Printed PET Films: Ink, COF & Registration Control USA
In the U.S. converting and packaging industries, printed polyester film USA is essential for applications where high-quality graphics, durability, and precise converting performance are required. PET’s strength, clarity, and tunable surface properties make it one of the most reliable substrates for printing — whether for food packaging, labels, or industrial graphics.
At Pilcher Hamilton Corporation, headquartered in Greer, SC, we supply and convert printed PET films for U.S. converters and brand owners. This guide explores the key considerations for ink adhesion, coefficient of friction (COF), and registration control in printed polyester film applications.
Why Choose Printed PET Film in the USA?
- Durability: PET films resist tearing, abrasion, and humidity during distribution.
- Clarity: High optical properties showcase graphics with vibrant colors.
- Flexibility: Compatible with gravure, flexo, UV, and digital printing processes.
- Regulatory Compliance: FDA-approved options available for U.S. food and pharma packaging.
Ink Adhesion on PET Films
Ink adhesion is one of the most critical performance factors. Standard PET surfaces are inert and require surface treatment (typically corona or chemical coating) to achieve proper ink wetting.
Tips for U.S. Printers
- Use corona treated PET films for consistent ink adhesion.
- Test ink compatibility (solvent, UV, or water-based) with the film surface.
- Conduct adhesion tests before high-speed production runs.
COF (Coefficient of Friction) Considerations
The coefficient of friction (COF) impacts machine handling during high-speed converting.
- Low COF films: Ensure smooth transport through presses and laminators.
- High COF films: Provide stability where slip-resistance is required.
Pilcher Hamilton offers custom COF tuning to match U.S. printing and converting line requirements.
Registration Control in Printed PET
Registration accuracy ensures that graphics align properly during multi-color or multi-pass printing. Polyester films provide excellent dimensional stability, reducing distortion during press runs.
Best Practices for U.S. Converters
- Maintain precise web tension control.
- Store films in controlled environments to prevent moisture expansion.
- Use dimensionally stable PET films for tight registration tolerances.
Applications of Printed Polyester Film in the USA
- Food Packaging: Snack wraps, frozen food pouches, and lidding films.
- Labels & Sleeves: High-clarity graphics for retail branding.
- Industrial Graphics: Durable overlays and printed industrial films.
- Promotional Displays: Sharp, high-impact graphics for U.S. marketing campaigns.
