Pure Aluminum Foil (AL 7μm/9μm) vs Metallized VMPET vs Transparent AlOx / SiOx Barrier Films
Selecting the wrong middle barrier layer either over-engineers your BOM by 28% or causes premature rancidity and vitamin oxidation. Solid 7μm–9μm AA8079 Pure Aluminum Foil (AL) provides near-zero gas permeation (OTR ≤ 0.03 cc, WVTR ≤ 0.04 g, 100% UV block) required for 24-month shelf-life coffee, retort pouches, and acidic cosmetic serums. Vacuum-Metallized PET (VMPET 12μm) uses a 400 Å vapor-deposited aluminum coat to deliver OTR ≤ 0.80 cc at 22% lower cost and superior flex-crack resistance for dry snacks. Transparent AlOx/SiOx-PET offers OTR ≤ 0.45 cc with clear product windows and metal-detector/microwave compatibility.
"Buyers frequently refer to both VMPET and pure Aluminum as 'foil pouches', yet physically they are worlds apart: VMPET is a 12μm polyester film misted with a 0.04μm atomic layer of aluminum (hold it up to a strong LED flashlight and you can see light through it), whereas AL7/AL9 is a solid rolled metal sheet of AA8079 alloy that blocks 100.0% of oxygen, moisture, and UV photons."
