8079-O high-barrier aluminum foil jumbo roll

8079-O High-Barrier Foil

Premium soft temper foil with superior moisture & oxygen barrier — for demanding packaging applications

8 Series Soft Temper (O) 6–50μm Premium Grade

8079-O delivers higher tensile strength and better barrier properties than standard 8011. The alloy's optimized Fe/Si ratio reduces pinhole density, making it the go-to choice for retort pouches, aroma-sensitive food packaging, and high-end flexible laminates that demand zero-compromise barrier performance.

Typical Applications

🍲 Retort Pouches

High-temperature sterilization — ready meals, pet food, soups. Superior barrier prevents flavor loss during shelf life.

☕ Aroma Barrier Packaging

Coffee, tea, spices — products where volatile aroma compounds must be locked in. 8079's dense structure outperforms standard alloys.

🧴 Premium Cosmetic Wrappers

Facial mask sachets, cream tubes — high-end cosmetics demanding zero pinhole and pristine surface finish.

💊 High-Barrier Pharma

Moisture-sensitive strip packs and cold-form laminate foil base. Meets stringent food-grade barrier requirements.

🧈 Dairy & Fermented Foods

Butter, cheese, yogurt lids — products sensitive to oxygen ingress. Extended shelf life without preservatives.

📦 Industrial Laminates

Cable wrap, insulation facing — industrial applications requiring high tensile strength and consistent gauge uniformity.
