PET Coated Aluminum Foil Roll

PET coated aluminum foil roll is produced by coating an extremely thin layer (1–5 μm) of polyester (PET) resin onto the surface of aluminum foil.

While retaining the aluminum foil's high barrier properties and flexibility, it additionally gains characteristics such as chemical corrosion resistance, electrical insulation, and heat resistance.

It is mainly used in electromagnetic shielding, heating elements, chemical packaging, and specialized industrial fields, rather than in ordinary food flexible packaging.

The applications of PET coated aluminum foil roll are primarily in industrial, electronic, and specialty packaging, not in general food flexible packaging.

1. Electronics & Electrical

• Electromagnetic Shielding Materials: Used as cable shielding layers and internal shielding films for electronic devices. The PET coating provides insulation, while the aluminum foil offers conductivity and shielding.
• Flat Flexible Cable (FFC) Shielding: Used in internal connecting cables for printers, scanners, and LCD televisions.
• Pressure-Sensitive Aluminum Foil Tape: The PET coating acts as a release layer or reinforcement layer, used for fixing electronic components and transformer shielding.

2. Corrosion-Resistant Packaging

• Chemical Product Packaging: For packaging corrosive powders and liquids (e.g., pesticides, dyes). The PET coating prevents the aluminum foil from being corroded by the contents.
• Pharmaceutical Packaging (select applications): For pharmaceutical products requiring extremely high chemical stability, preventing direct contact and reaction between the drug and the aluminum foil.

3. Heating Elements

• Electric blankets, car seat heaters: The PET coating provides electrical insulation, while the aluminum foil serves as the conductive heating layer (etched circuit).

4. Construction & Automotive

• Insulation Material Facings: Laminated with fiberglass cloth for pipe and duct insulation. The PET coating enhances aging resistance and waterproof performance.
• Automotive Heat Shields: Used near engine compartments and exhaust pipes. The PET coating is heat-resistant and prevents oxidation of the aluminum foil.

5. Specialty Packaging

• Anti-Static Packaging: Antistatic agents can be added to the PET coating, used in anti-static bags for electronic components and precision instruments.
• High-Barrier Laminated Tubes: Inner coating for toothpaste and cosmetic tubes, preventing reaction between the paste and the aluminum foil while providing better chemical resistance.

Technical Support

• Coating Selection: Recommend appropriate coating thickness and formulation based on temperature resistance requirements (≤200°C), insulation grade, and lamination process.
• Process Guidance: Resolve issues such as coating cracking, poor adhesion, and heat seal blistering.
• Application Adaptation: Provide specialized recommendations for HVAC ducts, electronic shielding, and food laminated packaging.
