Advantages of Metallized PET Film / VMPET

H3: Excellent Barrier Performance

• Protects products from oxygen, moisture, and UV light, extending shelf life of food, pharmaceuticals, and chemicals.

• Provides moderate barrier properties compared to aluminum foil at a lower cost.

• Maintains product quality in long-term storage and during transportation.

Lightweight and Cost-Effective

• VMPET is significantly lighter than aluminum foil, reducing shipping costs and material usage.

• Aluminum coating uses only a fraction of the metal required for foil, lowering production costs.

• PET substrate provides strength without adding bulk.

Versatility in Processing

• Compatible with high-speed laminating, printing, and hot stamping.

• Can be combined with PE, CPP, BOPP, or other substrates for laminated packaging films.

• Available in glossy or matte finishes, enhancing visual appeal for retail packaging.

Mechanical Strength & Flexibility

• PET film base ensures high tensile strength, tear resistance, and dimensional stability.

• Flexible enough to withstand folding, bending, or heat-sealing operations without cracking.

• Suitable for complex packaging formats including pouches, sachets, and wrappers.

Printing & Branding Capability

• Corona-treated surface ensures excellent ink adhesion for flexographic, gravure, or digital printing.

• Ideal for decorative packaging, labels, and promotional films.

• Metallic gloss enhances brand perception and retail visibility.

Applications of Metallized PET Film / VMPET

Food Packaging

• Snack pouches, coffee bags, frozen food wrappers, vacuum-sealed meat, and pet food packaging.

• Barrier properties protect freshness, aroma, and taste.

• Provides metallic sheen for premium packaging appearance.

Electronics Industry

• Antistatic packaging for microchips, circuit boards, LEDs, and other sensitive components.

• Protects electronic components from electrostatic discharge (ESD) and environmental factors.

Printing & Decorative Applications

• Labels, hot stamping, and laminates for cosmetics, gift packaging, and decorative films.

• Can be used for silver and gold metallic paper applications, offering luxury aesthetics.

Pharmaceutical and Medical Packaging

• Blister packs, sachets, and sterilized medical packaging.

• High barrier ensures drug stability and moisture resistance.

Industrial and Chemical Packaging

• Packaging for pesticides, chemicals, and rescue supplies.

• Aluminum coating enhances resistance to oils, acids, and moisture.

Manufacturing Process of VMPET

Step 1 – PET Film Preparation

1. Extrusion: PET resin is melted and extruded into a thin film.

2. Biaxial Orientation: Stretching in machine and transverse directions improves tensile strength and clarity.

3. Cleaning: Dust, oil, and other contaminants removed to ensure uniform metal deposition.

Step 2 – Vacuum Metallization

1. PET film passes through a high-vacuum chamber (10⁻⁴ – 10⁻⁶ Torr).

2. Aluminum wire or pellets are evaporated under vacuum and deposited on PET film.

3. Uniform thin layer of aluminum (0.01–0.1 micron) is achieved, providing barrier and reflective properties.

Step 3 – Post-Treatment

1. Optional Coatings: Acrylic or polymer coatings improve scratch resistance, printability, and adhesion.

2. Slitting & Rewinding: Finished film is cut to custom widths and lengths.

3. Quality Inspection: Ensures barrier performance, gloss, reflectivity, and thickness uniformity.

Advantages Over Traditional Packaging Materials

VMPET combines the strength of PET with metallic barrier properties, offering a cost-effective, flexible alternative to traditional aluminum or plastic films.

Market Trends & Sustainability

Growing Demand for Flexible Packaging

• Increased demand in snacks, beverages, cosmetics, and pharmaceuticals.

• E-commerce growth drives the need for lightweight, durable, and attractive packaging.

Eco-Friendly Innovations

• Lighter films reduce carbon footprint during transport.

• Aluminum layer can be recycled, though specialized facilities may be required.

• Supports sustainable packaging initiatives by minimizing material usage.

Technological Advancements

• Development of ultra-thin aluminum layers reduces material usage without sacrificing barrier performance.

• Advanced corona and surface treatments improve lamination, printing, and heat seal properties.

• Integration of smart packaging features such as QR codes, RFID, and anti-counterfeit printing.

How to Choose the Right Metallized PET Film / VMPET

1. Barrier Requirements: Choose appropriate aluminum thickness for oxygen/moisture protection.

2. Film Thickness: 6–125 micron based on application; thicker films for industrial use, thinner for retail packaging.

3. Surface Finish: Glossy or matte for aesthetic purposes.

4. Lamination Compatibility: Ensure compatibility with PE, CPP, BOPP, or other substrates.

5. Regulatory Compliance: Food-grade, medical-grade, or industrial-grade certifications as required.
