Non-porous ink is specifically designed to adhere to smooth, non-absorbent surfaces such as plastic, glass, metal, and coated paper. When printing on plastic pouches, especially those used for packaging liquids like 1 liter pouches, it’s crucial to use ink that will dry quickly and form a permanent bond with the surface to prevent smudging, smearing, or fading.

Here are some considerations when selecting non-porous ink for printing on plastic pouches:

1. Compatibility with Plastic: Ensure that the ink is compatible with the type of plastic used for your pouches. Different plastics may require different ink formulations to ensure proper adhesion and durability. Common types of plastic used for pouches include polyethylene (PE), polypropylene (PP), and polyester (PET).
2. Fast Drying: Look for ink that dries quickly on non-porous surfaces to minimize the risk of smudging or smearing during handling and transportation. Fast-drying ink helps maintain print quality and readability, especially on high-speed production lines.
3. Waterproof and Fade-Resistant: Choose ink that is waterproof and resistant to fading, as plastic pouches may come into contact with moisture or undergo exposure to sunlight during storage or transportation. Waterproof and fade-resistant ink ensures that the printed information remains legible and intact throughout the product’s lifecycle.
4. Chemical Resistance: Consider the resistance of the ink to chemicals commonly found in the contents of the plastic pouches, such as cleaning agents, oils, or solvents. Chemical-resistant ink prevents the printed information from smudging or dissolving when exposed to these substances.
5. Opaque and Vibrant Color: Select ink that provides opaque and vibrant color coverage for clear and legible printing on dark or colored plastic pouches. Opaque ink ensures that the printed information stands out against the background for easy readability.
6. Adhesion Promoters: Some non-porous surfaces may require the use of adhesion promoters or primers to enhance ink adhesion and durability. Consider whether your plastic pouch material requires any pre-treatment or surface preparation to ensure proper ink adhesion.
7. Food-Grade Certification: If the plastic pouches are used for packaging food or beverages, ensure that the ink is certified as food-grade and compliant with relevant regulations and standards for food contact materials.
8. Manufacturer Reputation and Support: Choose ink from a reputable manufacturer with a track record of producing high-quality, reliable products. Ensure that the manufacturer provides comprehensive technical support, product documentation, and after-sales service to address any issues or inquiries.

By considering these factors, you can select non-porous ink that meets your specific requirements for printing on plastic pouches, ensuring durable, legible, and professional-looking prints for your packaging needs.
