Water-Based Varnishes: High-Performance Protection and Finish

Flexographic overprint varnishes are advanced, solvent-free liquid coatings. They are designed to be applied over printed surfaces with a dual objective: protecting the substrate and enhancing the final aesthetic finish, significantly improving the product's overall durability.

This process integrates seamlessly into production lines using industrial flexographic presses. Through the use of flexible photopolymer plates, we achieve optimal transfer and high-quality, uniform coverage across multiple substrates, including paper, paperboard, and plastic films.

Technical and Environmental Advantages

• Maximum Sustainability: Their water-based formulation drastically reduces VOC (Volatile Organic Compound) emissions, facilitating compliance with strict environmental regulations and driving cleaner, greener production.
• Functional Barrier: Performance is never compromised. They act as a highly effective technical shield against moisture, scratching, and scuffing during transport and handling.
• Custom Finishes: They add significant value to the final design, allowing for the application of gloss, matte, or textured effects tailored to your specific requirements.

Industrial Application: Our water-based varnishes are an essential component in ensuring maximum quality and resistance in the packaging industry, label manufacturing, and highly demanding graphic products.

Water-Based Flexographic Inks: Performance, Color, and Sustainability

Our range of water-based flexographic inks is formulated to deliver superior performance in highly demanding industrial printing environments. Designed to maximize productivity on flexo lines and minimize environmental impact, these solvent-free inks provide exceptional color transfer, excellent dot definition, and highly efficient drying.

They are specially developed for converters and printers seeking to combine premium shelf appeal with agile, eco-friendly operations, adapting perfectly to multiple cellulosic substrates.

Technical and Operational Advantages

• High Pigmentation & Color Strength: Concentrated formulations that guarantee intense, dense, and vibrant colors. This optimizes ink consumption per square meter, effectively reducing operational costs without sacrificing visual impact.
• Press Stability (Runability): Engineered with excellent rheological behavior that maintains stable viscosity during long print runs. They prevent premature drying on the plate or in the anilox roller, ensuring fast start-ups and drastically reducing substrate waste.
• Productivity & Fast Drying: Optimized to withstand high printing speeds. They facilitate ultra-fast drying on the substrate, avoiding offsetting issues and allowing for immediate in-line converting or die-cutting processes.
• Sustainability & Safety: 100% water-based solutions with virtually zero VOC (Volatile Organic Compound) emissions. Ideal for companies focused on the circular economy and compliance with the strictest industrial health and safety regulations.

Industrial Application: Hynsel's water-based flexographic inks are the optimal choice for high-volume printing on corrugated board, folding cartons, paper sacks, bags, napkins, and sustainable packaging solutions.

Flexographic Functional Barriers: Advanced Protection & Food Safety

Functional barriers are high-performance technical coatings engineered for flexographic application across a wide range of substrates. Their advanced formulation forms a continuous protective shield against external agents, preserving product integrity, extending shelf life, and ensuring full compliance with international food contact regulations.

Heat-Sealable Coatings: Solutions for Secure and Efficient Sealing in Flexography

Heat-sealable coatings are advanced functional solutions designed to create a reliable thermal sealing layer on flexible packaging and laminated structures. Applied directly via flexography onto paper, cardboard, or film substrates, these coatings eliminate the need for additional structural layers. This streamlines production processes and optimizes operational costs while ensuring maximum airtightness, protection, and safety, particularly in stringent food contact applications.

Operational Advantages on Press

• High-speed inline processability: Formulated for high-speed flexographic printing, integrating seamlessly into the printing workflow without requiring extra lamination steps.
• Reliable thermal sealing: Facilitates quick and secure packaging closure through heat and pressure, ensuring absolute airtightness and prolonged product protection.
• Sustainability and eco-design: Promotes the development of mono-material packaging and reduces the reliance on complex laminations, significantly improving the end-product's recyclability.

Flexo Primers: Advanced Surface Preparation for High-Quality Printing

Flexographic primers act as a high-performance preparatory coating on substrates such as paper, kraft, and recycled cardboard. They function as a leveling intermediate layer that uniformizes surface porosity, guaranteeing flawless ink transfer and optimal performance of the final packaging, maintaining its structural integrity even in demanding environments such as cold chains.

Machine Operational Advantages

• Dimensional Stability: Drastically reduces moisture absorption, preventing substrate deformations, curling, and warping.
• Excellent Anchorage & Printability: Enhances the transfer of inks and varnishes, achieving more vibrant colors, high definition, and outstanding rub resistance.
• Homogeneous Surface: Corrects the natural porosity of the material and prevents critical printing defects such as mottle.
• Post-Process Compatibility: Ensures perfect adhesion in subsequent automatic processes like lamination, die-cutting, varnishing, and gluing.

Flexo Concentrated Bases: Maximum Consistency for Color Kitchens

Concentrated bases are high-load pigmentary premixes specifically designed for use in industrial mixers or color kitchens. They form the chromatic and functional core of ink formulations, allowing the development of Ready to Use (RTU) systems through the addition of extenders and additives. Available in water-based technology, they guarantee excellent compatibility and superior performance on paper, corrugated board, plastic films, engineered wood, and metallized substrates, making them ideal for flexography, gravure, screen printing, and food packaging.

Operational Advantages on Press

• Color consistency and repeatability: High pigment concentration and strict L*a*b* balance control ensure stable batches and precise corrections, which are vital for critical color projects.
• Maximum operational efficiency: Significant reduction in formulation times and inline color changeovers, drastically lowering the inventory volume of finished inks.
• Multi-technology modular flexibility: Allows blending of basic and special colors to cover standard ranges, Pantone® colors, and GCMI certifications, adapting seamlessly to water-based processes, functional varnishes, and primers.
• Production cost optimization: Exact dosing of pigments and resins, promoting the rational use of extenders (white/transparent) and additives based on specific coverage and viscosity requirements.
