Why Choose Fresherpack Premium Mylar Foil Bags?

  • Thicker Than Standard Alternatives

    Featuring an impressive 5.1 Mil (131Āµm) single-wall thickness (10.2 Mil total when sealed), providing vastly superior physical strength and puncture resistance compared to thin 3.5 Mil market alternatives.

  • Real Pure Aluminum Core Layer

    Contains a continuous layer of aluminum foil rather than cheap spray-on metallized coating, ensuring zero pinholes and complete barrier protection against light, UV, moisture, and oxygen.

  • 100% Smellproof & Moistureproof Barrier

    Once heat-sealed, internal aromas cannot escape and external ambient moisture cannot enter, keeping delicate contents fresh and dry for up to 10 years when combined with an oxygen absorber.

  • Boil-in-Bag & Extreme Temperature Rated

    Engineered with specialized heat-resistant adhesivesā€”safe for deep freezing down to -60Ā°C and boil-in-the-bag heating up to 100Ā°C for up to 30 minutes.

  • Easy Heat Sealing & Opening

    Seals quickly using a household flat iron or hair straightener. Includes a pre-cut side tear notch above the opening for convenient hand-opening once sealed.
