Why Choose Fresherpack 8 Mil Extra Heavy Duty Foil Bags?
-
Thickest 8 Mil (204µm) Construction
While standard foil bags are usually around 3.5 Mil, our extra heavy-duty bags feature an unmatched 8 Mil (204µm) single-wall gauge. With both sides combined, you get an impressive 16 Mil (408µm) total thickness for maximum physical toughness and puncture resistance.
-
Real Pure Aluminium Layer
Built with a real layer of continuous aluminium foil rather than cheap spray-on metallised coating. This guarantees 100% lightproof and UV-resistant protection without the risk of micro-pinholes.
-
100% Smellproof & Moistureproof Barrier
Once heat-sealed, internal smells cannot escape and external room humidity or ground moisture cannot enter, providing an airtight environment to preserve food staples, seeds, or precious archival items like photos, comics, and vinyl albums.
-
Boil-in-Bag & Freezer Proof
Engineered using special heat-resistant adhesives—safe for deep freezing down to -60°C and boil-in-the-bag cooking applications up to 100°C for up to 30 minutes.
-
Easy Heat Sealing & Hand Opening
Seals easily using a household clothes iron (high setting, no steam) or hair straightener. Includes a pre-cut side tear notch above the seal for quick hand-opening when needed.
