Aluminium Metallized Polyester Film Packaging Coated PE for Heat Sealing

Metallized PET film has a thin aluminum coating deposited onto a PET substrate, while aluminum foil is a separate metal layer. Metallized PET is generally lighter and more flexible, whereas aluminum foil can provide a stronger barrier when properly specified. The right choice depends on your application and required barrier performance.

Barrier performance depends on the PET substrate, aluminum coating quality, coating continuity, pinholes, film thickness, and any subsequent lamination or converting processes. For critical applications, WVTR and OTR should be verified using agreed test methods.

The metallized surface can reflect radiant energy and may be used as a facing in reflective insulation systems. System performance depends on surface emissivity, installation details, and the presence of an adjacent air space; the film alone does not provide a high thermal resistance.
