metaLIZED PET (VMPET) FILM — High-Barrier metallized Polyester Film

What Is metalized PET (VMPET) Film?

Metalized PET (VMPET) Film is a high-barrier polyester film produced by depositing a thin aluminum layer onto BOPET substrate through advanced vacuum metallization. The result is a film combining exceptional optical barrier performance with the mechanical strength, dimensional stability, and temperature resistance of PET.
This material is widely used in food packaging, industrial lamination, premium printing, and protective barrier applications wher high performance and durability are required.

Key Performance Advantages of VMPET Film

1. Exceptional Oxygen & Moisture Barrier

metalized PET offers one of the best barrier levels in flexible packaging:

• O₂ Transmission Rate (OTR): Extremely low

• Moisture Barrier (WVTR): Better than most other metallized films

• Effectively prevents oxidation, aroma loss, and moisture penetration

• Ideal for products requiring extended shelf stability

2. Excellent Dimensional Stability

• PET base film ensures low shrinkage and consistent thickness

• Stable performance under heat, cold storage, and mechanical stress

• Suitable for high-speed automatic packaging lines and lamination lines

3. Superior Reflectivity & Light Shielding

• Offers outstanding metallic shine and printable glossy surface

• Provides UV and visible-light blocking for light-sensitive products

• Enhances visual appeal for high-end consumer packaging

4. Mechanical Strength & Durability

• High tensile strength and puncture resistance

• Not easily deformed or stretched

• Suitable for stand-up pouches, vacuum bags, retort packaging (with multi-layer structure)

5. Versatility in Converting

• Compatible with:

  • Lamination (solvent, solventless, extrusion)

  • Printing (gravure, flexo)

  • Coating and adhesive systems

• Corona treatment available on one or two sides

• Can be combined with PE, CPP, BOPA, and aluminum foil

Applications of metalized PET (VMPET) Film

Food Packaging

• Coffee & tea packaging

• Milk powder / cocoa powder

• Snack foods, chips, nuts, dried fruit

• Spices, seasonings, powdered foods

• Pasta, rice, and cereal packaging

VMPET is a preferred material for stand-up pouches, zipper bags, and three-side seal pouches due to its excellent barrier performance.

Industrial & Protective Packaging

• Chemical powders

• Fertilizers, agricultural materials

• Industrial moisture-proof packaging

• Electronics anti-static bags (as part of multi-layer structure)

Printing & Decorative Lamination

• Silver glossy lamination film

• Gift wrapping materials

• High-quality cosmetic packaging

• Food-grade promotional packaging

Insulation & Technical Applications

• Thermal insulation materials

• Solar reflective layers

• Building insulation composites

• Energy-saving reflective sheets
