ALUMINIZED POLYESTER FILM — High-Barrier metallized PET Film for Packaging & Industrial Applications

What Is Aluminized Polyester Film?

Aluminized Polyester Film, commonly known as metallized PET Film (VMPET), is produced by depositing a thin, uniform layer of aluminum onto high-quality PET film through a vacuum metallization process.
This results in a film that combines:

• Exceptional gas & moisture barrier properties

• Superior dimensional stability

• High reflectivity

• Excellent mechanical strength

As one of the most advanced packaging and industrial barrier materials, aluminized PET film is widely manufactured in China, supported by large-scale production lines, precise metallization equipment, and globally certified quality standards.

Why Aluminized Polyester Film from China?

China is one of the world’s leading producers of VMPET film due to:

• Mature metallizing technology

• High-volume production capacity

• Competitive pricing

• Consistent quality control

• Strong export capability to Europe, North America, South America, Southeast Asia, and the Middle East

Tradsark is among the professional suppliers delivering international-grade aluminized PET films for packaging, insulation, and industrial applications.

Key Advantages of Aluminized Polyester Film

1. Exceptional Oxygen & Moisture Barrier

The aluminum-coated surface dramatically enhances barrier performance:

• Extremely low OTR

• Extremely low WVTR

• Excellent moisture-proof & oxygen-blocking capability

• Effective for long-shelf-life food packaging

Particularly suitable for coffee, tea, snacks, dry foods, powders, and aroma-sensitive products.

2. Superior Reflectivity & Light Shielding

The aluminum layer reflects up to 98% of radiant light and heat:

• Prevents UV exposure

• Maintains product quality and flavor

• Stable under high-temperature packaging processes

Ideal for light-sensitive products and thermal insulation applications.

3. High Tensile Strength & Dimensional Stability

PET base film provides:

• Strong mechanical strength

• High stiffness

• Excellent processability on printing and lamination machines

• Stable performance in high-speed flexible packaging lines

This makes metallized PET one of the most reliable industrial films.

4. Excellent Printability

After corona treatment, the surface offers:

• Strong ink adhesion

• Clear, vivid printing performance

• Suitable for gravure, flexo, and digital printing

Perfect for consumer packaging and premium commercial branding.

5. Versatile Lamination Compatibility

Aluminized PET can be laminated with:

• PE

• CPP

• BOPP

• Nylon (BOPA)

• Paper

• Aluminum foil

Used to build multi-layer high-barrier pouches and rolls.

6. Cost-Effective Alternative to Aluminum Foil

While providing strong barrier performance, aluminized PET film is:

• Lighter

• More flexible

• Lower cost

• Easier to process

Ideal for brands seeking high performance + cost efficiency.

Applications of Aluminized Polyester Film

1. Food & Beverage Packaging

Ideal for preserving freshness and extending shelf life:

• Coffee and tea packaging

• Milk powder and protein powder

• Candy and chocolate wrapping

• Snack and dry food packaging

• Instant soup and seasoning pouches

Barrier performance helps maintain aroma and prevent oxidation.

2. Industrial & Protective Packaging

• Insulation materials

• Cable & electronics shielding

• Reflective insulation layers

• Air duct insulation

• Automotive insulation components

metallized PET is widely used for temperature control and EMI protective systems.

3. Thermal Insulation & Reflective Applications

Due to high reflectivity, it is used in:

• Building insulation

• HVAC reflective layers

• Sunshade materials

• Emergency insulation blankets

• Radiant barrier composites

Lightweight but with excellent reflective properties.

4. Decorative & Graphic Applications

• metallic printing

• Gift wrapping

• Luxury retail packaging

• Holographic and brushed aluminum effects

Adds brightness and premium appearance.
