In the U.S. flexible packaging and laminating industries, copolymer coated pet film USA has become a go-to solution for applications requiring strong adhesion and secure sealing. By applying a copolymer layer to standard PET film, converters gain enhanced bonding strength that improves performance in multilayer laminates and heat-sealable packaging structures.
At Pilcher Hamilton Corporation, based in Greer, SC, we supply and convert copolymer coated polyester films for U.S. packagers, laminators, and converters. This guide explores how these films work, their applications, and practical tips for lamination and sealing in the USA.
What Is Copolymer Coated PET Film?
A copolymer coating is applied to polyester film to improve adhesion to other substrates such as polyethylene (PE), polypropylene (PP), aluminum foil, and paper. This coating ensures strong lamination bonds and reliable sealing during packaging.
Why It Matters for the U.S. Market
- Stronger Lamination Bonds: Reduces delamination issues in multilayer structures.
- Heat Sealing Performance: Enables flexible packaging pouches, sachets, and lidding with improved seal integrity.
- FDA Compliance: Suitable for food contact packaging in the USA.
- Efficiency: Enhances production yields for converters and laminators.
Lamination Tips for U.S. Converters
- Surface Treatment: Ensure corona or chemical treatment before laminating for maximum adhesion.
- Adhesive Selection: Use adhesives compatible with copolymer-coated surfaces for consistent bond strength.
- Tension Control: Maintain balanced web tension to avoid wrinkles and misalignment.
- Curing Conditions: Allow proper curing time for adhesives to achieve full bond performance.
Sealing Tips for U.S. Packaging
- Temperature Range: Optimize sealing temperatures to activate the copolymer layer without damaging substrates.
- Pressure & Dwell Time: Apply uniform pressure and adequate dwell time for consistent seal integrity.
- Testing: Conduct peel and burst testing to confirm seal strength under U.S. food and industrial packaging standards.
Applications in the USA
- Food & Beverage Pouches: Coffee, snacks, and frozen goods.
- Medical & Pharmaceutical Packaging: Sterile pouches and laminates.
- Industrial Packaging: Chemical products requiring leak-proof sealing.
- Specialty Laminates: Paper-film or foil-film combinations for high-performance packaging.
