Pre-Mixed Solvent for Printing Ink on PE Film

Pre-mixed solvent for printing ink on PE film is an optimal solution to improve printing efficiency on flexible plastic surfaces like Polyethylene (PE). With a specialized formula developed by K-Chem, this product not only ensures strong ink adhesion and fast drying but also maintains the sharpness and color durability of the printed image. In this article, K-Chem will help you explore the concept, outstanding features, and effective usage of this solvent line.

What is Pre-Mixed Solvent for Printing Ink on PE Film?

Solvent for PE (Polyethylene) film ink is a pre-prepared liquid mixture used to dissolve ink, adjust viscosity, and enhance adhesion on PE film surfaces. PE film is known for its smooth and non-porous nature, making it difficult for ink to adhere. Therefore, the solvent must support strong ink adhesion, quick drying, and high-quality print output without damaging the film.

Outstanding Advantages of K-Chem’s PE Ink Solvent Formula

K-Chem’s pre-mixed solvent for printing ink on PE film is developed based on a specialized formula tailored for plastic materials with smooth surfaces and low ink adhesion like Polyethylene (PE), offering the following advantages:

Superior Adhesion

K-Chem’s PE ink solvent enhances the adhesion of the ink, ensuring uniform color distribution and preventing peeling during lamination or bending.

Effective Dissolution

The PE ink solvent formula is designed to thoroughly dissolve gravure and Flexo inks, resulting in a homogeneous ink mixture with no layer separation or clumping. This minimizes defects and maintains consistent print quality.

Ideal Drying Time

K-Chem’s PE ink solvent features an optimally balanced evaporation rate—fast enough to support high-speed printing systems but not so fast that it causes drying at the roller head or nozzle clogging. This helps maintain production pace without reducing the lifespan of printing equipment.

Compatibility with PE

The solvent does not cause PE film to shrink, deform, or lose transparency. Its chemical compatibility preserves the mechanical structure and durability of the material after printing.

Easy Viscosity Adjustment

K-Chem’s PE ink solvent allows flexible viscosity adjustment to suit different machines and specific applications, enabling smooth ink flow and even coating without screen or roller clogging, resulting in sharp, uniform prints.

Safe and Low-Toxic

K-Chem’s PE ink solvent is designed to reduce harmful emissions, ensuring operator and environmental safety, and complies with modern occupational safety standards.

Main Components Commonly Found in Pre-Mixed Solvents for Printing Ink on PE Film by K-Chem

For Gravure Printing Technology: Organic solvents such as Toluene (optional), MEK, EA, IPA, DMC,… are used in optimal ratios to ensure good ink adhesion and sharp image display on PE film.

For Solvent-Based Flexo Printing Technology: Organic solvents such as NPAC, NPA, Ethanol,… are used in optimal ratios to ensure good ink adhesion and sharp image display on PE film, while avoiding damage to the Anilox roller and printing plate.

Instructions for Using K-Chem PE Film Ink Solvent

Check Compatibility

Before mass production, ensure the pre-mixed solvent is compatible with the type of ink (Gravure or Flexo) and PE film.

Mixing Ink with Solvent

Determine the required amount of ink and add solvent according to the recommended ratio (usually 15 – 20% of the ink volume). Use a stirrer or mix manually for 5 – 10 minutes until the solvent is fully blended. This helps prevent ink separation or foaming. Use a viscosity cup to check the viscosity.

Test Print and Quality Check

Conduct a test print on PE film to check ink adhesion and print quality before proceeding to mass printing.

Official Printing Use

Transfer the mixed ink into the printer’s ink feed system. Wear chemical-resistant gloves, safety goggles, a mask or organic vapor respirator, and work in a well-ventilated area to minimize prolonged exposure to solvent fumes.

Post-Printing Equipment Cleaning

Immediately after printing, clean the printing roller, ink cup, ink brush, and any equipment that came into contact with ink using specialized cleaning solvents. Avoid letting ink dry and harden on equipment, as this can make future use difficult and affect print quality.

Storage Guidelines for K-Chem PE Film Ink Solvent

Store in a Dry, Cool Place

Store K-Chem PE film ink solvent in a dry, cool area at temperatures below 30°C, away from moisture.

Avoid Direct Sunlight and Heat Sources

Keep away from direct sunlight and heat sources such as stoves or heat-emitting machinery, as these can cause rapid evaporation or alter the solvent composition.

Seal Tightly to Prevent Evaporation

After each use, tightly seal the container or drum to limit air exposure and contamination.

Avoid Fire Sources

K-Chem PE film ink solvent is flammable. Keep away from sparks, cigarettes, or heat sources. Post warning signs in areas where the solvent is stored.

Use Protective Equipment

Work in an environment with ventilation or local exhaust systems to reduce solvent vapor concentration in the air. Wear gloves, a mask, and safety goggles to avoid direct contact with skin.

Check Expiry Date

Before use, check the expiry date on the packaging. Expired solvent may lose stability, affecting ink solubility, viscosity, or drying time.

Keep Out of Reach of Children

Store K-Chem PE film ink solvent in a designated chemical storage area, placed out of children’s reach and avoid direct contact with skin and eyes.
