What is Metalized PET Film Coated PE?

Core Definition

Metalized PET Film Coated PE consists of a thin VMPET layer (typically 6–12 microns) vacuum-coated with an ultra-thin aluminum layer, laminated with a polyethylene (PE) layer (2–15 microns). The combination delivers:

1. High reflectivity for solar heat and light.

2. Waterproof and damp-proof characteristics.

3. Flexibility for lamination with foam insulation materials.

Material Composition

• Base Layer: PET metallized with aluminum, providing reflective properties and barrier resistance.

• PE Coating: Enhances waterproofing, mechanical protection, and lamination compatibility.

• Thickness Variations: Customizable to meet diverse thermal insulation requirements.

Specifications

Key Performance Metrics

• Floor insulation: Prevents cold conduction and improves indoor comfort.

Foam Lamination

• Laminates with EPE, XPE, or bubble foam for packaging or building applications.

• Ideal for producing reflective insulation blankets, panels, and sheets.

Packaging and Industrial Protection

• Protects sensitive electronic equipment from heat and moisture.

• Used in thermal packaging for food, pharmaceuticals, or chemicals.

HVAC and Duct Insulation

• Prevents heat loss in air ducts and ventilation systems.

• Reduces condensation and improves HVAC system efficiency.

Technical Advantages

High Reflectivity

• Reflects up to 95% of solar radiation.

• Reduces indoor temperature by 5–10°C in summer roof applications.

Thermal Conductivity

• Low thermal conductivity enhances insulation performance.

• Works efficiently with foam materials to create multi-layered thermal barriers.

Moisture Barrier

• PE layer forms a tight barrier to prevent water vapor penetration.

• Reduces risk of mold, mildew, and insulation degradation.

Mechanical Strength

• Metallized PET layer provides high tensile strength.

• PE coating adds flexibility and tear resistance.

• Resistant to punctures, folds, and repeated handling.

Installation Guidelines

1. Surface Preparation: Ensure substrate or foam surface is clean and smooth.

2. Film Orientation: Place metallized side outward for reflective performance.

3. Lamination: Use adhesive or thermal lamination to bond with foam layers.

4. Fixing and Sealing: Seal edges with tape or heat sealing for maximum moisture protection.

5. Maintenance: Periodically inspect for damages; minor tears can be repaired with reflective tape.
