🛡️ 5.1 Mil Heavy Duty Thickness

☀️ 100% Light & UV Block

🧪 BPA-Free / Food Grade Certified

Our premium 5.1 mil (130 micron) Mylar foil bags offer exceptional long-term protection for small-batch storage. With a genuine aluminium foil layer (not cheap metallised film), these heavy-duty bags provide superior lightproof, smellproof, moistureproof, and oxygen-barrier performance.

Perfect for:

Long-term food storage (rice, beans, pulses, flour, sugar, seeds, hops, spices, etc.)
Herbs, botanicals, and supplements
Precious items such as photos, documents, comics, vinyl, jewellery, and more

Key Features & Benefits

Extra Thick – 5.1 mil (130 micron) per side → 10.2 mil total when sealed for maximum durability and protection
Real Aluminium Foil Layer – True lightproof barrier (unlike thin metallised films that develop pinholes)
Smellproof & Moistureproof – Excellent odour and humidity control once heat-sealed
Food-Grade & BPA-Free – Safe for direct food contact
Boil-in-Bag & Freezer Proof – Withstands boiling up to 30 minutes and temperatures down to -60°C
Tear Notch – Easy hand-opening after sealing
Heat Sealable – Quickly seal using a household iron (high heat, no steam) or hair straightener

Dimensions: 70mm x 100mm (opens on the short side)

These compact bags are ideal for portion control, sample storage, emergency kits, camping meals, or protecting small valuables.

Recommended Use: Pair with our 20cc Oxygen Absorbers (one per bag) for ultra-long-term food storage up to 20+ years.
