Pre-Mixed Solvent for Printing Ink on PET Film

PET film ink solvent is becoming a modern and convenient printing solution, optimizing efficiency in the packaging, labeling, and industrial printing industries. K-Chem’s ready-to-use solvent formula for PET film printing ink stands out for its ability to control evaporation rate, maintain print sharpness, and suit various solvent-based inks. The following article will guide you through the product’s superior features, main components, and proper usage to achieve optimal print quality. Read on!

What is Ready-to-Use Solvent for PET Film Printing Ink?

Ready-to-use solvent for PET film printing ink is a liquid used to dissolve, adjust viscosity, and improve ink adhesion on the surface of PET (Polyethylene Terephthalate) film. These solvents help ink adhere evenly, dry quickly, and produce sharp, long-lasting prints.

Outstanding Features of K-Chem’s Ready-to-Use PET Film Ink Solvent

K-Chem’s ready-to-use PET film ink solvent is developed based on the characteristics of PET, a smooth, ink-resistant surface that still demands high print sharpness in industrial printing. Thanks to its optimized formula, this product offers several key advantages:

Superior Solubility

K-Chem’s PET film ink solvent uses a high-dispersion solvent system that fully dissolves ink particles without precipitation. When used in high-speed printing systems, it prevents clumping, clogging of nozzles, or blockage of ink lines.

Effective Viscosity Control

Viscosity is a critical factor affecting ink smoothness, sharpness, and adhesion. K-Chem’s formula allows optimal viscosity adjustment, ensuring ink is neither too thin (causing smudging) nor too thick (causing clogs). Ink flows evenly over the PET surface, capturing every detail sharply.

Optimized Evaporation Rate

K-Chem’s PET film ink solvent has a moderate drying speed fast enough to prevent smudging, but slow enough to avoid printhead drying, thus preserving fine detail and preventing back transfer (blocking).

High Adhesion

K-Chem includes adhesion-enhancing additives that help ink stick firmly to the PET surface, even under stretching, bending, or friction. This ensures long-lasting prints that retain color and resist peeling during use or packaging.

PET Compatibility

Unlike harsh solvents that can roughen or corrode PET film, K-Chem’s solvent formula has been tested for high safety, preserving the film’s transparency, gloss, and mechanical durability.

Safe and Environmentally Friendly

K-Chem’s ready-to-use PET film ink solvent contains low-toxic organic components with mild odor and biodegradable properties. Reduced VOC (volatile organic compound) content minimizes harm to operators and improves workplace safety in printing facilities.

Main Ingredients in K-Chem’s PET Film Ink Solvent

For Gravure Printing Technology: Organic solvents such as Toluene (with or without), MEK, EA, IPA, DMC,… in optimized ratios to ensure ink adhesion and sharp image rendering on PET film.

For Flexo Printing (solvent-based): Organic solvents such as NPAC, NPA, Ethanol,… in optimized ratios to ensure ink adhesion and clear image rendering on PET film, without damaging the Anilox roller or printing plate.

How to Use K-Chem’s Ready-to-Use PET Film Ink Solvent

Check Ink and Solvent Compatibility

Before mixing, identify the ink type to ensure the solvent is compatible (gravure, flexo).

Proper Mixing Ratio and Technique

Measure the required ink amount and add solvent at the recommended ratio (typically 15 – 25% solvent to ink). Stir thoroughly using a magnetic stirrer or manually for 3 – 5 minutes to achieve complete mixing and avoid layer separation. Check viscosity using a viscosity cup.

Test Before Mass Printing

Print a sample on PET film to check ink adhesion, drying speed, and resistance to smudging. Ensure the solvent does not cause clouding, wrinkling, or resin melting when the PET is stretched.

Proceed to Production Printing

Apply the mixed ink onto the printer, ensuring correct settings for printhead, pressure, and speed according to the current viscosity. Work in a well-ventilated area to prevent accumulation of flammable solvent vapors, and use proper protective gear.

Print Quality Check

Ensure solvent-ink compatibility during high-volume printing. Ink should maintain sharpness and strong adhesion.

Post-Use Cleaning

Thoroughly clean the printing system, ink tanks, ink pipes, and printhead using a specialized cleaning solvent to remove any remaining ink. Avoid dried ink in the machine as it can clog components and reduce equipment lifespan. Store leftover solvent in a sealed container in a cool, ventilated area to preserve quality.

Storage Guidelines for K-Chem’s Ready-to-Use PET Film Ink Solvent

Store in a dry, cool, and well-ventilated place

Keep the solvent and printing ink in a dry, well-ventilated area with stable temperatures between 15 – 30°C. Avoid direct sunlight and high heat to maintain product quality.

Seal the container tightly after each use

Always tighten the cap of the solvent can or container after use to prevent rapid evaporation or contamination from environmental impurities (dust, moisture, humid air). Contaminated solvent can alter ink properties, causing precipitation, sedimentation, or reduced adhesion.

Keep out of reach of children

Store in a safe place, never leave the solvent in low or easily accessible areas for children. Attach warning labels and avoid direct contact with skin or eyes.

Check the expiration date

Do not use expired solvent as it may reduce mixing effectiveness and print quality. If there are signs of discoloration, sediment, or unusual odor, stop using the product immediately and contact the supplier for guidance.

Ensure workplace safety

Use proper ventilation systems or install fume extraction and odor filtration systems in the printing area. Always wear chemical-resistant gloves, protective goggles, and specialized masks when handling the solvent for extended periods.
