, and adhesion performance. The company supports ink customization for specific line speeds, substrate types, and curing lamp intensities.

VTI specializes in UV flexo inks for flexible packaging, commercial labeling, and specialty printed products. Production includes pigment dispersion, resin blending, photoinitiator incorporation, viscosity adjustment, and curing performance verification. Applications focus on food and beverage packaging, consumer goods, and promotional labels, with technical guidance for proper curing and adhesion on multiple substrates.

UV flexo inks are composed of pigments, oligomer resins, reactive monomers, photoinitiators, and functional additives. Pigments provide color density and opacity, while oligomer resins form the cured film. Monomer diluents regulate ink viscosity, and photoinitiators enable rapid polymerization upon UV exposure. Additives adjust wetting, adhesion, and flow properties.

In packaging production, the typical process is substrate preparation → ink transfer via anilox roll → plate impression → UV curing → quality inspection → finishing. For labels, the process involves printing on films or coated paper, followed by immediate UV curing and subsequent finishing processes such as lamination or die-cutting.
