Improving printing on PET foils using plasma surface
treatment.
PET (polyethylene terephthalate) foils are utilized across various
industries due to their strength, transparency, chemical resistance,
and barrier properties.
PET foils are chosen for their versatility, recyclability, and
performance in demanding environments, making them integral
to both everyday and specialized applications.
Here's a structured overview of their applications where printing
is commonly necessary:
1. Packaging:
Food Packaging: Used for snack bags, wrappers, and metallized films to provide moisture,
oxygen, and aroma barriers.
Pharmaceuticals: Blister packs and sterile packaging for moisture and contamination
protection.
2. Electronics:
Insulation: Protective layers in cables, capacitors (as dielectric films), and flexible printed
circuits.
3. Printing & Labels:
Durable Labels: For products, electronics, and machinery due to tear resistance.
Lamination: Protective coatings for documents, ID cards, and credit cards.
Graphic Arts: Banners, decals, and holograms leveraging PET's printability and durability.
4. Automotive:
Protective Films: Paint protection and interior decorative foils.
5. Medical:
Sterile Packaging: Ensures safety and longevity of medical devices.
6. Industrial:
Release Liners: For adhesives and composites..
7. Textiles:
Laminated Fabrics: Waterproof and weather-resistant materials for outdoor gear.
8. Specialty Applications:
3D Printing: Substrates or support materials.
Arts & Crafts: Stencils and transparent overlays.
Printing on PET can be tricky because of its low surface energy. To enhance printing quality on PET foils
using plasma surface treatment, follow this structured approach tailored to optimize ink adhesion and print
durability:
1. Plasma Type and Gas Selection
• Oxygen Plasma:
Introduces polar functional groups (-OH, -COOH) to increase surface energy, improving
Wettability for inks.
Ideal for water-based and solvent-based inks.
• Nitrogen or Argon Plasma:
Enhances cross-linking or creates mild etching for mechanical interlocking (useful for UV
curable inks).
• Gas Mixtures (e.g., O2 + Ar):
Combines chemical activation (polar groups) with controlled physical etching for tailored
surface roughness.
2. Key Parameters Optimization
• Power: Lower power for atmospheric plasma to avoid overheating; higher power in vacuum
systems.
• Treatment Time: Shorter times for atmospheric plasma to maintain production speed.
• Pressure:
Vacuum systems: 0.1-1 mbar for uniform treatment.
Atmospheric systems: Ambient pressure for inline processing.
• Distance: Based on plasma source and PET surface (adjust for uniformity and heat management).
3. Equipment Considerations
• Atmospheric Plasma:
Best for high-speed, roll-to-roll printing lines (e.g., packaging or label production).
• Low-Pressure Plasma:o Suitable for precision applications (e.g., electronics or medical packaging) with controlled
treatment depth.
• Plasma Jet Arrays:
Ensures uniform treatment across wide PET foils.
4. Surface Activation
• Chemical Modification:
Polar groups increase surface energy (measured via contact angle < 40° for water),
enabling better ink spreading and adhesion.
• Physical Etching:
Nano-scale roughness (observed via AFM) creates anchoring points for ink particles.
• Cleaning:
Removes contaminants (e.g., oils, additives) that hinder ink bonding.
5. Post-Treatment Handling
• Immediate Printing: Apply ink within 15-60 minutes post-treatment to avoid surface aging
(hydrophobic recovery).
• Storage: If delayed, store treated PET in dry, inert environments (e.g., nitrogen) to preserve surface
activation.
• Primers: Use adhesion promoters (e.g., silanes) for long-term stability in harsh conditions.
6. Characterization and Validation
• Contact Angle Measurement: Confirm hydrophilicity (target water contact angle < 40°).
• Ink Adhesion Tests:
Tape Test (ASTM D3359): Assess ink peel resistance.
Abrasion Resistance: Rub tests (e.g., Sutherland Rub Tester) for durability.
• Surface Analysis:
XPS/FTIR: Verify oxygen-rich functional groups.
AFM: Quantify surface roughness (Ra ~10-50 nm ideal for ink anchoring).
7. Industrial Implementation Tips
• Uniformity: Use rotating electrodes or multi-jet systems for consistent treatment in roll-to-roll
setups (see Keylink Technology Plasma Systems).
• Ink Compatibility:
Hydrophilic surfaces for water-based inks.
Moderate roughness for solvent-based or UV-curable inks.
• Pre-Treatment Cleaning: Remove dust and static with ionized air or mild solvents (e.g.,
isopropyl alcohol).
8. Troubleshooting Common Issues
• Poor Ink Adhesion:
Increase plasma power/time or switch to oxygen plasma.
Check for contaminants or insufficient surface activation.
• Over-Treatment:
Reduce power/time if the PET becomes brittle or discolored.
• Ink Spreading Issues:
Optimize surface energy (contact angle) for ink viscosity.
By optimizing plasma parameters and process integration, you can achieve vibrant, durable prints on PET
foils while maintaining production efficiency.
For precise metrics, collaborate with Keylink Technology to test your material under controlled conditions.
