Metallized Polyethylene Terephthalate (PET) Film, commonly referred to as VMPET Film, is produced by depositing a microscopically thin aluminum layer onto polyester film through an advanced vacuum metallization process. This innovative material replicates the high-gloss metallic finish of traditional aluminum foil while offering significant advantages in weight reduction, cost efficiency, and functional performance.
Key characteristics include exceptional barrier properties against oxygen, light, and moisture, coupled with notable thermal stability and mechanical rigidity. These attributes make it ideal for demanding applications across multiple industries.
Primary applications include:
- Food Packaging: Extends shelf life for moisture-sensitive and light-degradable products such as snacks, biscuits, coffee, milk powder, and tea.
- Pharmaceutical Packaging: Ensures product integrity through superior moisture and gas barriers.
- Industrial & Specialty Uses: Functions in decorative laminates, electronic component shielding, and thermal insulation systems.
In composite flexible packaging structures, VMPET film is predominantly utilized as the intermediate layer in multilayer laminates, where it enhances structural durability while maintaining critical barrier performance.
